We have T-Mobile which includes a WiFi calling feature, anywhere we find WiFi we have unlimited calling back to the US. Our charter includes a phone for use in the BVI if needed. We choose to disconnect from the web when coming down, with the occasional "check ins" on FB to rub it in a little to all our friends back home. We've found it to be the best way to leave the world behind and enjoy being in the moment. Our BVI time is limited (once every two years or so) and disconnecting for those 9 days is part of it. Just my $.02...
