I use Nobelcom for me, in the USA to call to JA. From other posts, look like others might be cheaper, maybe have to explore.
Most times I talk for just a few minutes and have my fiancee call me back on the Digicel Int'l minutes I have sent her.
Or do I misunderstand you - and there is an International Plan here in the USA to call JA you are referring to?
if you are using nobel you might want to check out enjoyprepaid- it's nobel without the annoying PIN and stuff.
between the digicel and skype, I saved a ton of money, gave up on the cards soon after skype and that is also video. also oovoo is popular.
