A PUK code is used if you have entered a SIM PIN incorrectly too many times to unlock the sim again

You need to unlock your phone. You can find info on how to do this at https://www.o2.co.uk/help/phones-sims-and-devices/unlocking-an-o2-mobile-to-use-on-a-different-netwo...

You won't be sent a code as it wll be unlocked by Apple after the request has been sent.

As the PAC given only lasts for 30 days, you may need to ask for it again (depending on how quickly you get your phone unlocked)

Good luck and welcome to the forum

Can you be more specific with your issue please?

What message is on your screen when you try and enter the code you have?
