eSIM for Saint Martin — Instant 4G/5G Data Plans

Saint Martin's French side is served by operators including Orange Caraïbe and Digicel, while the Dutch side Sint Maarten is served by TelEm Group and UTS. Both sides of the island have 4G LTE coverage across their main populated and tourist areas including Marigot, Grand Case, Philipsburg, and Simpson Bay. The island has no border controls between the French and Dutch sides and coverage transitions smoothly across the open border. Some hillside and remote coastal areas may have slightly weaker signal depending on terrain. Princess Juliana International Airport on the Dutch side and the main beach and marina areas have reliable connectivity. MobiSIM connects through supported local networks to deliver reliable data across Saint Martin's main areas on both sides of the island.

Activate your MobiSIM eSIM before landing at Princess Juliana International Airport on the Dutch side or arriving by ferry from Saint Barthélemy, Anguilla, or Saba so you are connected from arrival. Saint Martin is famous for its beaches, restaurants, and duty-free shopping, and having live data for navigation between the French and Dutch sides and finding beach clubs and dining spots is useful throughout your stay. Keep your home SIM active for calls while MobiSIM handles your data. The island is small and easy to drive around, with live map access making it straightforward to navigate between Orient Bay on the French side and Maho Beach on the Dutch side. If you are taking a day trip to Anguilla by ferry from Marigot or to Saint Barthélemy, note your Saint Martin plan covers the island and you will need separate coverage for neighbouring destinations.
