If you have a PIN number on your SIM card as an extra security measure, you'll need to type the PIN number in each time you turn on your phone. If you do this wrong 3 times, the SIM card will be locked and you will be unable to use the phone. In this situation, you will need your PUK code to unlock the SIM.
WHAT IS A PUK CODE?
These codes have been around quite a long time actually and PUK stands for 'PIN Unlock Key'. It's a unique code that is linked to your specific SIM card and is usually 8 digits long. Some phones may ask for a PUC code instead. This stands for 'PIN Unlock Code' and is exactly the same thing as a PUK Code.
