Identifier for an elementary data file on SIM, if used by <command>.
Parameters to be passed on by the Multi-Tech wireless modem to the SIM.
0...255
Information which shall be written to the SIM (hexadecimal character format).
Contains the directory path of an elementary file on a UICC in hexadecimal format (e.g.
"7F105F50"). Up to 3 Dedicated Files (DFs) can be listed.
The <pathId> parameter is applicable only to UICCs.
Some types of UICCs may have Dedicated Files which are not unique, because the same FileID is
allocated to several applications on the UICC and this way used twice or even more times.
Therefore, to access UICC files of SIM applications please use the optional parameter <pathId>.
UICC files of USIM applications are accessible without any need for the <pathId> parameter.
AT+CRSM offers easy access of the Elementary Files on the SIM. Access to the SIM
database is restricted to the commands which are listed at <command>. However, additional
SIM commands are available via AT^SXSM.
All parameters of AT+CRSM are used as specified by GSM 11.11. The Multi-Tech wireless
modem handles internally all required SIM interface locking and file selection routines.
As response to the command, the Multi-Tech wireless modem sends the actual SIM
information parameters and response data. Error result code “+CME ERROR” may be
returned if the command cannot be passed to the SIM; e.g., if the SIM is not inserted.
However, failure in the execution of the command in the SIM is reported in <sw1> and
<sw2> parameters.
Please beware of possible changes to Elementary Files by the network at any time.
