1 Introduction
1.1 Scope of the document
This document presents the AT Command Set for SIMCom SIM7000 Series, including
SIM7000A, SIM700C, SIM7000E, SIM7000C-N, SIM7000E-N, SIM7000JC and SIM7000G.
1.2 Related documents
You can visit the SIMCom Website using the following link:
http://www.simcomm2m.com
1.3 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;
1.4 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.
The AT Command set implemented by SIM7000 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 SIM7000 Series is powered on and Unsolicited Result
SIMCOM COMFIDENTIAL FILE

Smart Machine Smart Decision
SIM7000 Series_AT Command Manual_V1.03 14 2018-05-08
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:
1.4.1 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.
1.4.2 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.
1.4.3 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.
1.4.4 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 559 characters (counted from the first
command without "AT" or "at" prefix) or 39 AT commands. If the characters entered exceeded
SIMCOM COMFIDENTIAL FILE

Smart Machine Smart Decision
SIM7000 Series_AT Command Manual_V1.03 15 2018-05-08
this number then none of the Command will executed and TA will return "ERROR".
1.4.5 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.
1.5 Supported character sets
The SIM7000 Series AT Command interface defaults to the IRA character set. The SIM7000
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.
1.6 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. SIM7000 Series support both two kinds of flow control.
In Multiplex mode, it is recommended to use the hardware flow control.
1.6.1 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 SIM7000 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
Ensure that any communications software package (e.g. Hyper terminal) uses software flow
control.
SIMCOM COMFIDENTIAL FILE

Smart Machine Smart Decision
SIM7000 Series_AT Command Manual_V1.03 16 2018-05-08
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.
1.6.2 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.
1.7 Definitions
1.7.1 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.
- -: "-" means this AT command doesn’t care the parameter saving mode.
1.7.2 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.

Response
Engineering Mode is designed to allow a field engineer to view and test the
network information received by a handset, when the handset is either in
idle mode or dedicated mode (
that is: with a call active). In each mode, the
engineer is able to view network interaction for the "serving cell" (the cell
the handset is currently registered with) or for the neighboring cells.
TA returns the current engineering mode. The network information
including serving cell and neighboring cells are returned. <cell> carry with
them corresponding network interaction.

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 STA
TUS when it is in single state.
In multi-IP state, the state is in IP STATUS only. 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".
