1 Introduction
1.1 Scope of the document
This document presents the AT Command Set for SIMCom SIM7020 Series, including
SIM7020C, SIM7020E, SIM7020G, SIM7030 and SIM7060.
1.1 Related documents
You can visit the SIMCom Website using the following link:
http://www.simcom.com
1.2 Conventions and abbreviations
In this document, the GSM engines are referred to as following term:
ME (Mobile Equipment);
MS (Mobile Station);
TA (Terminal Adapter);
DCE (Data Communication Equipment) or facsimile DCE (FAX modem, FAX board);
In application, controlling device controls the GSM engine by sending AT Command via its
serial interface. The controlling device at the other end of the serial line is referred to as
following term:
TE (Terminal Equipment);
DTE (Data Terminal Equipment) or plainly "the application" which is running on an embedded
system.
1.3 AT Command syntax
The "AT" or "at" or "aT" or "At" prefix must be set at the beginning of each Command line. To
terminate a Command line enter <CR>.
Commands are usually followed by a response that includes.
"<CR><LF><response><CR><LF>"
Throughout this document, only the responses are presented,<CR><LF> are omitted
intentionally.
Th e AT Command set implemented by SIM7020 Series is a combination of 3GPP TS 27.005,
3GPP TS 27.007 and ITU-T recommendation V.25ter and the AT commands developed by
SIMCom.
Note: Only enter AT Command through serial port after SIM7020 Series is powered on and Unsolicited Result
SIMCOM CONFIDENITAL FILE
Smart Machine Smart Decision
SIM7020 Series_AT Command Manual_V1.02 16 2018-12-13
Code "RDY" is received from serial port. If auto-bauding is enabled, the Unsolicited Result Codes "RDY"
and so on are not indicated when you start up the ME, and the "AT" prefix, or "at" prefix must be set at the
beginning of each command line.
All these AT commands can be split into three categories syntactically: "basic", "S parameter",
and "extended". These are as follows:
1.3.1 Basic syntax
These AT commands have the format of "AT<x><n>", or "AT&<x><n>", where "<x>"is the
Command, and "<n>"is/are the argument(s) for that Command. An example of this is "ATE<n>",
which tells the DCE whether received characters should be echoed back to the DTE according to
the value of "<n>". "<n>" is optional and a default will be used if missing.
1.3.2 S Parameter syntax
These AT commands have the format of "ATS<n>=<m>", where "<n>" is the index of the S
register to set, and "<m>"is the value to assign to it. "<m>" is optional; if it is missing, then a
default value is assigned.
1.3.3 Extended Syntax
These commands can operate in several modes, as in the following table:
Table 1: Types of AT commands and responses
Test Command AT + <x>=? The mobile equipment returns the list of parameters
and value ranges set with the corresponding Write
Command or by internal processes.
Read Command AT + <x>? This command
returns the currently set value of the
parameter or parameters.
Write Command AT+<x>=<…> This command sets the user-definable parameter
values.
Execution
Command
AT+<x> The execution command reads non-variable
parameters affected by internal processes in the GSM
engine.
1.3.4 Combining AT commands on the same Command line
You can enter several AT commands on the same line. In this case, you do not need to type the
"AT" or "at" prefix before every command. Instead, you only need type "AT" or "at" the
beginning of the command line. Please note to use a semicolon as the command delimiter after
an extended command; in basic syntax or S parameter syntax, the semicolon need not enter, for
example: ATE1Q0S0=1S3=13V1X4;+IFC=0,0;+IPR=115200.
The Command line buffer can accept a maximum of 2048 characters (counted from the first
SIMCOM CONFIDENITAL FILE
Smart Machine Smart Decision
SIM7020 Series_AT Command Manual_V1.02 17 2018-12-13
command without "AT" or "at" prefix). If the characters entered exceeded this number then none
of the Command will executed and TA will return "ERROR".
1.3.5 Entering successive AT commands on separate lines
When you need to enter a series of AT commands on separate lines, please Note that you need to
wait the final response (for example OK, CME error, CMS error) of last AT Command you
entered before you enter the next AT Command.
1.4 Supported character sets
The SIM7020 Series AT Command interface defaults to the IRA character set. The SIM7020
Series supports the following character sets:
GSM format
UCS2
IRA
The character set can be set and interrogated using the "AT+CSCS" Command (3GPP TS
27.007). The character set is defined in GSM specification 3GPP TS 27.005.
The character set affects transmission and reception of SMS and SMS Cell Broadcast messages,
the entry and display of phone book entries text field and SIM Application Toolkit alpha strings.
1.5 Flow control
Flow control is very important for correct communication between the GSM engine and DTE.
For in the case such as a data or fax call, the sending device is transferring data faster than the
receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving
device should be capable to cause the sending device to pause until it catches up.
There are basically two approaches to achieve data flow control: software flow control and
hardware flow control. SIM7020 Series support both two kinds of flow control.
In Multiplex mode, it is recommended to use the hardware flow control.
1.5.1 Software flow control (XON/XOFF flow control)
Software flow control sends different characters to stop (XOFF, decimal 19) and resume (XON,
decimal 17) data flow. It is quite useful in some applications that only use three wires on the
serial interface.
The default flow control approach of SIM7020 Series is hardware flow control (RTS/CTS flow
control), to enable software flow control in the DTE interface and within GSM engine, type the
following AT Command:
AT+IFC=1, 1
SIMCOM CONFIDENITAL FILE
Smart Machine Smart Decision
SIM7020 Series_AT Command Manual_V1.02 18 2018-12-13
Ensure that any communications software package (e.g. Hyper terminal) uses software flow
control.
NOTE:
Software Flow control should not be used for data calls where binary data will be transmitted or
received (e.g. TCP/IP) as the DTE interface may interpret binary data as flow control characters.
1.5.2 Hardware flow control (RTS/CTS flow control)
Hardware flow control achieves the data flow control by controlling the RTS/CTS line. When the
data transfer should be suspended, the CTS line is set inactive until the transfer from the
receiving buffer has completed. When the receiving buffer is ok to receive more data, CTS goes
active once again.
To achieve hardware flow control, ensure that the RTS/CTS lines are present on your application
platform.
1.6 Definitions
1.6.1 Parameter Saving Mode
For the purposes of the present document, the following syntactical definitions apply:
- NO_SAVE: The parameter of the current AT command will be lost if module is rebooted or
current AT command doesn't have parameter.
- AUTO_SAVE: The parameter of the current AT command will be kept in NVRAM
automatically and take in effect immediately, and it won't be lost if module is rebooted.
- AUTO_SAVE_REBOOT: The parameter of the current AT command will be kept in
NVRAM automatically and take in effect after reboot, and it won't be lost if module is
rebooted.
- AT & W _ S AV E : The parameter of the current AT command will be kept in NVRAM by
sending the command of "AT&W".
- -: "-" means this AT command doesn't care the parameter saving mode.
1.6.2 Max Response Time
Max response time is estimated maximum time to get response, the unit is seconds.
"-" means this AT command doesn't care the response time.

2.1.19 ATS12 Set Escape Code Guard Time
This command sets the escape code guard time in fiftieths of a second. The escape guard time is
used to measure when to detect the +++ escape sequence has been entered by the PC in order to
drop out of data mode back to AT command mode.
The guard time determines the time that forms a guard period before and after three escape
sequence characters. In order to distinguish an escape sequence from just three escape sequence
characters in the data stream there is timing associated to the three escape sequence characters of
an escape sequence.
The time between the last byte of the data stream and the first escape sequence character must be
at least the guard time and the time between each escape sequence character of the escape

SIM7020 Series_AT Command Manual_V1.02 30 2018-12-13
sequence must be less than the guard time and no other byte is received after the third escape
sequence character for the time of the guard time. If an escape sequence is detected, the OK
result code will be sent to the DTE. Otherwise, the DCE will stay in data mode.

Parameters
<cid> (PDP Context Identifier) a numeric parameter that specifies a
particular PDP context definition.
The parameter is local to the UE-TE interface and is used in other PDP
context-related commands.
The range of permitted values (minimum value=1 or if the initial PDP
context is supported minimum value=0) is returned by the test form of the
command.
<PDP_type> (Packet Data Protocol type) a string parameter which
specifies the type of packet data protocol :
IP Internet Protocol (IETF STD 5)
IPV6 Internet Protocol, version 6 (IETF RFC 2460)
IPV4V6 Virtual <PDP_type>) introduced to handle dual IP stack
UE capability (see 3GPP Technical Specifications 24.301).
Non-IP Transfer of Non-IP data to external packet data Network
(see 3GPP Technical Specifications 24.301).
<APN> (Access Point Name) a string parameter, a logical name to
select the GGSN or the external packet data network. If the value is null or
omitted, then the subscription value will be requested.
<PDP_addr> A string parameter that identifies the UE in the address
space applicable to the PDP. If the value is null or omitted, then a value may
be provided by the TE during the PDP startup procedure or, failing that, a
dynamic address will be requested. The read form of the command will
continue to return the null string even if an address has been allocated
during the PDP startup procedure. The allocated address may be read using
the +CGPADDR command.
NOTE: For EPS, this field is omitted.
<d_comp> A numeric parameter that controls PDP data compression
(applicable for SNDCP only) (refer 3GPP TS 04.65)
0 off (default if value is omitted)
1 on (manufacturer preferred compression)
2 V.42bis
Other values are reserved.
<h_comp> A numeric parameter that controls PDP header compression
(refer 3GPP TS 04.65)
0 off (default if value is omitted)

Reference Note
- Only UART1 can enable csclk as 1 or 2.
- There are two caveats when you want to quit sleep mode in mode 2:
1, You should input some characters (at least one) to awake module
2, An interval time of 100ms more is necessary between waking characters
and following AT commands,otherwise the waking characters will not be
discarded completely,and messy codes will be produced which may leads
to UART baudrate re-adaptation.
- Scope of parameter <n> is different among SIM7020 series project,
please refer to chapter 21 for details.

Time
When mode is multi-IP state, the max response time75 seconds.
When mode is single state, and the state is IP INITIAL, the max response
time is 160 seconds.
Reference
Note
- This command allows establishment of
a TCP/UDP connection only
when the state is IP_INITIAL or IP_STATUS or IP_
CLOSED when it
is in single state.In multi-IP state, the state is in IP_STATUS
only,or,if
the module is deactivating.
So it is necessary to process
"AT+CIPSHUT" before user establishes
a TCP/UDP connection with
this command when the state is not IP INITIAL or IP STATUS.
- When module is in multi-IP state, before this command is executed, it
is necessary to process "AT+CSTT, AT+CIICR, AT+CIFSR".
