AT Commands Reference
4.9.1.5
+CLCK, Facility Lock
This command locks, unlocks or interrogates a g20 or a network facility <fac> (any kind of call barring program). A password
is mandatory for performing locking and unlocking actions, but not for querying. The features of the g20 that are affected by
this are the keypad power-up operation and fixed dialing list. When querying the status of a single call barring program
<mode>=2, the <status> for each call type will be returned.
For <fac>="SC", SIM Card PIN setting and for <fac>="FD", SIM Fixed Dialing memory setting, the <class> is irrelevant (For
more information about <class>, refer to +CLCK Parameters). The <passwd> for "sc" is SIM PIN, and for "fd" it is SIM PIN2.
