Hello there,

The PUK code is the PIN UNLOCK KEY. You get this when the PIN is entered wrong for 3 times consecutively. What you can do about this is to call your phone / network provider. I am pertaining to the SIM card provider. Just tell them you need the PUK code, they should be asking some info like account name etc. But other than that, they should be able to unlock it.

Good luck!

PUK stands for 'Pin Unlock Code', and has to be entered if you've locked your SIM by repeatedly entering the wrong PIN code. If you're asked for a PUK code, you've had more goes at guessing your SIM card PIN code than you're allowed. You'll need to phone your network provider Customer Services for your PUK code to unlock the SIM. For security reasons, it's only the network operator that can legally provide you with a PUK code to unlock your SIM.With some phones you will get a cert card with your sim card and it might have the 8 digit PUK on it. if this has been entered 10 times or more incorrectly then you will need a new sim card
