Lock if SIM card changed: - You can set the smartphone to ask for the lock code when an unknown, new SIM card is inserted into your smartphone. The smartphone maintains a list of SIM cards that are recognised as the owner’s cards.

PIN codes

PIN code request: - When active, the code is requested each time the smartphone is switched on. Deactivating the PIN code request may not be allowed by some SIM cards. If you enter the PIN code incorrectly three times in succession, you will need a PUK (PIN Unblocking Key)

code to unblock the SIM card. When the SIM card is blocked, you can only make calls to preprogrammed emergency numbers. Otherwise, you cannot use the smartphone before you enter the appropriate codes.

Note that this setting cannot be changed, if the phone is switched off or if there is no valid SIM card inserted. Note also that some SIM cards do not allow you to turn the PIN code request off.

Confirm SIM services: (network service) - To set the smartphone to display confirmation messages when you are using a SIM card service.

PIN code: - The PIN code must be from 4 to 8 digits long.

PIN2 code: -The PIN2 code must be from 4 to 8 digits long. The PIN2 code is required to access some functions, such as the call cost settings, which must be supported by your SIM card. If you enter an incorrect PIN2 code three times in succession, you will need a PUK2 code to unblock the PIN2 code. The new PIN2 code must be from 4 to 8 digits long.

Call barring

Barring password: - Tap Change to change the barring password. The barring password must be four digits long. If you enter an incorrect password three times in succession, the password is blocked and you must ask the network service provider for a new password.
