I have had an older Motorola flip phone unlocked with a CCT 'SIM' for years. I think I might have gone to their office to obtain the SIM card, and now I can reload online with a few bucks before each trip. It works fine for local calls, although I've never tried it for long distance or data. I have noticed the AT&T signal from St. Thomas seems to be stronger when in BVI this past December. Once I obtain the AT&T signal, I've got the 'works' under my plan at home in the States.
