About PUK code

A PUK code (Pin Unlock Key) is required when you enter an incorrect PIN (Personal Identification Number) 3 times. After entering the wrong PIN 3 times, the card will be locked and you will need to get a PUK code from your service provider to unlock it.

Once your PUK has been send to you, you should enter it into your phone to set a new PIN code, that will be four zeros "0000"

Note: If the wrong PUK code is entered ten times, the SIM card becomes invalid and you will need to get a new SIM Card. The phone will display "PUK blocked call operator". that will cost you money.

So please be carefull before entering PIN and check twice.
