+CME ERROR: <err>
Parameter
<fac> Phone security locks:
“SC” SIM (lock SIM cards). SIM requests password upon ME power-
up and when this lock command is issued.
<password>: SIM PIN1. The password can be modified with
AT+CPWD or AT^SPWD (see Chapters 4.38 and 7.42).
“PS” Phone locked to SIM card. ME requests password when other
than current SIM card is inserted.
<password>: User defined password. It is needed before the first
use of <fac>”PS and, therefore, must first be specified with
AT+CPWD or AT^SPWD.
“FD” SIM fixed dialing memory: If the mobile is locked to "FD", only
the phone numbers stored to the "FD" memory can be dialed
(depending on the SIM card, usually up to 7 numbers).
<password>: SIM PIN2 (or equivalent authorisation via
AT+CPIN2, see Chapter 4.36.)
If a lock on the SIM fixed dialing memory is active, call related
Supplementary Services such as call barring, call waiting or call
forwarding cannot be accessed via AT command. The response
will be “ +CME ERROR: call barred”. In this case, access to call
related Supplementary Services is possible only if the corre-
sponding public MMI *# code is stored in the fixed dialing num-
ber phone book, or by deactivation of the SIM fixed dialing facility
lock)
Note: "PS" lock is frequently referred to as "phone lock", or "device
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. This is an 8-digit de-
vice code associated to the IMEI number of the mobile which can
only by obtained from the manufacturer of the TC35i module.
Once the Master Phone Code has been acctepted, the mobile is
operational, and the "PS" lock is no longer active. See Chapter
4.35.1 and examples below for further details.
