4.1.8 +CRSM, Restricted SIM Access
This command provides limited access to the Elementary Files on the SIM. Access to the SIM database is
restricted to the commands which are listed at <command>. All parameters of AT+CRSM are used as
specified by 3GPP TS 51.011(2G) and TS 31.101(3G). As response to the command, the Modem sends
the actual SIM information parameters and response data. Error result code "+CME ERROR" may be
returned if the command cannot be transferred to the SIM, e.g. if the SIM is not inserted, or defected, or
PIN1/PUK authentication required, or required input parameters not present. However, failure in the
execution of the command in the SIM is reported in <sw1> and <sw2> parameters.
Some of the AT+CRSM commands require PIN/PIN2 authentication.
