Restricted UICC Logical Channel CRLA
By using this command instead of Generic UICC Access +CGLA TE application has easier but more limited
access to the UICC database. Set command transmits to the MT the UICC <command> and its required
parameters. MT handles internally all UICC-MT interface locking and file selection routines. As response to the
command, MT sends the actual UICC information parameters and response data. MT error result code +CME
ERROR may be returned when the command cannot be passed to the UICC, but failure in the execution of the
command in the UICC is reported in <sw1> and <sw2> parameters.
