The AT commands described in this chapter are related to the Subscriber Identity Module (SIM) connected to

TC63. 

 Note:

If using data from the SIM please bear in mind that the content of all Elementary Files is subject to change at any

moment!

This is true because the network can change the SIM's data in the background via the SIM Application Toolkit

(SAT) procedure "Data download to SIM". For a detailed description please refer to GSM 11.14, 

. 

To get informed that changing Elementary Files has taken place the TA needs to hook to the SAT Proactive Com-

mand "REFRESH". To achieve this, the AT command interface of SAT, i.e. Remote-SAT, needs to be activated.

An overview is given at Chapter 

, additional information is available

with the document "Remote-SAT User Guide" 

 offers easy access of the Elementary Files on the SIM. Access to the SIM database is restricted to the

commands which are listed at 

. However, additional SIM commands are available via 

. 

All parameters of 

 are used as specified by GSM 11.11 

. TC63 handles internally all required SIM

interface locking and file selection routines. 

As response to the command, the TC63 sends the actual SIM information parameters and response data. Error

result code "+CME ERROR" may be returned if the command cannot be passed to the SIM, e.g. if the SIM is not

inserted. However, failure in the execution of the command in the SIM is reported in 

 and 

 param-

eters. 

 requires PIN authentication. However, using 

 "READ

RECORD" is possible before PIN authentication and if the SIM is blocked (state after three failed PIN authenti-

cation attempts) to access the contents of the following Elementary Files: 

Please beware of possible changes to Elementary Files by the network at any time, refer Chapter
