14.2 AT+CSIM Generic SIM Access
AT+CSIM allows direct control of the SIM.
Compared to Restricted SIM Access command AT+CRSM, the definition of AT+CSIM allows the ME to take more
control over the SIM interface.
For parameter and SIM result coding please refer to 3GPP TS 11.11 [14].
However, only the following SIM commands are fully supported by AT+CSIM: SELECT, STATUS, READ
BINARY, UPDATE BINARY, READ RECORD, UPDATE RECORD, SEEK, INCREASE and GET RESPONSE.
Other SIM commands will work in conjunction with the SIM but the correct interaction of the SIM with the BGS2T
is not guaranteed.
