+CCHO – Open Logical Channel
AT+CCHO=<dfname
>
Execution of the command causes the MT to return <sessionid> to allow the TE to
identify a channel that is being allocated by the UICC, which is attached to ME.
Parameter
<dfname>
: all selectable applications in the UICC are referenced by a DF name
coded on 1 to 16 bytes.
+CCHO: <sessionid>
where:
<sessionid > : A session ID to be used in order to target a specific application. It is
to be used when sending commands with +CGLA commands.
AT+CCHO=?
Test command returns the
OK
result code

+CCHC – Close Logical Channel
AT+CCHC=<
sessionid>
This command asks the ME to close a communication session with the UICC. The
ME shall close the previously opened logical channel. The TE will no longer be
able to send commands on this logical channel. The UICC will close the logical
channel when receiving this command.
Parameter
< sessionid >
: A session ID to be used in order to target a specific application.
AT+CCHC=?

+CGLA – Generic UICC Logical Channel Access
AT+CGLA=<sessioni
d>,<length>,<comma
nd>
This command allows a direct control of the UICC by a distant application on the

Set command transmits to the MT the <command> it then shall send as it is to the
UICC The <response> is Returned in the same manner to the TE
Parameters:
<
sessionid
> integer type; this is the identifier of the session to be used in order to
send the APDU commands to the UICC. It is manadatory in order to send
commands to the UICC when targeting applications on the UICC using a logical
channel other than the default channel (channel "0").
<
length
> integer type; length of the characters that are sent to TE in <command>
<
command
> command passed on by MT to SIM in hex format code (e.g.
