Our verdict on SIM cards in US Virgin Islands
Best for: US domestic travelers, St. Thomas cruise visitors, St. John hikers, Caribbean yacht sailors (US territory harbors).
The USVI and Puerto Rico are the only Caribbean destinations with genuine US domestic carrier coverage. Every other island requires a separate SIM. The adjacent British Virgin Islands (Tortola, Virgin Gorda) use entirely different carriers and require a separate plan.
