modified with
Integer or sum of integers each representing a class of information, i.e. a bearer service, telecommunication ser-
vice or bearer service group as defined in 3GPP TS 22.004

Voice

Class 2 ("data") comprises all those individual data classes between 16 and
128, that are supported both by the network and the MS. This means, a setting
made for class 2 applies to all individual data classes (if supported). In addition,
you can assign a different setting to a specific class. For example, you can acti-
vate Call Forwarding for all data classes, but deactivate it for data class 64,
"dedicated packet access".

Fax
8
SMS
16
Data circuit sync
32
Data circuit async
64
Dedicated packet access
128
Dedicated PAD access
1...[7]...255
Combination of some of the above classes.
For example, the default setting 7 represents the sum of the integers 1, 2 and
4 (voice, data and fax).
The value 255 covers all classes.
If parameter "class" is omitted, the default value 7 is used.
Note
command offers the full range of
parameters according to the 3GPP Technical Spec-
ifications. However, when you attempt to use a service option which is not provisioned or not yet subscribed
to, the setting will not take effect regardless of the response returned.
The responses in these cases vary with the network (for example "OK", "Operation not allowed", "Operation
not supported" etc.). To make sure check the extended error response with
and the lock status with
=2.
Examples
EXAMPLE 1
Lock USIM card (
= "SC")
<status>
(num)
<password>
(str)
<class>
(num)
AT+CLCK="SC",1,"9999"
The "SC" parameter enables or disables the SIM PIN authentication
(PIN 1) when you power up the ME.
OK
USIM card locked. As a result, SIM PIN 1 must be entered to enable ME
to register to the network.
