Frequently Asked Questions - St. Martin eSIM
Yes - eSIMs work fully in St. Martin on local carrier networks. Activation is simple: buy a plan, get a QR code by email, scan it in Settings → Cellular → Add eSIM, and turn on mobile data. The whole thing takes 2–3 minutes.
Our eSIMs run on local 4G/5G networks in St. Martin. Urban speeds average 30–100 Mbps - plenty for video calls, streaming, and social media. Rural coverage can be slower, but 3G is widely available as a fallback.
eSIM is supported by iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3 and newer, Huawei P40 Pro+, and most other modern smartphones. Run your phone through our compatibility checker before buying.
Most eSIM plans are data-only. For calls and messages, use WhatsApp, Viber, Telegram, or similar apps over Wi-Fi or mobile data. A handful of plans include a local phone number - that's clearly flagged on the plan details.
Just buy a new plan straight from our website or app - your new QR code arrives within seconds. Unlimited plans never run out.
Most modern phones hold 8–10 eSIM profiles, but only one can be active at a time. Delete old eSIMs and add new ones whenever you need to.
Local plans cover one country and are usually the cheapest option. Regional plans cover a group of countries (e.g., across Europe) and are ideal for multi-country trips. Global plans work in 173 countries - more expensive, but you pay once for worldwide coverage.
Yes - eSIMs are completely safe. They're embedded in your phone, so they can't be physically stolen or lost, and data is encrypted just like on a regular SIM card.

Why Travelers Choose an eSIM for Saint Martin
Flying into Grand Case (SFG) for the French side of the shared island, Marigot town, Grand Case gastronomy, or Orient Bay beach? A Saint Martin eSIM connects to Digicel or Orange Caraïbes on arrival. As a French overseas collectivity, EU Roam Like At Home may apply. Activate in two minutes for Marigot ride coordination, restaurant reservations, or Dutch-side (Sint Maarten) crossing. Choose 7-day for an island week, or Caribbean regional eSIM for multi-island trips.
