First
Enter the Setup menu
by pressing »MENU«
Select »Security«
Entering the Security menu gives
you different possibilities of pre-
venting misuse of your SIM card
and your telephone, e.g. if your
phone is lost or stolen.
PIN code
Activate PIN
Select whether your
PIN code should be on or off. The
PIN code is a 4 to 8 digit code
which must be entered each time
you switch on your phone.
Change PIN
Change your PIN
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.
