Your SouthESIM plan for Martinique is specifically designed for use within its beautiful borders. While island hopping to nearby gems like St. Lucia, Dominica, or Guadeloupe is a popular adventure, please note that your connection will only work in Martinique. If your Caribbean journey includes multiple islands, consider grabbing a separate SouthESIM for each destination or checking out our regional Caribbean bundles. It's the most budget-friendly way to stay connected across the vibrant Lesser Antilles!
