code.

Change PIN2

Change your PIN2 code (used on some SIM cards to access special functions).

SIM lock

Link your telephone and your SIM card together by activating the SIM lock. You will be asked to enter a 6 to 16 digit code of your own choice.

This means that if for instance your phone is stolen, it cannot be used together with another SIM card.

Network password

Change your network password

(used if you subscribe to a call bar-

ring service).

Facts & Tips

If you enter an invalid PIN code three times, your SIM card will be blocked, and to unblock it you have to enter the PUK code supplied by your network operator. This procedure prevents unauthorised persons from working out your PIN code by repeat- edly entering different combinations of numbers.

For your own sake, remember to write down your SIM lock code to be able to deactivate the lock at a later time. You have 10 attempts before the phone is blocked.

The phone will inform you how many tries you have left before the SIM card is blocked. If you enter an invalid PUK code 10 times, your SIM card will be permanently blocked and you have to contact your network operator.

Encryption indication

Get a warning in the display and a sound alarm, if you connect to a network which does not support encryption.

Fixed dialling

Select whether you want the fixed dialing function to be on or off (only available if you have defined and stored numbers in the fixed dialing phone book (p. 21).

If you have selected »Fixed dialling on«, you will have access only to the numbers stored in the fixed dialing phone book when you

press .

Your plain numbers phone book will not be visible in the List menu and can thus not be accessed. Of course, it remains on the SIM card and can be accessed again by selecting »Fixed dialling off«.

Your address book will be visible in the List menu, but if you wish to call a number from the address

book which is not stored in the fixed dialing phone book you will be informed that it is not possible to make the call

Barred dialling

Select whether you want the barred dialing function to be on or off (only available if you have defined and stored numbers in the barred dialing phone book (p. 22).

Facts & Tips

Encryption means that the network encrypts conversations to make it dif- ficult for unauthorised persons to lis- ten in on them.

Contact your network operator for further information on PUK2 and PIN2 codes.
