Will my <strong>eSIMFlyer</strong> for <strong>Guadeloupe/Martinique</strong> remain active if I take a ferry to <strong>Dominica</strong>, <strong>Martinique</strong>, or <strong>Saint Lucia</strong>?

This is a crucial point for Caribbean island-hoppers. Your eSIMFlyer plan for Guadeloupe and Martinique is valid across both islands, as they are French overseas departments and part of the EU roaming zone. However, it will not provide coverage in Dominica or Saint Lucia. These are independent, non-EU nations with separate network infrastructures. Your connection will terminate as you exit the French territorial waters. For seamless multi-island journeys, consider a regional Caribbean eSIMFlyer or separate country-specific plans.
