Compare eSIM plans for the British Virgin Islands

More visitors here sleep on a boat than in a hotel, and the network has been built around that. Capacity sits where the charter fleet stops : Road Town and the marinas, Soper's Hole, Great Harbour on Jost Van Dyke, Spanish Town and North Sound on Virgin Gorda. Those are the places where a few hundred extra devices arrive at anchor each evening, and where a signal is genuinely reliable. Under way between islands it is line of sight to whichever hill is nearest, which in a compact archipelago is usually enough, but never something to plan a passage around.

• ●Tortola carries the bulk of it, from Road Town and Beef Island airport along the ridge road to Cane Garden Bay. Virgin Gorda is the second strong island, covering Spanish Town, The Baths and the North Sound mooring fields. Peak charter season, roughly December to April, puts real load on those same harbours in the evening.
• ●Jost Van Dyke works around Great Harbour and White Bay with dead spots in the sheltered coves. Anegada, flat coral fifteen miles north of the rest, has thin coverage that fades quickly away from The Settlement. Norman Island and the uninhabited anchorages rely entirely on what the nearest inhabited island throws across the water.
• ●One practical warning for a chartered week : the US Virgin Islands are a separate country with a separate plan, and from high ground on Tortola their network is often the strongest thing your phone can see. Set network selection to manual at the start of the trip and choose a local carrier.
