Your WorldESIM plan for Martinique is designed for exclusive use within the island's geographical boundaries. If your Caribbean itinerary includes island hopping to destinations such as St. Lucia, Dominica, or Guadeloupe via the L'Express des Îles ferry, your Martinique eSIM will not provide connectivity in those independent nations. For seamless multi-island travel, WorldESIM recommends exploring our Caribbean Regional eSIM options or dedicated plans for each country, ensuring you remain connected from Castries to Roseau.
