Is this CoreESIM valid for inter-island ferry travel to <strong>Martinique</strong> or <strong>Guadeloupe</strong>?

This CoreESIM offering is strictly geo-restricted to the sovereign territory of Dominica. For travelers engaging in inter-island transit, particularly via ferry to neighboring French overseas departments like Martinique or Guadeloupe, it is critical to understand that cellular service will cease upon entering French territorial waters. These islands operate under the European Union's telecommunications framework, which is distinct from Dominica's independent network. A separate regional or country-specific eSIM would be required for continued connectivity.
