TC63 AT Command Set

14. SIM related Commands

14. SIM related Commands
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, [24].
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 16.,
with the document "Remote-SAT User Guide" [4].
