PUK Code - UK Help and Advice

Information and advice relating to PUK codes, and how to handle a locked SIM card in the UK

Unlock Mobile Phones

 

What is a PUK?

PUK stands for Personal Unblocking Key, and it's a code that's associated with a mobile phone SIM card.

 

Why am I being asked for a PUK?

Your mobile phone's SIM card has a four-digit PIN code enabled by default. If you enter the PIN code incorrectly three times, a lock will be put onto the SIM card, and you need a PUK code to unlock it. If your mobile phone is asking you for a PUK, then one of two things has happened:

  • You have entered the SIM card's PIN code wrongly three times.
  • Your network operator has locked your SIM card (this normally happens when the SIM is reported lost or stolen).

 

Where do I get a PUK?

If you're being asked to enter a PUK, you will need to contact your network operator to get your SIM card unlocked. This is for security reasons. Note that only your mobile phone network operator can legally provide you with a PUK code to unlock your SIM card.

Q. What happens if I enter the PUK code incorrectly?
