1.4 Definitions
In the GSM vocabulary, a call from GSM mobile to the PSTN is named “mobile
originated call” (MOC) or “outgoing call”, and a call from fixed network to a GSM mobile is
called “mobile terminated call” (MTC) or “incoming call”.

2 AT commands features
2.1 Wavecom line settings
A serial link handler is set with these default values (factory settings) :
- autobaud, 8 bits data, 1 bit stop, no parity, RTS/CTS flow control.
Please use the commands +IPR, +IFC, +ICF to change these settings.
2.2 Command line
The commands always start with AT (means Attention !) and finish with a <CR>
character.
2.3 Information responses and result codes
Responses start and end with <CR><LF>, except with the ATV0 (DCE response

3 General behaviors
3.1 SIM Insertion, SIM Removal
The SIM card Insertion and Removal procedures are supported. There are software
functions based on the reading of the hardware SIM presence pin. This pin state (open /
closed) is continuously watched.
When the SIM presence pin indicates a presence of a card in the SIM connector, the
module tries to set a logical SIM session. Depending on the fact that the detected card is a
SIM Card or not, the logical SIM session will be set or not. The AT+CPIN? Delivers the
following answers :
- If SIM presence pin indicates “nothing”, the answer to AT+CPIN? Is
“+CME ERROR 10” (SIM not inserted)
- If SIM presence pin indicates “something”, and the inserted Card is a
SIM Card, the answer to AT+CPIN? Is “+CPIN: xxx” depending on the
SIM PIN state.
- If SIM presence pin indicates “something”, and the inserted Card is
not a SIM Card, the answer to AT+CPIN? Is CME ERROR 10
- These last two status are not immediately available due to the
background initialisation. Between the hardware SIM presence pin
indication of “something” and the previous results the AT+CPIN?
Sends “+CME ERROR: 515” (Please wait, init in progress)
When the SIM presence pin indicates an absence, and if a SIM Card was previously
inserted, an IMSI detach procedure is done, and all the user data are removed from the
module (Phonebooks, SMS etc.). The module is then in emergency mode.

16
3.2 Backgroung initialisation
After the PIN entry, some SIM user data files are loaded in the module (Phonebooks,
SMS status …), but it can take a long time for huge phonebooks reading. The AT+CPIN?
Command answers just after verification of the PIN. User Datas are loaded after the answer
in background.
This means, that some datas may not be available just after the OK from the PIN
Entry. The reading of phonebooks will then be refused by the following “+CME ERROR: 515”
or “+CMS ERROR: 515” meaning “please wait, service is not available, init in progress”.
That kind of answer may be sent by the module at several steps :
- When trying to execute another AT command before the end
(response) of the previous one.
- when swapping from (or to) ADN to (or from) FDN and trying to read
immediately the concerned phonebook ;
- when asking for +CPIN? Status just after a SIM insertion when the
module has not determined if the inserted card is a valid SIM Card.

4.11 Set phone functionality +CFUN
4.11.1 Description :
This command selects the level of functionality in the mobile station.
• When the application wants to stop the module to power off, or if the
application wants to force the module to execute a IMSI DETACH
procedure, then it has to send :
AT+CFUN=0 (same as AT+CPOF)
This command executes a IMSI DETACH and makes a backup of some internal
parameters in the SIM and the EEPROM. Then no access to the SIM card is possible.
If the mobile is not powered off after this command, it shall receive another command
to re-start the whole GSM process.
If the mobile is turned off after this command, then the power on will automatically
execute the start of the whole GSM process.
When the application wants to re-start the module (after having done a AT+CFUN=0
command, and without having cut the power supply), it has to send :
AT+CFUN=1
AT commands interface

24
This command starts again all the GSM stack and GSM functionality, a complete
software reset is done. All parameters are reset to their previous E2P value if AT&W was not
used.
If you write entries in phonebook (+CPBW) and then reset the module directly
(AT+CFUN=1, without any AT+CFUN=0 before), some entries may not be written (SIM task
does not have the time to write entries in SIM card)
Also, the OK response will be sent at the last defined baud rate defined by +IPR
command. With autobauding the response can be at a different baud rate, so it is better to
save the defined baud rate with AT&W before directly send the AT+CFUN=1 command.

5 Call Control commands
5.1 Dial command D
5.1.1 Description :
The ATD command is used to set a speech, data or fax call. According to GSM
02.30, dial command also controls supplementary services.
For a data or fax call, the application sends to the GSM module the following ASCII
string : (the bearer has to be previously selected with the +CBST command)
ATD<nb> where <nb> is the called phone number.
For a voice call, the application sends to the GSM module the following ASCII
string : (the bearer may be previously selected, if not a default bearer is used)
ATD<nb>; where <nb> is the called phone number.
Please, notice that in case of international number, the local international
prefix has not to be set (usually 00) but need to be replaced by the ‘+’
character.
Example : to establish a voice call to Wavecom from another country, the AT
command shall be : ATD+33146290800;

To select the operator, three possibilities exist :
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
53
1- The mobile enters the manual mode, and then tries to find an operator which is
indicated by the application. If it finds and registers correctly, then the mobile stays in idle
mode.
2- The mobile enters the automatic mode, and then tries to find the home operator. If
it finds and registers correctly, then the mobile stays in idle mode ; if not, the mobile searches
automatically another network.
3- The mobile enters the manual/automatic mode, and then tries to find an operator
which is indicated by the application (like in manual mode) . If this attempt fails the
automatic mode is entered. If this attempt is successful, the operator indicated by the
application is selected and registered, then the mobile enters the automatic mode.
Read command returns the current mode and the currently selected operator. Just
notice that in manual mode, this PLMN could not be the one the mobile has to register
(searching phase).
6.2.2 Syntax :
To force an attempt to select and register a network operator, the application must
send the following command :
Command syntax: AT+COPS=<mode>, [<format> [ , <oper> ] ]
Possible responses for AT+COPS=<mode>:
OK (Network is selected in full service)
+CME ERROR: 30 (No network service),

7 Security commands
7.1 Enter PIN +CPIN
7.1.1 Description :
This command is used to enter ME passwords (CHV1 / CHV2 / PUK1 / PUK2…)
which are needed before the use of any other ME functionality. The CHV1/CHV2 length is
between 4 and 8 digits, the PUK1/PUK2 length is 8 digits only.
If the user application tries to set an outgoing call before having validated the SIM PIN
code (CHV1), then the GSM module will refuse the “ATD” command with a
“+CME ERROR: 11” (SIM PIN required).
It’s up to the application to validate the PIN after each reset or power on if the PIN
was enabled
7.1.2 Syntax :
Command syntax : AT+CPIN=<pin>
Command Possible responses
AT+CPIN=1234
Note : Enter PIN
OK
Note : PIN code is correct
AT+CPIN=5678
Note : Enter PIN
+CME ERROR : 3
Note : Operation not allowed, PIN previously
entered
After 3 unsuccessful codes, the PUK will then be required. The PUK validation forces
the user to enter as a second parameter a new PIN code which will be the new PIN code if
the PUK validation succeeds. The CHV1 is then enabled if the PUK1 is correct. The
application shall therefore use the command :
AT+CPIN=<Puk>,<NewPin>
Command Possible responses

Note : Incorrect PUK
AT+CPIN=12345678,1234
Note : Enter PUK and new PIN, 2nd attempt
OK
Note : PUK correct, new PIN stored
To know which code has to be entered (or not), the following interrogation command
can be used :
AT+CPIN?
The possible responses are :
+CPIN: READY ME is not pending for any password
+CPIN: SIM PIN CHV1 is required
+CPIN: SIM PUK PUK1 is required
+CPIN: SIM PIN2 CHV2 is required
+CPIN: SIM PUK2 PUK2 is required
+CPIN: PH-SIM PIN SIM lock (phone-to-SIM) is required
+CPIN: PH-NET PIN Network personnalisation is required
+CME ERROR: <err> SIM failure (13) absent (10) etc…
Please note that in this case the mobile does not finish its response with the OK string.
The response +CME ERROR : 13 (SIM failure) is returned after 10 unsuccessful PUK
presentations. The SIM card is then out of order and shall be replaced by a new one.
Example : 3 failed PIN validations + 1 successful PUK validation

If the user tries to do something which requires PIN2 (CHV2) the GSM module will
refuse his action with a “+CME ERROR: 17” (SIM PIN2 required). Then the GSM module is
waiting SIM PIN2 to be given.
Of course if SIM PIN2 is blocked , SIM PUK2 is required instead of SIM PIN2.
For instance, the GSM module needs PIN2 to write in the fixed dialling phonebook
(FDN) , so if SIM PIN2 authentification has not been done during the current cession the SIM
PIN2 is required:
Command Possible responses
AT+CPBS=”FD”

Note : Now writing in FDN is allowed
Please note that the GSM module only ask once PIN2 or PUK2, so if they aren’t
entered correctly, the next +CPIN? Command will return “+CPIN: READY”.
Remark
In the way Application to GSM, an “h” character shall be added before the PIN value if
cyphering mode (with D.E.S algorithm ) is on. See +EXPKEY command.

7.2.1 Description :
This specific command is used to validate the PIN2 code (CHV2), or to validate the
PUK2 code (UNBLOCK CHV2) and to define a new PIN2 code.
Of course +CPIN command allows to validate PIN2 or PUK2 codes but only when the
last executed command resulted in PIN2 authentification failure.
The PIN2 length is between 4 and 8 digits, the PUK2 length is 8 digits only.
7.2.2 Syntax :
Command syntax : AT+CPIN2=<pin2>
Command Possible responses
AT+CPIN2=1234
Note : Enter PIN2
OK
Note : PIN2 code is correct
AT+CPIN2=5678
Note : Enter PIN2
+CME ERROR: 3
Note : Operation not allowed, PIN2 previously
entered
After 3 unsuccessful codes, the PUK2 will then be required. The PUK2 validation
forces the user to enter as a second parameter a new PIN2 code which will be the new PIN2
code if the PUK1 validation succeeds. The application shall therefore use the command :

In TEXT mode, only positive acknowledgement to the network (RP-ACK) is possible.
In PDU mode, either positive (RP-ACK) or negative (RP-ERROR) acknowledgement
to the network is possible.
Acknowledge with +CNMA is possible only if +CSMS parameter is set to 1
(+CSMS=1) when a +CMT or +CDS indication is shown (see +CNMI command).
If no acknowledgement is given within the network-timeout, RP-ERROR is send to the
network, then <mt> and <ds> parameters of +CNMI command are reset to zero (don’t show
new message indication).

9.5 Preferred Message Format +CMGF
9.5.1 Description :
The formats implemented are the text mode and the PDU mode.
In PDU mode, a complete SMS Message including all header information is passed
as a binary string (in hexadecimal format, so only this set of characters is allowed :
{‘0’,’1’,’2’,’3’,’4’,’5’,’6’,’7’,’8’,’9’, ‘A’, ‘B’,’C’,’D’,’E’,’F’} ). Each pair or characters is converted to
a byte (ex : ‘41’ is converted to the ASCII character ‘A’, whoes ASCII code is 0x41 or 65).
In Text mode, every commands and responses are in ASCII characters.
The chosen format is stored in EEPROM by the command +CSAS.

9.17 Service center address +CSCA
9.17.1 Description
This command shall be used to indicate to which service center the message has to
be sent.
The GSM module has no default value for this address. If the application tries to send
a message without having indicated the service center address, an error will be generated.
So, the application has to indicate this address when initializing. This address is then
valid all the time. The application may change it if needed.

9.20 Message status modification +WMSC
9.20.1 Syntax :
Command syntax : AT+WMSC= <loc>, <status>
<loc> location number of the stored message (integer)
<status> new status to be stored, as for +CMGL command
Possible responses:
OK if the location is valid
+CMS ERROR: 321 if <loc> is invalid or free
+CMS ERROR: 302 if the new <status> and the previous one are
incompatible (1)
Note 1 : The accepted status changes are from READ to NOT READ and vice versa, and
from SENT to NOT SENT and vice versa.
If all the parameters are correct, the module overwrites the whole SMS in the SIM. Only the
first byte (Status byte) is changed.
9.21 Message overwriting +WMGO
9.21.1 Description :
The +CMGW writes a SMS to the first free location. To write a SMS to a specified
location, the +WMGO specific command forces the module to write a SMS (with +CMGW
command) to the location specified with +WMGO, but just for one +CMGW command.
9.21.2 Syntax :
Command syntax : AT+WMGO= <loc>
<loc> location number of the SIM record to write or overwrite
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
111
Possible responses:
OK if <loc> is a valid SMS location, for AT+WMGO=? And
for AT+WMGO?
+CMS ERROR: 321 if <loc> is out of the SIM capacity range.
+WMGO: <loc> for AT+WMGO?
Then on the next AT+CMGW command, the record number used will be the one
specifed by AT+WMGO command. The location is then forgotten, and in order to make a
second overwrting, the +WMGO has to be used again.
If the external application specifies a free location, and if an incoming message is
received before the AT+CMGW command, the module may store the incoming message in a
free location, which could be unfortunately the one specified by +WMGO (the module does
not prevent this case). Then if the user issues a AT+CMGW command, without changing the
AT+WMGO location, the new message will be overwritten !
Be aware that this location number is not kept over a software reset.

options should be selected.
+CCUG command is used to :
- activate/deactivate the control of the CUG information for all following
outgoing calls.
- select a CUG index,
- suppress the outgoing access (OA). The OA allows a member of a
CUG to place calls outside the CUG.
- Suppress the preferential CUG. The preferential is the default CUG
used by the network when it does not receive explicit CUG index.

the possible speeds which can be used by DCE.
An autobauding is provided which operates from 2400 to 19200 baud. However some
constraints have to be dealt with :
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
164
• any AT command issued by DTE must start with a capital ‘A’ and ‘T’
(or ‘\’). If not, DCE may send back some garbage characters and get
de-synchronized. Shoud it happen, DTE shall just issue once or twice
‘AT\r’ (at 2400 or 4800 baud) or just ‘AT’ (at 9600 baud) to get the
modem re-synchronized.
• the DTE shall wait for 1ms after receiving the last character of the AT
response (which is always ‘\n’ or 0x0A) to send a new AT command at
either the same rate or a new rate. Shoud this delay ignored, DCE can
get de-synchronised. Once again, sending once or twice ‘AT\r’ or just
‘AT’ causes the DCE to recover.
Be careful : when starting up if autobauding is enabled and no AT command has been
received yet, the module sends all unsolicited responses (like RING) at 9600 baud.
14.2 DTE-DCE character framing +ICF
14.2.1 Description :
This command is used to determine the local serial port start-stop (asynchronous)
character framing that the DCE shall use.

Note 1) setting a character framing different from 8N1 will disable autobauding (in the case it
was activated). However setting it back to 8N1 will not re-enable autobaud.
Note 2) setting the framing to 8N1 will let the autobauding enabled, if it was already enabled
(implying framing was already 8N1).
14.3 DTE-DCE local flow control +IFC

1 : Xon/Xoff local circuit 103 (not supported)
2 : RTS (Supported)
3 : Xon/Xoff global on circuit 103 (not supported)
Important note : when this parameter is set to 2 (DTE invokes flow control through
RTS) the behavior of the DCE is the following :
If the DCE has never detected RTS in high (or ON) condition since startup then it
ignores RTS, assuming this signal is not connected.
As soon as DCE detects RTS high, then this signal acts upon it. Therefore
subsequent RTS transition to OFF will prevent DCE from sending any further data in online
and in offline as well.
This behavior allows the user to use the default settings (hardware flow control) and
let RTS disconnected. In the case RTS is connected and is high at least once then it acts
upon DCE.
< DTE_by_DCE > 0 : none (Supported)
1 : Xon/Xoff circuit 104 (not supported)
2 : CTS (Supported)
When this parameter is set to 0 (none) then CTS is kept high all the time.

15 Specific AT commands
15.1 Cell environment description +CCED
15.1.1 Description :
This command can be used by the application to retrieve the cell parameters of the
main cell and of up to six neighbour cells.
Two ways may exist for the external application to know these cell parameters : on
request of the application, or automatically by the module every 5 seconds.
The automatic mode is not supported during communication or registration.
15.1.2 Syntax :
Command syntax: AT+CCED=<mode>[, <requested dump>]
15.1.3 Defined values :
<mode> 0 : One shot requested
1 : Automatic shots requested
2 : Stop automatic shots
<requested dump> 1 : Main Cell :
if the Cell Identity is available
MCC, MNC, LAC, CI, BSIC, BCCH Freq
(absolute), RxLev, RxLev Full, RxLev Sub,
RxQual, RxQual Full, RxQual Sub,Idle TS
if the Cell Identity is not available
MCC, MNC, LAC,, BSIC, BCCH Freq
(absolute), RxLev, RxLev Full, RxLev Sub,
RxQual, RxQual Full, RxQual Sub,Idle TS
2 : Neighbour1 to Neighbour6 :
if the Cell Identity is available
MCC, MNC, LAC, CI, BSIC, BCCH Freq
(absolute), RxLev
if the Cell Identity is not available
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
177
MCC, MNC, LAC,, BSIC, BCCH Freq
(absolute), RxLev
4 : Timing Advance
Combination (addition of the values) of the requested dumped are supported.
Notice that in idle mode, only RxLev measures (on the main cell and on the neighbour
cells) are done. The value of these RxLev is set in the RxLev Full field for the main cell.
The response will be :
+CCED :<value>, … , <value>
OK
Where <value> is the ASCII string of the values (in decimal except LAC and CI values
are in hexadecimal) of the parameters. If a field can not be measured – or has no sense –
the parameter is not filled (two consecutive commas are then found).
If the <requested dump> parameter is absent, this of the last +CCED command (or 15
by default) will be taken.
Values of MCC/MNC are set to 0 in case of “No service”
15.2 Automatic RxLev indication +CCED
15.2.1 Description :
The CCED command has been extended to indicate the received signal strength
indication (rssi) of the main cell. The principle of the command does not change :
15.2.2 Syntax :
Command Syntax: AT+CCED=<mode>[, <requested dump>]
15.2.3 Defined values :
<mode> 0 : One shot requested
1 : Automatic shots requested
2 : Stop automatic shots
<requested dump> 8 : Main cell RSSI indications (RxLev) from 0 to 31
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
178
The response will be a +CSQ answer and not a +CCED answer. The 07.07 format for
the +CSQ is respected. The <ber> is not evaluated by this command, so the <ber> value will
always be 99.
+CSQ :<rssi>, 99
OK
This +CSQ answer, when automatic shots are selected, is sent every time the <rssi>
measured by the module changes. This automatic shots are supported in idle mode and
during communication.
Combination (addition of the values) of the requested dumped (1,2,4,8) are supported
but the activation or deactivation of this flow (8) does not affect the other flows. Both answer
+CCED and +CSQ may be then generated.
If the <requested dump> parameter is absent, the last +CCED command parameter (or
15 by default) will be taken.
15.3 General Indications +WIND
15.3.1 Description :
Wavecom introduced a general mechanism to send unsollicited non standardized
indication to the customer application. The yet identified unsollicited non standardized
indications are :
- indication of a physical change on the SIM presence pin from
connector (meaning SIM inserted, SIM removed)
- indication during a mobile originated call establishement, that the
calling party is ringing.
- Indication of the availability of the module, after boot, to receive AT
commands
For each of these indications, a “bit flow” has to be indicated.
15.3.2 Syntax :
Command syntax: AT+WIND= <IndLevel >
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
179
15.3.3 Defined values :
<IndLevel> 1 (bit-0) : Hardware SIM Insert / Remove indications
(Rack open/close) or SIM presence after software reset
2 (bit-1) : Calling party alert indication
4 (bit-2) : Module is ready to treat AT commands (except
phonebooks, AOC, SMS), but still in emergency mode.
8 (bit-3) : Indication that the module is ready to treat all
AT commands, at the end of init or after swapping to
ADN in case of FDN configuration
16 (bit-4) : Indication that a new call identifier has been created
( after an ATD command, +CCWA indication)
32 (bit-5) : Indication that an active, held or waiting call has been
released by network or other party
64 (bit-6) : Network service available indication
128 (bit-7) : Network lost indication
If <IndLevel> is equal to 0 (default value), no unsolicited
“+WIND: <IndNb>” will occur.
Combination (addition of the values) shall be used to allow more than one indication
flow.
0 Ω
ΩΩ
Ω IndLevel Ω
ΩΩ
Ω 255
The answer is OK if the value are in the previous range.
The unsolicited answer will then be :
+WIND : <event> [ ,<idx> ]
<idx>: Call identifier, defined in +CLCC command.
The supported events are:
<event> 0 : The SIM presence pin has been detected as “SIM removed”
(depending from the 0 bit flow)
1 : The SIM presence pin has been detected as “SIM inserted”

16 SIM TOOLKIT
16.1 Overview of SIM Application ToolKit
16.1.1 Summary
The SIM ToolKit, also known as ‘SIM Application ToolKit’ introduces new
functionalities, which open the way to a broad range of value added services.
The principle is to allow service providers to develop new applications (i.e. for
banking, travel, ticket booking …) for subscriber’s and to download them into the SIM.
This solution allows future services to be accessible to the user by adding new SIM-
based applications without modifying the handset.
16.1.2 Functionality
SIM Toolkit refers to the functionalities described in the GSM Technical specification
11.14.
It introduces about twenty five new commands for the SIM. Three classes of ToolKit
functionalities have been defined, with class 1 offering a subset of commands and class 3
offering the full range of commands (See the table in APPENDIX B).
The SIM Application Toolkit supports:
☞ profile download,
☞ proactive SIM,
☞ data download into the SIM.
☞ menu selection,
☞ call control by SIM.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
201
16.1.3 Profile download
The Profile Download instruction is sent by the customer application to the SIM as
part of the initialization. It is used to indicate which SIM Application Toolkit features the
customer application supports.
The AT command used for this feature is +STSF (SIM ToolKit Set Facilities).
16.1.4 Proactive SIM
A proactive SIM provides a mechanism whereby the SIM can ask the customer
application to perform certain actions.
These actions include:
• display menu,
• display given text,
• get user input,
• send a short message,
• play the requested tone,
• set up a call,
• provide location information.
This mechanism allows SIM applications to generate powerful menu-driven
sequences on the customer application and to use services available on the network.
The commands used for this feature are:
+STIN (SIM Toolkit Indication),
+STGI (SIM Toolkit Get Information),
+STGR (SIM Toolkit Give Response).
16.1.5 Data Download to SIM
Data downloading to the SIM allows data (SMS, phonebook…) or programs (Java
applets) received by SMS or by Cell Broadcast to be transferred directly to the SIM
Application.
This feature does not need any AT command. It is transparent to the customer application.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
202
16.1.6 Menu Selection
A set of menu items is supplied by the SIM Application ToolKit. The menu selection
command can then be used to inform the SIM Application on which menu item is selected.
The commands used for this feature are +STIN, +STGI and +STGR.
16.1.7 Call control by SIM
The call control mechanism allows the SIM to check all dialed numbers,
supplementary service control strings and USSD strings before connecting to the network.
This gives the SIM the ability to allow, bar or modify the string before the operation starts.
The commands used for this feature are :
+STCR (SIM Toolkit Control Response),
+STGR (SIM Toolkit Give Response).

203
16.2 Exchanged messages during a SIM ToolKit operation.
The following scheme shows the SIM Toolkit functionnalities commands and
unsolicited results that will be implemented.
On the first step the customer application informs the WAVECOM module which
facilities are supported. This operation is performed with the +STSF (SIM ToolKit Set
Facilities) command, which also allows to activate or deactivate the SIM Toolkit functionality.
On the second step an unsolicited result +STIN (SIM ToolKit indication) is sent by the
module, in order to indicate the customer application which command type the SIM
Application Toolkit is running on the SIM card.
On the third step the customer application uses the +STGI (SIM ToolKit Get
Information) command to get all the information about the SIM ToolKit command, given by
+STIN.
On the fourth step the customer application uses the +STGR (SIM Toolkit Give
Response) to send its response (if any) to the SIM ToolKit Application.
WAVECOM
Module
Customer
Application
+STSF=X,XXXXXXXX
+STIN=X
+STGI=X
+STGI response
+STGR=X,XXXXXX
STEP 1: Configuration and Activation
STEP 2: SIM sends pro-active command
STEP 3: Customer application gets all the information.
Step 4: User response is sent to the SIM.
+STCR:X
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
204
The +STCR (SIM Toolkit Control response) indication is an unsolicited result sent by
the SIM when Call control functionality is activated and before the customer application has
performed any outgoing call,SMS, SS, or USSD.

2 Configure the SIM Toolkit functionalities.
<Config> (160060C0 – 5F9FFFF7) (hex format)
<Timeout> 1-255 Timeout for user reponses (muiltiple of 10 secondes).
The activation or deactivation of the SIM Toolkit functionalities requires the use of +CFUN
(Set phone functionality) command to reboot the module.
The <Config> parameter contains the coding of TERMINAL PROFILE, precisely the list of
SIM Application Toolkit facilities that are supported by customer application.
The <Timeout> parameter contains the time (multiple of 10 secondes) dispose the user to
anwer (for select an item, input a text …).
Note: Some bits concerns the WAVECOM module and not the customer application. The
WAVECOM module sets automatically these bits to either 0 or 1 whatever the user
enters with +STSF command. Those values are given in Appendix B.
Each facility is coded on 1 bit:
• bit = 1: facility supported by the customer application.
• bit = 0: facility not supported by the customer application.
Only the first four byte of TERMINAL PROFILE (Class 2) can be configured, the other
are set to 0. (See structure of TERMINAL PROFILE in APPENDIX C)

18.6 GSM 04.11 Annex E-2: Mobile originating SM-transfer
These error causes could appear for SMS commands (+CMGS, +CMSS, +CMGD…)
Cause no 1: "Unassigned (unallocated) number"
This cause indicates that the destination requested by the Mobile Station cannot be
reached because, although the number is in a valid format, it is not currently assigned
(allocated).
Cause no 8: "Operator determined barring"
This cause indicates that the MS has tried to send a mobile originating short message
when the MS's network operator or service provider has forbidden such transactions.
Cause no 10: "Call barred"
This cause indicates that the outgoing call barred service applies to the short
message service for the called destination.
Cause no 21: "Short message transfer rejected"
This cause indicates that the equipment sending this cause does not wish to accept
this short message, although it could have accepted the short message since the equipment
sending this cause is neither busy nor incompatible.
Cause no 27: "Destination out of service"
This cause indicates that the destination indicated by the Mobile Station cannot be
reached because the interface to the destination is not functioning correctly. The term "not
functioning correctly" indicates that a signalling message was unable to be delivered to the
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
229
remote user; e.g., a physical layer or data link layer failure at the remote user, user
equipment off-line, etc.
Cause no 28: "Unidentified subscriber"
This cause indicates that the subscriber is not registered in the PLMN (i.e. IMSI not
known)
Cause no 29: "Facility rejected"
This cause indicates that the facility requested by the Mobile Station is not supported
by the PLMN.
Cause no 30: "Unknown subscriber"
This cause indicates that the subscriber is not registered in the HLR (i.e. IMSI or
directory number is not allocated to a subscriber).
Cause no 38: "Network out of order"
This cause indicates that the network is not functioning correctly and that the
condition is likely to last a relatively long period of time; e.g., immediately reattempting the
short message transfer is not likely to be successful.
Cause no 41: "Temporary failure"
This cause indicates that the network is not functioning correctly and that the
condition is not likely to last a long period of time; e.g., the Mobile Station may wish to try
another short message transfer attempt almost immediately.
Cause no 42: "Congestion"
This cause indicates that the short message service cannot be serviced because of
high traffic.
Cause no 47: "Resources unavailable, unspecified"
This cause is used to report a resource unavailable event only when no other cause
applies.
Cause no 69: "Requested facility not implemented"
This cause indicates that the network is unable to provide the requested short
message service.
Cause no 81: "Invalid short message transfer reference value"
This cause indicates that the equipment sending this cause has received a message
with a short message reference which is not currently in use on the MS-network interface.
AT commands interface
This confidential document is the property of WAVECOM and may not be copied or circulated without permission
230
Cause no 95: "Invalid message, unspecified"
This cause is used to report an invalid message event only when no other cause in
the invalid message class applies.
Cause no 96: "Invalid mandatory information"
This cause indicates that the equipment sending this cause has received a message
where a mandatory information element is missing and/or has a content error (the two cases
are undistinguishable).
Cause no 97: "Message type non-existent or not implemented"
This cause indicates that the equipment sending this cause has received a message
with a message type it does not recognize either because this is a message not defined or

23 APPENDIX E: Coding of Alpha fields in the SIM
for UCS2
The coding can take one of three forms. If the ME supports UCS2 coding of alpha fields
in the SIM, the ME shall support all three coding schemes for character sets containing 128
characters or less; for character sets containing more than 128 characters, the ME shall at
least support the first coding scheme. If the alpha field record contains GSM default alphabet
characters only, then none of these schemes shall be used in that record. Within a record,
only one coding scheme, either GSM default alphabet, or one of the three described below,
shall be used.
1) If the first octet in the alpha string is '80', then the remaining octets are 16 bit UCS2
characters, with the more significant octet (MSO) of the UCS2 character coded in the
lower numbered octet of the alpha field, and the less significant octet (LSO) of the
UCS2 character is coded in the higher numbered alpha field octet, i.e. octet 2 of the
alpha field contains the more significant octet (MSO) of the first UCS2 character, and
octet 3 of the alpha field contains the less significant octet (LSO) of the first UCS2
character (as shown below). Unused octets shall be set to 'FF', and if the alpha field is
an even number of octets in length, then the last (unusable) octet shall be set to 'FF'.
Example 1
Octet 1 Octet 2 Octet 3 Octet 4 Octet 5 Octet 6 Octet 7 Octet 8 Octet 9
'80' Ch1MSO Ch1LSO Ch2MSO Ch2LSO Ch3MSO Ch3LSO 'FF' 'FF'
2) If the first octet of the alpha string is set to '81', then the second octet contains a
value indicating the number of characters in the string, and the third octet contains an 8
bit number which defines bits 15 to 8 of a 16 bit base pointer, where bit 16 is set to
zero, and bits 7 to 1 are also set to zero. These sixteen bits constitute a base pointer to
a "half-page" in the UCS2 code space, to be used with some or all of the remaining
octets in the string. The fourth and subsequent octets in the string contain codings as
follows; if bit 8 of the octet is set to zero, the remaining 7 bits of the octet contain a
GSM Default Alphabet character, whereas if bit 8 of the octet is set to one, then the
remaining seven bits are an offset value added to the 16 bit base pointer defined
earlier, and the resultant 16 bit value is a UCS2 code point, and completely defines a
UCS2 character.

Example 2
Octet 1 Octet 2 Octet 3 Octet 4 Octet 5 Octet 6 Octet 7 Octet 8 Octet 9
'81' '05' '13' '53' '95' 'A6' 'XX' 'FF' 'FF'
In the above example;
- Octet 2 indicates there 5 characters in the string
- Octet 3 indicates bits 15 to 8 of the base pointer, and indicates a bit pattern of 0hhh
hhhh h000 0000 as the 16 bit base pointer number. Bengali characters for example
start at code position 0980 (0000 1001 1000 0000), which is indicated by the coding
'13' in octet 3 (shown by the italicised digits).
- Octet 4 indicates GSM Default Alphabet character ‘53’, i.e. "S".
- Octet 5 indicates a UCS2 character offset to the base pointer of '15', expressed in
binary as follows 001 0101, which, when added to the base pointer value results in a
sixteen bit value of 0000 1001 1001 0101, i.e. '0995', which is the Bengali letter KA.
Octet 8 contains the value 'FF', but as the string length is 5, this a valid character in
the string, where the bit pattern 111 1111 is added to the base pointer, yielding a
sixteen bit value of 0000 1001 1111 1111 for the UCS2 character (i.e. '09FF').
3) If the first octet of the alpha string is set to '82', then the second octet contains a
value indicating the number of characters in the string, and the third and fourth octets
contain a 16 bit number which defines the complete 16 bit base pointer to a "half-
page" in the UCS2 code space, for use with some or all of the remaining octets in the
string. The fifth and subsequent octets in the string contain codings as follows; if bit 8
of the octet is set to zero, the remaining 7 bits of the octet contain a GSM Default
Alphabet character, whereas if bit 8 of the octet is set to one, the remaining seven bits
are an offset value added to the base pointer defined in octets three and four, and the
resultant 16 bit value is a UCS2 code point, and defines a UCS2 character.

Octet 1 Octet 2 Octet 3 Octet 4 Octet 5 Octet 6 Octet 7 Octet 8 Octet 9
'82' '05' '05' '30' '2D' '82' 'D3' '2D' '31'
In the above example
- Octet 2 indicates there are 5 characters in the string
- Octets 3 and 4 contain a sixteen bit base pointer number of '0530', pointing to the
first character of the Armenian character set.

- Octet 5 contains a GSM Default Alphabet character of '2D', which is a dash "-".
- Octet 6 contains a value '82', which indicates it is an offset of '02' added to the base
pointer, resulting in a UCS2 character code of '0532', which represents Armenian
character Capital BEN.
- Octet 7 contains a value 'D3', an offset of '53', which when added to the base pointer
results in a UCS2 code point of '0583', representing Armenian Character small
PIWR.

24 APPENDIX F: Specification of Power Down
Control via RS232
This appendix aims at describing how the power down mode of the Wismo can be activated
and disactivated via the RS232 serial link.
In this document, the term “DTE” refers to the customer device driving the Wismo, which is
referred to as the “DCE”.
The terms referring to the RS232 signals and levels are used according to recommendations
V.24 and V.28. However they are worth remembering:
DTR is the circuit 108/2, TX is the circuit 103, RX is the circuit 102 and CTS is the circuit 106.
The logical level “HIGH or ON” corresponds to the electrical level of 12 V, whereas the level
“LOW or OFF” corresponds to –12 V.
Basically the activation and disactivation is always initiated from the DTE and is carried out
through the handshaking of DTR and CTS.
The power down mode can be entered only when the DCE is idle, i.e. when no connection to
the network is in progress.
Into the details :
Whenever the DTE requests the DCE to enter the power down mode, the DTE drops (ON-to-
OFF transition) DTR. From this time on, the DTE must not send any more characters on the
TX line i.e. even the TX FIFO must be empty.
The DCE acknowledges entry in the power down mode by dropping CTS, which can occur at
maximum 5s after the DTR drop. However during that latency period the DTE is prohibited
from sending any more AT commands.
AT responses can be sent back to the DTE even if the DCE is in power down mode (actually
the DCE exits the power down mode, sends the AT response and enters back the power
down mode). Therefore the DTE can drop DTR just after having sent an AT command and
before receiving the AT response.
The DCE is made to exit the power down mode by raising the DTR. DCE is not ready to
receive further AT commands until it raises in turn CTS, which can take up to 2s from the
DTR raise.
Herebelow is a diagram depicting the handshaking:

Description of the stages:
1: the DTE sends an AT command
2: the DTE drops DTR to make the DCE enter the power down mode. Warning: this mode
will not really entered until CTS is dropped (stage 4). The DTE could also have dropped DTR
after receiving the AT response (stage 3).
3: the DCE sends back the AT response (if any)
4: the DCE drops CTS and does enter the power down mode.
5: the DCE sends back an unsolicited response (for instance a RING or +SMTI (incoming
SMS indication))
6: the DTE wants to reply to that unsolicited response so it causes the DCE to exit the power
down mode by raising its DTR.
7: in turn the DCE acknowledges the exit of the power donw mode by raising CTS.
8) & 9) exchange of AT commands/responses.
Note 1): The DTE must not send any AT commands from stage 2 on up to stage 7.
Note 2): During the latency period (between stages 2 and 4) should the DTE want to abort
the power down mode, it raises DTR and should wait for 150us before assessing CTS. If
CTS is still high than the DCE has aborted the power down mode and is ready to receive AT
commands.
The 150us wait should get around the race condition between DTR raise and CTS drop.
