No, free roaming with your EU, UK, or US mobile plan is not available in Sint Maarten. Despite its connection to the Netherlands, Sint Maarten is outside the European Union's 'Roam Like At Home' zone. This means if your group relies on your domestic SIM, you'll face substantial international roaming charges for data, calls, and texts. To avoid unexpected high costs for everyone, Triply offers a simple and cost-effective eSIM solution, ensuring your whole crew stays connected affordably across the island.
