What is PUK code?
The PUK (Personal Unblocking Key) code is a code consisting of 8 digits. It is used to unblock your SIM card when you entered 3 times a wrong PIN code. A card blocked by the PUK code cannot be unblocked; it cannot be used any further and you have to replace it.

Personal unlocking keys (PUKs) are required by some networks when you want to unlock your phone.

You may want to unlock your phone because you want to use it with another SIM card, or because you’ve opted to switch network.

Alternatively, it may be that you’ve accidentally entered the wrong PIN too many times and now need a PUK to unlock your SIM card and start using it again.

In this guide, we’ll explain what a PUK code is and outline the easiest ways to get one. And we’ll look at which networks require PUKs to unlock phones, as well as clear up the difference between a PUK and a PAC (porting authorisation code).
