PIN Codes

A PIN code is the personal identification code used by the SIM card. Its purpose is to 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.

Notes:

If you change the PIN code, please remember the new number.

PIN2 is needed for some settings. Use the same procedure as for the PIN code.

PUK Codes

A PUK code is the unlock code for the SIM card. When the SIM card is locked, you have to enter the correct PUK code and then enter the new PIN code. The SIM card can then be used normally.

•  A PUK code may be supplied with a new card. Contact your service provider for more information.

•  A PUK code can only be entered 10 times in a row. If you enter the wrong PUK code more than 10 times, the SIM card will be locked indefinitely.

Note: If a PUK code is supplied with the new card, please store it safely.
