+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 GSM 11.11 version 8.7.0. As response to the command, the
G24 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.
