yeah use an unlocked quad phone in Jamaica.....you can buy dem in N America and bring dem down
buy GSM phones that use like AT&T or T-mobile etc and you can unlock them yourselves by getting the codes on Ebay.......
quad means they can use either Digicel or FLo network.......or buy a phone in Jamaica as they are cheap enuff.......
Digicel is the carrier to use....though nothing wrong with Flo except der signal weak in some areas..
Digicel had a special this Summer and you could get a Sim for a likkle over $300J's....normally they are almost $600J's
the Flo sim cards are only $300J........but locals hate chatting with you since you can burn up all der Digicel credits..

most locals and tourist put credit on der phone and then select the plan dem want so der data on the phone for FB, Whatsapp, etc
you have 2 different 7 day plans currently on Digicel....$650J for 1GB or $350J for a 500GB...mi find the 500GB is plenty for mi..
a lot of locals like the 2 day plans.......dem like $130J's for quite a bit of data.........so most choose dat......
of course you can add International calling too...but seriously if you are only going to make some brief internationals calls....
you don't need the international plan.......international are for those that have to chat a lot........a real lot....ha ha

dat mi 2 cents.......or mi 2J dollars worth......lol
