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, PIN2 code, and Lock code — You can
change the PIN code, PIN2 code, and lock code.
These codes can only include numbers from 0 to 9.
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 130 you forget the
lock code, contact a Nokia Care point or your service
provider.
● 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 the
autolock period, select None.
● Lock if SIM card changed — You can 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 — You can specify a group of
people to whom you can call and who can call you
(network service).
● Confirm SIM services — You can set the device to
display confirmation messages when you are using
a SIM card service (network service).
In the offline or flight profiles, you may need to unlock
the device and change to the calling profile before
making a call.
When calls are limited to closed user groups, calls may
be possible to the official emergency number
programmed into your device.
