We used to use Lime for our cell service on the boat. I now use my T-Mobile account, no international data cost and setup my phone to be a hot spot. Speed isn't blazing and you can't stream but that isn't an issue for us.

You have to force the phone not to try to connect to tmobile and stay on digicell when in range of St Thomas as the data coverage in STT is horrible, coverage in BVI is great, even on Anegada.

ATT will cost you a fortune even with a international plan.
