The WorldESIM plan specifically for St. Barths provides coverage exclusively within its borders. Given that most international flights arrive at Sint Maarten (SXM) before onward travel to St. Barths, it's important to note that this particular eSIM will not be active in Sint Maarten. For travelers navigating multi-island itineraries, WorldESIM offers flexible global or regional eSIMs that include both Sint Maarten and St. Barths, ensuring continuous connectivity from the moment you land.
