those minutes/credits are good to call the USA too -- there's probably just not enough credit in the loaner phone to do it - but regular ol' Digicel credit/minutes are good to call anywhere, local or international.loaner phone from our usual driver ............. he fills it with minutes for Jamaica calls only ............
The unlimited monthly international plan isn't *necessary* to be able to call internationally-- it's just more economical if you plan to talk a LOT, or stay on-island for long term. (and it only works for international - it cannot call locally). Regular phonecards/credits work just as well; when i'm there just for a week i usually get a 500 J phone card - about half the cost of the monthly plan.
Yah - that's the monthly international plan ppl are speaking of -- your driver probably has that on his personal phone. And since it's good for unlimited calls, it's cheaper for him to just let you use that to call home - as opposed to buying additional 'regular' phonecards/credit to add to the phone he lends you............ somehow they know how to call USA for darn near NOTHING ! ! !
