Brian's son has a phone with Verizon that can't be used overseas. He could purchase a world phone from Verizon because they do make them. He also could get an unlocked GSM phone, and then when he goes to France, get a SIM card there. That would give him a French number, and would be a lot cheaper than paying for an international plan. It also would most likely include texting and data. Some countries make it easier to do this than others, though. It may be a better idea to just buy a cheap phone when he gets there.
