SIM lock
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 6 to 16-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 be-
fore the phone is blocked.
How to change password
If you subscribe to a call barring service your
network operator will have supplied you with a
4-digit password. If you want to change this,
select Network password in the Security
menu.
Encryption indication
If you connect to a network which does not
support encryption, you will get a warning in the
display when trying to make a call. You have the
option of turning off this network warning by
selecting Encryption indication off
in the security menu.
Line lock
If you have Alternate Line Service on your phone
you can restrict the outgoing use to only one of
these lines. Select Line lock on in the
security menu and enter a 4 to 8 digit lock code
of your own choice. To shift back to the other line
you have to enter this code.
Call timers and charge
Your telephone can display the actual duration
and cost of an ongoing conversation if you so
wish. It can also show you the duration and cost
of the last call and all calls made with your SIM
card since the timer was last reset. However, the
call charge feature must be supported by your
network.
In order to be able to see the cost in the display
you have to enter a unit price and the actual cur-
rency. You can also enter a maximum call charge
limit, so that when this maximum has been
reached no more phone calls can be made. The
telephone will inform you about the remaining
call charge balance.
To enter or change call charge and currency you
will be requested to enter your PIN2 code.

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.
Some SIM cards use a PIN2 code for accessing
special functions. Contact your network operator
for further information on PUK2 and PIN2 code.
