I have Tmobile, and although the coverage here is not superb, I have been amazed by the free coverage outside the US at no cost. Texting and 3g (sometimes 4g) internet service is free. Calls are reasonable, my memory is 20 center per minute. I used to pay through the nose for Verizon coverage outside the US and it is wonderful to have free coverage practically everywhere, like 180 countries or something.
