Phone security

•ACCESS CODES

•Security code—This code, supplied with the phone, protects your phone against unauthorized use. The preset code is 12345. See “Security” on page 62 for more information.

•PIN code—This code, supplied with the SIM card, protects the card against unauthorized use. Set on the PIN code request in the Security settings menu (see “Security” on page 62 for more information), so that the code is requested each time the phone is switched on. If you enter an incorrect PIN code three times in succession, the SIM card is blocked. You must enter the PUK code to unblock the SIM card and set a new PIN code.

•PIN2 code—This code is supplied with some SIM cards and is required to access certain services, such as charging unit counters. If you enter an incorrect PIN2 code three times in succession, PIN2 code blocked appears in the display and you will be asked for the PUK2 code.

You can change the security code, PIN code and PIN2 code in Access codes in the Security settings menu. See “Security” on page 62 for more information. Keep the new codes secret and in a safe place, separate from your phone.

•PUK and PUK2 codes—These codes may be supplied with the SIM card. For more information, contact your service provider.

•Call restriction password (4 digits)—The restriction password is needed when using the Call restrictions. See “Security” on page 62 for more information. You can obtain the password from your service provider.

•CLOSED USER GROUPS

This network service specifies the group of people whom you can call and who can call you. Default resets the phone to use a user group that the SIM card owner has agreed upon with the service provider. When calls are limited to closed user groups, calls still may be possible to the official emergency number programmed into your phone.
