Phone and SIM card
You can change the following codes: lock code, (U)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.
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, and Lock code — to 
change the codes
Keypad autolock period > User defined — to 
automatically lock the keypad after a defined period of 
inactivity
Phone 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 card 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 service provider. To 
activate the default group agreed on with the service 
provider, select Default. If you want to use another group 
(you need to know the group index number), select On.
When security features that restrict calls are in use (such 
as call barring, closed user group, and fixed dialing), calls 
may be possible to the official emergency number 
programmed into your device.
Confirm SIM services (network service) — to set the 
phone to display confirmation messages when you use a 
SIM card service
