PIN code request

PIN code

be 4 to 8 numbers long. The PIN code protects your
SIM card against unauthorized use and is provided

PIN code entries, the PIN code is blocked, and you
need to use the PUK code to unblock it before you
can use the SIM card again.

must be 4 to 8 numbers long. The PIN2 code is
required to access some functions of the device and

before you can use the SIM card again.

Autolock period
— Set a time-out after which the
device is automatically locked and can be used only
if the correct lock code is entered. Enter a number for
the time-out in minutes, or select
None
to turn off
the autolock period. When the device is locked, you
can still answer incoming calls and calls may still be
possible to the official emergency number
programmed into your device.
•
Lock code
— The new code can be 4-256 characters
long. Both alphabets and digits can be used, and
both uppercase and lowercase alphabets are
possible. The device notifies you if the lock code is
not properly formatted. The device remembers the
previously used lock codes and prevents you from
using the same lock code several times.
•
Lock if SIM changed
— Set the device to ask for the
lock code when an unknown, new SIM card is
inserted into your device. The device maintains a list
of SIM cards that are recognized as the owner’s cards.
•
Allow remote lock
— If you set this option on, you
can lock the device by sending a predefined text
message from another phone. When you set this
option on, you need to enter the remote lock
message and confirm the message. The message
must be at least 5 characters long.
•
Closed user group
(network service) — Specify a
group of people to whom you can call and who can
call you.
•
Confirm SIM services
(network service) — Set the
device to display confirmation messages when you
are using a SIM card service.
