Is this NorthESIM plan valid for neighboring islands like St. Lucia or Dominica?

This specific NorthESIM plan is designed for use only within Martinique. While many travelers enjoy island hopping to destinations such as St. Lucia, Dominica, or Guadeloupe via ferries, it is important to note that these are separate sovereign nations. Your Martinique data plan will not provide coverage there. For continued connectivity across multiple Caribbean islands, consider purchasing individual NorthESIM plans for each destination or exploring our regional Caribbean options.
