SECURITY
PIN code
To prevent misuse of your SIM card, e.g. if it is lost
or stolen, you can select a PIN code to be entered
each time you switch on the phone.
The PIN code is a 4 to 8-digit number of your
own choice, which you can change any time
you like.
If you enter an invalid PIN code three times, your
SIM card will be blocked and to unblock it you
have to enter the PIN Unblocking Key (PUK) code
supplied by your network operator. This proce-
dure prevents unauthorized person from working
out your PIN code by repeatedly entering different
combinations of numbers.
The display 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 to have it un-
blocked.
Some SIM cards (not phase 1) use a PIN2 code for
accessing special functions. Contact your network
operator for further information on PUK2 and
PIN2 codes.

You can link your telephone and your SIM card
together. This means that if, for instance, your
phone is stolen it cannot be used together with
another SIM card. To enable this feature just select
SIM lock on and enter an 8-digit code of
your own choice. For your own sake remember to
write down this code to be able to deactivate the
lock at a later time. You have 10 attempts before
the phone is blocked.
How to change password
If you subscribe to a call barring service your net-
work operator will have supplied you with a 4-
digit password. If you want to change this, select
Network password in the Security menu.
