5.4 AT^SCSL Customer SIM Lock

AT^SCSL is a Siemens defined command especially designed to manage the Customer SIM Lock feature. This

feature allows application manufacturers to lock a mobile to specific operators by activating a Network Person-

alization ("PN"). If the lock is enabled the mobile will accept only SIM cards from the given operators.

The lock is activated by specifying the mobile country codes and mobile networks codes on command line.

The Customer SIM Lock feature is protected by depersonalization key.
