Phone Code
The phone code is used to protect your phone from
unauthorized use and restore factory settings. If the
phone lock function is enabled, you need to enter the
phone code every time you power the phone on. By
default, the phone lock function is disabled.
The phone code is set to 0000 by default. You can select
Menu > Settings > Security Settings > Change
Security Code > Change Phone Code to change the
phone code into any numeric string of four to eight
digits.
Do remember your phone code. If you forget the phone
code, contact the service center.
PIN and PUK
The personal identification number (PIN) protects your
SIM card from unauthorized use. The PIN unblocking
key (PUK) can unlock the blocked PIN. Both PIN and PUK
are delivered with the SIM card. For details, consult your
service provider.
If you enter wrong PINs for a specified number of times
consecutively, the phone asks you to enter the PUK.
If you enter wrong PUKs for a specified number of times
consecutively, the SIM card is invalidated permanently.
Contact your service provider for a new one.
Locking the Keypad
In standby mode, press and hold for about 3s to lock
the keypad. When the keypad is locked, you can press
to answer an incoming call or make emergency
calls.
