This particular WorldESIM plan is exclusively for use within Saint Lucia. For travelers planning to take ferries to neighboring islands like Martinique (which is part of France/EU) or St. Vincent, it's important to note that your data connection will cease as you enter a new country's territory. WorldESIM specializes in global connectivity; for multi-island explorations in the Caribbean, we recommend our comprehensive regional eSIM bundles, designed to provide continuous data across various nations, simplifying your island-hopping adventures.
