Parameter
<fac> Phone security locks set by client or factory:
“SC” SIM (lock SIM cards). SIM requests password upon ME power-
up and when this lock command is issued. "SC" lock is protected
with SIM PIN1. The number can be modified with AT+CPWD or
AT^SPWD. See examples in Chapter 4.21.2 for further explana-
tions.
“PS” Phone locked to SIM card. ME requests passwor d when other
than current SIM card is inserted.
If set individually by the client, the password for the "PS" lock
can be specified with AT+CPWD or AT^SPWD.
If set by factory (e.g. for a prepaid mobile), the password is sup-
plied by the provider or operator.
“FD” SIM fixed dialling memory: If the mobile is lock ed to "FD", only
the phone numbers stored to the "FD" memory can be dialled
(depending on the SIM card, usually up to 7 numbers). PIN2 is
requested as <passwd>.
"CS" Keypad lock (not supported since keypad cannot be directly
connected to the GSM engine)
Note: Primarily intended for the client to take safety precautions, "SC",
"PS" and "FD" can be configured individually. "PS" m ay also be
factory set.
"PS" lock is frequently referred to as "phone lock", or "devic e
lock". Accordingly, the password may be called "phone code" or
"device code". The "PS" password is not associated with the
PUK of the SIM card. If incorrectly entered three times, the Mas-
ter Phone Code is required to lift the lock. Once the Master
Phone Code has been acctepted, the mobile is operational, and
the "PS" lock is no longer active. If needed it must be set once
again. See Chapter 4.35.1 and examples below for further de-
tails.
