I sold an iphone 4s to someone in Bolivia. He was not supposed to be able to bid on the item from overseas but he found a way around. In the effort of being nice, I told him I would sell him the phone but could not ensure it would work and that it was unlocked for AT&T. So now, he's got the phone and of course it doesn't work and sim cards are not available there. Can I just send him an inactive Sim? If so, will he be able to get service on the phone with the sim in it? If this won't work will jail breaking it work? Any advice or links for how to's would be greatly appreciated.
