you different possibilities of pre-

venting misuse of your SIM card

and your telephone, e.g. if your

phone is lost or stolen.

which must be entered each time

you switch on your phone.

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

(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.
