unlocking an old iPhone to use with payg

[HarryBosch]

I want to unlock an old 02 iPhone 6 to give to my grand daughter with a payg shop bought o2 sim and I can't find a straight forward way to do this. All I can find is how to swap my current sim. Any help would be greatly appricated

Here is some PAYG info that might help, @HarryBosch 

Guide: Unlocking an O2 phone to use a different SIM card and Guide How to Top Up (PAYG) and Guide: What code do I need: PAC or PUK.

Good luck!

If it is an o2 iPhone then the o2 PAYG sim should just work.

Remember that the new PAYG is more like a monthly bundle...
