Fortunately, the process is straightforward, quick, and simple; we're going through all the methods you need to know.

How to get your PUK code

A PUK code is a Personal Unlocking Key, an eight-digit number, that's needed to unlock a SIM. You can find it from the original packaging that your mobile phone came with; it's usually printed on the back of the SIM card package, or found printed on the tray.

What if you've lost your SIM card packaging, or if you only had an eSIM in the first place, then? The easiest way to get a PUK code is to call Talkmobile on 0333 304 8064 from another mobile device, in which case you can request the Personal Unlocking Key. It's important not to guess this eight-digit figure, however, because your SIM could be permanently blocked after 10 wrong attempts.

It's also vital that you know that a PUK code is not a PAC/STAC code. The Personal Unlocking Key is wholly unique to the SIM/eSIM as part of the Subscriber Identification Module, some of the essential info stored on a SIM card.

Step by step guide to get a PUK code

  • Check the plastic card that arrived with your original SIM when purchased
  • Alternatively call Talkmobile on 0333 304 8064
  • Enter the eight-digit PUK code when prompted
  • Set a new PIN for your SIM, which will be needed to access it in the future
