Phone and SIM
You can change the following codes: lock code, PIN code, and PIN2 code. These
codes can only include the numbers from 0 to 9.
Avoid using access codes similar to emergency numbers, to prevent accidental
dialing of the emergency number.
To set the security settings, select Menu > Tools > Settings > Security > Phone
and SIM and from the following options:
Code in use — to select the active code, PIN or UPIN, for the active USIM. This is
shown only if the active USIM supports UPIN, and the UPIN is not rejected.
PIN code request (or UPIN code request) — to set the phone to request the code
each time the phone is switched on. Some SIM cards may not allow the PIN code
request to be turned Off. If you select Code in use > UPIN, UPIN code request is
shown instead.
PIN code (or UPIN code) /PIN2 code /Lock code — to change the codes
Autolock period — to set a time-out after which the phone is automatically
locked. To use the phone again, you need to enter the correct lock code. To turn off
the autolock period, select None.
Lock if SIM changed — to set the phone to prompt for the lock code when an
unknown, new SIM card is inserted into your phone. The phone keeps a list of SIM
cards that are recognized as the owner cards.
Closed user group (network service) — to specify a group of people whom you can
call and who can call you. For more information, contact your network operator or
service provider. To activate the default group agreed on with the network
operator, select Default. If you want to use another group (you need to know the
group index number), select On.
Confirm SIM services (network service) — to set the phone to display confirmation
messages when you use a SIM card service
