14.7 AT^SXSM Extended SIM Access
AT^SXSM extends AT+CRSM with additional SIM commands.
All parameters of AT^SXSM are used as specified by 3GPP TS 11.11 [14]. BGS2T handles internally all required
SIM interface locking and file selection routines.
BGS2T 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 3GPP TS 11.11 [14].
