Best eSIM for Montserrat

Montserrat is a Caribbean island reshaped by its volcano. The Soufrière Hills eruptions buried Plymouth and closed the southern half of the island as an exclusion zone, and life moved north to Brades and Little Bay, where the government offices, the ferry berth and most visitor accommodation now sit. Arrivals come by air into John A. Osborne Airport (MNI) or by ferry from Antigua, usually for the volcano observatory, the diving, or family connections to this British Overseas Territory. With so few visitors and a small island to cover, a travel eSIM bought before you go is far simpler than looking for a SIM on arrival, and its validity starts only at the first connection here.

Digicel and Flow are the networks serving Montserrat, and coverage concentrates on the inhabited north: Brades, Salem, Little Bay, Woodlands and the airport at Gerald's. The steep ridges mean signal comes and goes on the winding roads between them, and the southern exclusion zone is not somewhere you should be relying on a phone in any case. Offline maps cover the island easily given its size.

For a short stay on an island this small, a local SIM is more trouble than it is worth. An eSIM installed before you board the ferry from Antigua has you connected the moment you land, with your home number still live. Note that an Antigua plan does not extend here, so if you are island-hopping, buy for each. Roaming is the costly fallback.
