14.4 AT^SXSM Extended SIM Access
AT^SXSM extends AT+CRSM with additional SIM commands.
All parameters of AT^SXSM are used as specified by GSM 11.11 [24]. AC75 handles internally all required SIM
interface locking and file selection routines.
AC75 may return error result code "+CME ERROR" if the command cannot be passed to the SIM, e.g. if no SIM
is inserted. However, errors related to SIM action are reported in <sw1> and <sw2> parameters as defined in
GSM 11.11 [24].
