5.8AT^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 Customer SIM Lock is protected by two different passwords:

•<password> = Network Personalisation password "CM" defined with AT^SPWD and necessary for program- ming the Customer SIM Lock with AT^SCSL.

•<PUK> = Lock/Unlock Code defined with AT^SCSL and used to set the Customer SIM Lock with AT^SCSL. Also used to deactivate a given lock or activate a new one via AT+CLCK or AT^SLCK. The PUK may be pro- visioned to the end user.

The AT^SCSL write command serves to configure a Customer SIM Lock and to query the current settings.
