.
When calls are limited to closed user groups, calls may be possible to the official emergency number programmed into your
device.
Define the following settings:
•
PIN code request
— Select
On
to request that the PIN code is entered each time the device is switched on. This setting cannot
be changed if the device is switched off. Some SIM cards do not allow turning off the PIN code request.
•
PIN code
— Change the PIN code. The PIN code must be 4 to 8 numbers long. The PIN code protects your SIM card against
unauthorized use and is provided with the SIM card. After three consecutive incorrect 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.
•
PIN2 code
— Change the PIN2 code. The PIN2 code must be 4 to 8 numbers long. The PIN2 code is required to access some
functions of the device and is provided with the SIM card. After three consecutive incorrect PIN2 code entries, the PIN2 code
is blocked, and you need to use the PUK2 code to unblock it 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 4-255 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.
•
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. The maximum number of characters allowed is 8. Using more than 8 characters could
prevent unlocking the memory card and require reformatting it. If reformatting the memory card is required, all information
on the card will be lost.
•
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.
