Can I use one eSIM on both the French and Dutch sides of Saint Martin?

Yes. Our Saint Martin eSIMs connect to local networks that provide coverage across the entire island, both the French (Saint-Martin) and Dutch (Sint Maarten) sides. You don’t need separate plans or to worry about roaming when crossing the internal border. Once installed and activated, your eSIM will automatically connect to the best available partner network, so you can use maps, ride-hailing apps, and messaging seamlessly as you move between Grand Case, Orient Bay, Simpson Bay, Maho, and beyond.
