Is this eSIMAdventures plan valid for ferries to Dominica, Martinique, or Saint Lucia?

This is a crucial point for Caribbean island-hoppers! Your eSIMAdventures plan is valid for Guadeloupe and Martinique, as both are French overseas departments and part of the EU, offering seamless connectivity between them. However, it will not extend to independent nations like Dominica or Saint Lucia. Once your ferry crosses into their territorial waters, your connection will cease. For multi-country Caribbean adventures, we recommend exploring our regional plans that cover a broader spectrum of islands.
