Use this command when you want to
· change PIN1 or PIN2,
· change the password supplied from your provider for call barring,
· set individual phone security passwords,
· enter the unblocking key (e.g. PUK. PUK2, Master Phone Code) to restore a disabled password.
See Chapters 4.21 and 7.15 for more information on the various lock features. The AT^SPWD
command is a Siemens defined command equivalent to AT+CPWD. See Chapter 7.42.

"PS" Phone locked to SIM (device code). Password is user defined
and must be set before the “PS” lock can be activated with
AT+CLCK or AT^SLCK.
Note: SIM PIN1 and SIM PIN2 are each assigned a PUK to unblock a
disabled PIN.
The "PS" password, however, is never associated with a PUK. If
it is incorrectly entered three times, the Master Phone Code is
required. See Chapter 4.35.1
