General commands 17 6615-2220
+CSIM – Generic SIM Access:
Description:
This command allows a direct control of the SIM by a distant application on the TE.
The is sent without any modification to the SIM. In the same manner the
SIM is sent back by the ME as it is.
The user shall then take care of processing SIM information within the frame specified by
GSM as specified in GSM 11.11 (or 3GPP TS 51.011).
If operation mode is not allowed by the ME, +CME ERROR: is returned.
Between two successive +CSIM commands, there is no locking of the interface between
the SIM and the GSM application. Since in this situation some command types and param-
eters can modify wrong SIM's files, some operations, described below, are not allowed for
CSIM command. However, it is possible to process them with the CRSM command.
