Motorola G24 用户手册

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.

Set command transmits the 
SIM <command> and its 
required parameters to the ME. 
ME sends the actual SIM infor-
mation parameters and 
response data.

The test command returns the 
possible ranges of CRSM 
parameters.
