Just trying to figure out our best phone option for our move next month. We'll be traveling through Mexico for at least 3 weeks, then into Belize for an extended period of time (hopefully, permanently). T-Mobile tells us we can use their service in Belize at no additional cost, but I'm not convinced. Anyone using T-Mobile? We're just trying to find the cheapest, easiest option. Skype? Vonage? Magic Jack? BTL?
