Release 6

<response> : response to the command passed on by the SIM to the MT in the format as described in

GSM 51.011 [28] (hexadecimal character format; refer +CSCS)

Implementation

Optional.

Command

Possible response(s)

+CRSM: <sw1>,<sw2>[,<response>]

+CME ERROR: <err>

+CRSM=?

Description

By using this command instead of Generic SIM Access +CSIM TE application has easier but more limited access to the

SIM database. Set 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. Refer to subclause 9.2 for <err> values.

Coordination of command requests to SIM and the ones issued by GSM/UMTS application inside the MT is

implementation dependent. However the TE should be aware of the precedence of the GSM/UMTS application

commands to the TE commands.

Defined values

<command> (command passed on by the MT to the SIM; refer GSM 51.011 [28]):

176 READ BINARY

178 READ RECORD

192 GET RESPONSE

214 UPDATE BINARY

220 UPDATE RECORD

242 STATUS

all other values are reserved

NOTE 1: The MT internally executes all commands necessary for selecting the desired file, before performing the

actual command.

<fileid>: integer type; this is the identifier of a elementary datafile on SIM. Mandatory for every command

except STATUS

NOTE 2: The range of valid file identifiers depends on the actual SIM and is defined in GSM 51.011 [28]. Optional

files may not be present at all.

<P1>, <P2>, <P3>: integer type; parameters passed on by the MT to the SIM. These parameters are mandatory for

every command, except GET RESPONSE and STATUS. The values are described in GSM 51.011 [28]

<data>: information which shall be written to the SIM (hexadecimal character format; refer +CSCS)

<sw1>, <sw2>: integer type; information from the SIM about the execution of the actual command. These

parameters are delivered to the TE in both cases, on successful or failed execution of the command
