AT+CLCK can be used to lock, unlock or interrogate a network or ME <facility>. The command can be
aborted when network facilities are being set or interrogated.
Syntax
Parameter Description
Phon
e security locks set by client or factory
Primarily intended for the client to take safety precautions, "SC", "PS" and "FD" can be configured individually.
"PS" may also be factory set.
Parameter <class> is not applicable to security locks.
See examples below for further details.
“SC“ SIM (lock SIM cards)
SIM requests password upon ME power-up and when this lock command is
issued.
<password>: SIM PIN1.
“PS“ Phone locked to SIM card
ME requests password when other than current SIM card is inserted.
"PS" lock is frequently referred to as "phone lock", or "device lock". Accord-
ingly, 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 Master Phone Code is required to lift the lock. This is an 8-digit
device code associated to the IMEI number of the mobile which can only be
obtained from the manufacturer of the module. 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has been acctepted, the mobile is operational, and the "PS" lock is no longer
active.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.
