We bought a phone from batelco with wifi
capabilities and used it in the bahamas. You just need an unlocked phone with internet capabilities. It was $30 a month for internet service if you were around a cell tower. It worked, but it was pretty slow. Gettting email
and surfing sites was slow, uploading pictures was almost impossible. Still, it was great for getting what we needed, emails, weather
I had a cell phone
booster we plugged into the cigarette lighter which I think helped a lot. If we didn't have it, I think it would have been even slower.
