Description
By using AT+CRSM instead of Generic SIM Access AT+CSIM, TE application has easier but
more limited access to the SIM database.
Write command transmits to the MT the SIM <command> and its required parameters. MT handles
internally all SIM-MT interface locking and file selection routines. As response to the command,
MT sends the actual SIM information parameters and response data. MT error result code +CME
ERROR
may be returned when the command cannot be passed to the SIM, but failure in the
execution of the command in the SIM is reported in <sw1> and <sw2> parameters.
