General commands 17 6615-2220
+CSIM – Generic SIM Access:
Description:
This command allows a direct control of the SIM by a distant application on the TE.
The <command> is sent without any modification to the SIM. In the same manner the
SIM <response> is sent back by the ME as it is.
The user shall then take care of processing SIM information within the frame specified by
GSM as specified in GSM 11.11 (or 3GPP TS 51.011).
If operation mode is not allowed by the ME, +CME ERROR: <error> is returned.
Between two successive +CSIM commands, there is no locking of the interface between
the SIM and the GSM application. Since in this situation some command types and param-
eters can modify wrong SIM's files, some operations, described below, are not allowed for
CSIM command. However, it is possible to process them with the CRSM command.
Syntax:
AT +CSIM=<length>,<command>
Response:
+CSIM: <length>, <response>
+CME ERROR: <err>
Parameters:
<length> Integer type. Length of the characters that are sent to TE in <com-
mand> or <response> (two times the actual length of the command
or response). For command sent to TE, This value must be in the range
[10 – 522 else a CME_ERROR=3 is returned.
<command> Hexadecimal type. Command passed on by the MT to the SIM in the
format as described in GSM 11.11 (or 3GPP TS 51.011) (hexadecimal
character format; refer +CSCS)
Second Byte Value not supported:
Due to the absence of locking, a CME_ERROR=3 is returned for the
following instructions (See CRSM commands):
