Your eSIMAdventures Martinique plan is exclusively for use within Martinique. Many Caribbean adventurers enjoy island hopping, perhaps taking the L'Express des Îles ferry to explore nearby islands such as St. Lucia, Dominica, or Guadeloupe. Please be aware that once you leave Martinique's territorial waters, your connection will cease. For multi-island expeditions, we recommend securing a regional Caribbean eSIM from eSIMAdventures to ensure continuous coverage across your entire island-hopping itinerary.
