I'll be traveling to Grand Cayman next January, and might be switching cell phones between now and then. I was just wondering which is the best for travelling the Caribbean, and elsewhere. What kind of experiences has everyone had? My only international trip was to Puerto Aventuras, Mexico. I got very spotty service; was only able to make about 1 call in 6, with my AT&T/Nokia 8260.
