This specific plan is valid only within Dominica. This is the most critical point for "island hoppers." Martinique and Guadeloupe are part of France (and the EU), while Dominica is not. Your connection will stop the moment your ferry enters French waters. For a multi-island trip, we highly recommend our Caribbean Regional eSIM.
