A password can protect your phone and help avoid 

illegal use. If your phone is password protected, you will 

have to enter the correct password when the phone is 

turned on.
•   For a new phone, the protection function is not 

activated by default, and the default password  

is 0000.

•   From idle mode, select Menu > Settings > 

Security > Activate security codes > Phone 

lock code to start or stop password protection.

•   From idle mode, select Menu > Settings > 

Security > Change security > Phone lock code 

to change the phone’s password. It is suggested 

that you change the password to something you will 

easily remember.

•   Please remember the password you set. Without it 

your phone cannot be used normally and you will 

need to contact your service provider to unlock it. 

•   Contact your service provider for more information.

A PIN code is the personal identification code used 

by the SIM card. Its purpose is to help you avoid 

illegal use of your SIM card. The correct PIN code 

should be entered when the new phone is first turned 

on, otherwise the phone will only be able to make 

emergency calls.
•   For a new card, the default code is supplied by the 

service provider.

•   From idle mode, select Menu > Settings > 

Security > Activate security codes > PIN code 

to enable or disable the PIN code.

•   From idle mode, select Menu > Settings > 

Security > Change security > PIN code to 

change the PIN code.

•   If you enter the wrong PIN code three times in a 

row, the phone will lock the SIM card and prompt 

you to enter a PUK code to unlock it.

•   If you change the PIN code, be sure to remember the 

new number.

•   PIN2 is needed for some settings. Use the same 

procedure as for the PIN code.
