My vodafone phone has died, and I'm nowhere near the end of my contract to be entitled to an upgrade. So I figure I'll get a cheap pay as you go phone to put the sim into. It seems a bit pointless to get a vodafone pay as you go with credit that I'll never need, so I was thinking I'd get an orange one (I can use the credit on Orange wednesday film texts). Is it possible to get an already unlocked orange pay as you go phone that will let me use my vodafone sim too?
