SIM card will be disabled and you need to contact your network 
operator.

You cannot change the PUK code.

PIN2
Some functions on the SIM card can be protected by a 
secondary code feature. Some SIM cards do not have a PIN2 
lock.

The PIN2 lock cannot be deactivated. The code can be changed 
by a user who knows the old code.

The device lock protects your P910a and the data in it against 
unauthorized use. 

If the device lock is set to 

, it means that the 

P910a is not normally locked. However, if the SIM has been 
changed, the P910a asks you to enter the code to unlock the 
P910a before you can use it. This means that if someone steals 
your P910a and puts another SIM card into it, they will not be 
able to use it.

Note Your operator can block your SIM, if you report that your 
phone has been stolen.

The device lock is not on when you buy your P910a. You can 
change the device lock code to any four to eight digit personal 
code.

The default device lock code is 0000.

You can choose to have the P910a locked every time you turn it 
on, locked when the SIM card has been changed, or unlocked.

It is also possible to use the device lock in combination with the 
screen saver. Just mark the checkbox 

 to have the device lock 

activated when the screen saver goes on.

Note When using the screen saving device lock, make sure you 
have set the device lock to activate at Power on. Otherwise your 
P910a will be unprotected after Power on, until the screen saver 
goes on.

Note You will not be able to browse the contents of your P910a 
from a PC, or synchronize items using the SyncStation, when the 
P910a device lock is enabled and active.
