I use T-mobile in Jamaica. They charge only 20 cents a minute and unlimited text in Jamaica. Use my own phone and never have to do the digicell shuffle. If you have Jamaican friends they are all using WhatSapp which is free. Sounds like not many use t-mobile, but I ended up spending $6 on calls my last trip. To call another country I just use wifi connection at the hotel so those calls are free.
