<response> is the response data of
EFiccid. For details about <response>,
refer to the
ETSI TS 102.221
protocol.

<status> indicates the current directory

Notes:
To read or update a file, appropriate commands must be used according to the file's
structure type (for details, refer to the description of file properties in the
3GPP TS 31.102
protocol). For transparent structure files, use 176 (Read Binary) and 214 (Update Binary).
For linear fixed structure files, use 178 (Read Record) and 220 (Update Record).
If <pathid> is not contained in the command, the module will prefer to access the files with
the same FID in the current directory.
Files can be accessed only when the access criteria are met. Otherwise the SIM card will
return PSWs indicating that the access authentication failed. If an EF file's read privilege is
PIN protected and the module does not have the PIN authenticated, PSWs indicating that
the access authentication failed will be returned after the
CRSM
command is used to read
the EF file.
To use the
CRSM
command to access the file content on the SIM card, the parameters
contained in the command must strictly meet the requirements in the
ETSI TS 102.221
and
3GPP TS 31.102
. For detailed requirements, refer to the
ETSI TS.102.221
and
3GPP TS
31.102.
