Facts & Tips
•If you enter an invalid PIN code three times, your SIM card will be blocked, and to unblock it you have to enter the PUK code supplied by your network operator. This procedure prevents unauthorised persons from working out your PIN code by repeat- edly entering different combinations of numbers.
•For your own sake, remember to write down your SIM lock code to be able to deactivate the lock at a later time. 
You have 10 attempts before the phone is blocked.
•The phone will inform you how many tries you have left before the SIM card is blocked. If you enter an invalid PUK code 10 times, your SIM card will be permanently blocked and you have to contact your network operator.
