Encryption indication
Get a warning in your display if you
connect to a network which does
not support encryption.
Line lock
If you have Alternate Line Service
on your SIM card you can restrict
the outgoing use to only one of
these lines.
Activate the line lock in this sub
menu and enter a 4 to 8 digit lock
code of your own choice. To shift
back to the other line you have to
re-enter this code.
Facts & Tips
• 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.
• 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 unau-
thorised persons 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 must
contact your network operator.
• Contact your network operator for
further information on PUK2 and PIN2
codes.
• Encryption means that the network
encrypts the conversations to make it
difficult for unauthorised persons to
listen in on them.

card.
