This specific eSIMFlyer plan is provisioned exclusively for use within Saint Lucia. This is an important distinction for travelers planning inter-island excursions. If you decide to take a ferry to Martinique, you'll be entering a different country (which is also part of the EU), and similarly, a ferry to St. Vincent will take you to another independent nation. Your data connection from this Saint Lucia-specific plan will cease once you leave its network coverage. For multi-island itineraries, consider our Caribbean Regional eSIM options for broader coverage.
