You could sign up temporarily for CCT Flexphone prepaid service, but the sim card wouldn't likely be good outside the BVI (maybe you could resell it on ebay for someone else visiting there). Use a local prepaid long distance card or callback service if their international rates are too pricey for your budget.

Another solution might be VOIP like Skype or Vonage if the BVI property you're staying at has complimentary wi-fi. Experimented with Skype from Nevis earlier this month; worked but person I called in the USA said voice quality was somewhat tinny and had some echoes. Might have been just the wi-fi connection I was using or my wi-fi device. Used a United Mobile GSM sim card in preference to Skype because voice quality was better(but United Mobile obviously won't work in the BVI).

Have visited the USVI several times and have heard that BVI signals can sometimes be picked up and vice versa due to the proximity of Tortola(stories of people getting sticker shock at unintentional postpaid roaming). While legally not supposed to happen you might be able to take advantage of this quirk to pick up a US carrier with your domestic USA prepaid sim card in either a high location and/or shoreline location(a prepaid USA sim would either work on the USVI system or not all).
