The NorthESIM plan for St. Barths is strictly for use within St. Barths itself. It is not valid for Sint Maarten (SXM), which is a separate territory where most international flights land. As you transition from Sint Maarten to St. Barths, your connection will activate upon reaching St. Barths. For continuous connectivity from your arrival at Sint Maarten, we advise considering a regional NorthESIM plan that encompasses both islands.
