Multi-Tech Systems, Inc. Wireless GSM/GPRS AT Commands (Document Number S000293I) 

142 

In order to allow the customer application to identify the pro-active command sent via SIM Toolkit, a mechanism of 
unsolicited SIM Toolkit indications (+STIN) is implemented. 

Syntax: AT+STIN: <CmdType> 

Option: 

<CmdType>

Indicates that a ‘Setup Menu’ pro-active command has been sent from the SIM.

Indicates that a ‘Display Text’ pro-active command has been sent from the SIM. 

2 

Indicates that a ‘Get Inkey’ pro-active command has been sent from the SIM. 

3 

Indicates that a ‘Get Input’ pro-active command has been sent from the SIM. 

4 

Indicates that a ‘Setup Call’ pro-active command has been sent from the SIM. 

5 

Indicates that a ‘Play Tone’ pro-active command has been sent from the SIM. (*)

94 

An “SMS-PP Download” failed due to SIM ERROR 

98 

Indicates the timeout when no response from user. 

99 

Indicates that a 

“End Session” has been sent from the SIM. 

(*) if the automatic response parameter is activated, this indication is followed by the corresponding +STGI 
response. 

If the customer application needs to exchange a SIM Toolkit message directly with the SIM card, the second 
indication (+STRIL) gives the full command string provided by the SIM.  
Values:   

<CmdTreated>

The command must be treated by the application 

The is already treated by the modem

<Command string> string type: SIM command string in hexadecimal format. 

Syntax:  

+STRIL: <CmdTreated>,<Command string> 

 

The last SIM Toolkit indication sent by the SIM can be requested by the 

AT+STIN? command. This command is 

only usable between the sending of the STIN indication by the SIM (Step 2, Messages exchanged during a SIM 
Toolkit operation) and the response of the user with the +STGI command (Step 3). 
Syntax: Command syntax: AT+STIN?
