Unlocking a new sim

[Alf2]

Help! I purchased a monthly sim account from the O2 shop in Exeter on the 20/05/24. I have put the Sim card in my phone and it asks for SIM network PUK. what is that?

How can I unlock the SIM card.

This guide should help you Guide: What code do I need: PAC or PUK

Not sure why any O2 shop should give you a new sim requiring a PUK?

Take the phone and sim with ID back to the shop and ask  them to sort it for you.

Sounds like your phone is locked to a previous network.

Go back to whichever network you last used your phone on and ask them to unlock it.
