Between Customer Application and the Module, standardized RS–232 interface is used for the
communication, and default values for the interface settings as following:
115200bps, 8 bit data, no parity, 1 bit stop, no data stream control.
2.2 AT command syntax
The prefix “AT ” or “at” (no case sensitive) must be included at the beginning of each command line
(except A/ and +++), and the character <CR> is used to finish a command line so as to issue the command
line to the Module. It is recommended that a command line only includes a command.
When Customer Application issues a series of AT commands on separate command lines, leave a pause
between the preceding and the following command until information responses or result codes are retrieved
by Customer Application, for example, “OK” is appeared. This advice avoids too many AT commands are
issued at a time without waiting for a response for each command.
In the present document, AT commands are divided into three categories: Basic Command, S Parameter
Command, and Extended Command.
1. Basic Command
The format of Basic Command is “AT<x><n>” or “AT&<x><n>”, “<x>” is the command name, and “<n>”
is/are the parameter(s) for the basic command, and optional. An example of Basic Command is “AT E <n>”,
which informs the TA/DCE whether received characters should be echoed back to the TE/DTE according to
the value of “<n>”; “<n>” is optional and a default value will be used if omitted.
2. S Parameter Command
The format of S Parameter Command is “ATS <n>=<m>”, “<n>” is the index of the S–register to set, and
“<m>” is the value to assign to it. “<m>” is optional; in this case, the format is “ATS<n>”, and then a
default value is assigned.
3. Extended Command
The Extended Command has several formats, as following table list:

Command Type Syntax Comments
Test Command
AT+<NAME>=?
Test the existence of the command; give some
information about the command subparameters.
Read Command AT+<NAME>? Check the current values of subparameters.
Write Command AT+<NAME>=<…> Set user-definable subparameter values.
Execution Command AT+<NAME> Read non-variable subparameters determined by
internal processes.
NOTE: The character “+” between the prefix “AT” and command name may be replaced by other
character. For example, using “#” or “$”instead of “+”.
2.3 Information responses
If the commands included in the command line are supported by the Module and the subparameters are
correct if presented, some information responses will be retrieved by from the Module. Otherwise, the
Module will report “ERROR” or “+CME ERROR” or “+CMS ERROR” to Customer Application.
Information responses start and end with <CR><LF>, i.e. the format of information responses is
“<CR><LF><response><CR><LF>”. Inside information responses, there may be one or more <CR><LF>.
Throughout this document, only the responses are presented, and <CR><LF> are intentionally omitted.

Description
Smart Machine Smart Decision
SIM7500_SIM7600 Series_AT Command Manual_V1.10 2018-10-08
79
Write command forces an attempt to select and register the GSM/UMTS network operator. <mode>
is used to select whether the selection is done automatically by the ME or is forced by this
command to operator <oper> (it shall be given in format <format>). If the selected operator is not
available, no other operator shall be selected (except <mode>
=4). The selected operator name
format shall apply to further read commands (AT +COPS?) also. <mode>=2 forces an attempt to
deregister from the network. The selected mode affects to all further network registration (e.g. after
<mode>=2, ME shall be unregistered until <mode>=0 or 1 is selected).
Read command returns the current mode and the currently selected operator. If no operator is
selected, <format> and <oper> are omitted.
Test command returns a list of quadruplets, each representing an operator present in the network.
Quadruplet consists of an integer indicating the availability of the operator <stat>, long and short
alphanumeric format of the name of the operator, and numeric format representation of the operator.
Any of the formats may be unavailable and should then be an empty field. The list of operators shall
be in order: home network, networks referenced in SIM, and other networks.
It is recommended (although optional) that after the operator list TA returns lists of supported
<mode>s and <format>s. These lists shall be delimited from the operator list by two commas.
When executing AT+COPS=? , any input from serial port will stop this command.

This command refers to supplementary service related network initiated notifications. The set
command enables/disables the presentation of notification result codes from TA to TE.
When <n>
=1 and a supplementary service notification is received after a mobile originated call
setup, intermediate result code +CSSI: <code1>[,<index>] is sent to TE before any other MO call
setup result codes presented in the present document. When several different <code1>s are received
from the network, each of them shall have its own +CSSI result code.
When <m>
=1 and a supplementary service notification is received during a mobile terminated call
setup or dur
ing a call, or when a forward check supplementary service notification is received,
unsolicited result code +CSSU: <code2>[,<index>[,<number>,<type>[,<subaddr>,<satype>
]]] is
sent to TE. In case of MT call setup, result code is sent after every +CLIP resul
t code (refer
command "Calling line identification presentation +CLIP") and when several different <code2>s
are received from the network, each of them shall have its own +CSSU result code.
NOTE: This command not supported in CDMA/HDR mode.

5.16 AT+CEREG EPS network registration status
Description
The set command controls the presentation of an unsolicited result code +CEREG: <stat> when
<n>=1 and there is a change in the MT's EPS network registration status in E-
UTRAN, or
unsolicited result code +CEREG: <stat>[,<tac>,<ci>[,<AcT>]] when <n>=2 and there is a change
of the network cell in E-UTRAN; in this latest case <AcT>, <tac> and <ci> are sent o
nly if
available.
NOTE 1: If the EPS MT in GERAN/UTRAN/E-UTRAN also supports circuit mode services and/or
GPRS services, the +CREG command and +CREG
: result codes and/or the +CGREG command
and +CGREG: result codes apply to the registration status and locat
ion information for those
services.
The read command returns the status of result code presentation and an integer <stat> which shows
whether the network has currently indicated the registration of the MT. Location information
elements <tac>, <ci> and <AcT>, if available, are returned only when <n>=2 and MT is registered
in the network.

This command allows the control the following call related services:
1. A call can be temporarily disconnected from the ME but the connection is retained by the
network.
2. Multiparty conversation (conference calls).
3. The served subscriber who has two calls (one held and the other either active or alerting)
can connect the other parties and release the served subscriber's own connection.
Calls can be put on hold, recovered, released, added to conversation, and transferred. This is
based on the GSM/UMTS supplementary services.

6.13 AT+CLIR Calling line identification restriction
Description
This command refers to CLIR-
service that allows a calling subscriber to enable or disable the
presentation of the CLI to the called party when originating a call.
Write command overrides the CLIR subscription (default is restricted or allowed) when temporary
mode is provisioned as a default adjustment for all following outgoing calls. This adjustment can be
revoked by using the opposite command.. If this command is used by a subscriber without
provision of CLIR in permanent mode the network will act.
Read command gives the default adjustment for all outgoing calls (given in <n>), and also triggers
an interrogation of the provision status of the CLIR service (given in <m>).
Test command returns values supported as a compound value.

9.6 AT+CGTFT Traffic Flow Template
Description
This command allows the TE to specify a Packet Filter - PF for a Traffic Flow Template - TFT that
is used in the GGSN in UMTS/GPRS and Packet GW in EPS for routing of packets onto different
QoS flows towards the TE. The concept is further described in the 3GPP TS 23.060
[47]. A TFT
consists of from one and up to 16 Packet Filters, each identified by a unique <packet filter
identifier>. A Packet Filter also has an <evaluation precedence index> that is unique within all TFTs
associated with all PDP contexts that are associated with the same PDP address.

13 AT Commands for File System
The file system is used to store files in a hierarchical (tree) structure, and there are some definitions and
conventions to use the Module.
Local storage space is mapped to “C:”, “D:” for TF card, “E:” for multimedia.
NOTE: General rules for naming (both directories and files):
1 The length of actual fully qualified names of directories and files can not exceed 254.
2 Directory and file names can not include the following characters:
\ : * ? “ < > | , ;
3 Between directory name and file/directory name, use character “/” as list separator, so it can not
appear in directory name or file name.
4 The first character of names must be a letter or a numeral or underline, and the last character can
not be period “.” and oblique “/”.
13.1 AT+FSCD Select directory as current directory

1. Output of NMEA sentences is automatic; no control via AT commands is provided. At
present the module only supports standalone mode. If executing AT+CGPS=1, the GPS
session will choose cold or hot start automatically.
2. UE-based and UE-assisted mode depend on URL (AT+CGPSURL). When UE-based
mode fails, it will switch standalone mode.
3. UE-assisted mode is singly fixed. Standalone and UE-based mode is consecutively
fixed.
4. After the GPS closed, it should to wait about 2s~30s for start again. Reason：If the
signal conditions are right (strong enough signals to allow ephemeris demodulation) or
ephemeris demodulation is on going, sometimes MGP will stay on longer in order to
demodulate more ephemeris.
This will help the engine provide faster TTFF and
possibly better yield later (up to 2 hours), because it has the benefit of more ephemeris
available.
