What is a PUK for? Is it different from a PAC Code?Ī PUK, which is sometimes known as a network unlocking code (NUC) or personal unlocking code (PUC), is a unique sequence of eight digits that your network must supply, as long as you fulfil certain criteria.Ī PUK is required when you want to unlock a phone. We’ll also 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).

In this guide, we’ll explain exactly what a PUK code is and outline the easiest ways to get one. 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.Īlternatively, 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.

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