I have a couple of Nokia 3310's I found in a drawer, they were mine and my missus's phone, back in the day. I want to get 1 working, just for ha ha's, as I like retro tech. I got a new battery and 1 of them works, but the thing is it's locked to VM, I tried some of the free Nokia unlock codes but they don't work. So I thought the easiest work around would be a VM pay as you go sim, but they don't do them anymore. So I have a couple of questions, will an O2 sim be recognised by the phone as VM (O2 still do PAYG sims), and/or can VM unlock the phone for me?
