This specific Triply eSIM plan is designed to keep your group connected exclusively within Martinique. It's common for travelers to hop on the L'Express des Îles ferry to visit nearby gems like St. Lucia, Dominica, or Guadeloupe. However, be aware that St. Lucia and Dominica are independent nations, and your Martinique eSIM won't work there. If your crew plans island-hopping, we recommend securing individual regional eSIMs from Triply for each destination to ensure continuous connectivity.
