@Bennyboy your giffgaff sim should work in an O2 locked phone, but try the process here to unlock it first https://community.o2.co.uk/t5/How-to-Guides/Unlocking-an-O2-phone-to-use-a-different-SIM-card/ba-p/1...

@Bennyboy

It sounds as if the phone may have been blocked for some reason. Check here

@Bennyboy ask your friend to put his sim back in the phone and see if it works for him.
