Select from the following:
PIN code request — When active, the code is requested each time the device is
switched on. Deactivating the PIN code request may not be allowed by some SIM cards.
PIN code andPIN2 code — Change the PIN and PIN2 code. These codes can only include
numbers. Avoid using access codes similar to the emergency numbers to prevent
accidental dialling of the emergency number. If you forget the PIN or PIN2 code, contact
your service provider. If you forget the lock code, contact a Nokia Care point or your
service provider.
Lock code — The lock code is used to unlock the device. To avoid unauthorised use of
your device, change the lock code. The preset code is 12345. The new code can be 4-255
characters long. Alphanumeric characters and both uppercase and lowercase characters
can be used. The device notifies you if the lock code is not properly formatted. Keep the
new code secret and separate from your device.
Phone autolock period — To avoid unauthorised use, you can set a time-out after
which the device automatically locks. A locked device cannot be used until the correct
lock code is entered. To turn off autolock, select None.
Lock if SIM card changed — Set the device to ask for the lock code when an unknown
SIM card is inserted into your device. The device maintains a list of SIM cards that are
recognised as the owner's cards.
Remote phone locking — Enable or disable remote lock.
Closed user group — Specify a group of people to whom you can call and who can call
you (network service).
Confirm SIM services — Set the device to display confirmation messages when you
are using a SIM card service (network service).
