AT^SXSM
extends
AT+CRSM
with additional SIM commands.
All parameters of

interface locking and file selection routines.
MC55 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 [21] .
