CaribbeanMarigotSaint Martin eSIM and Travel Guide: Stay Connected on the French Side
Saint Martin is a unique divided island where French-side phones connect to Orange, SFR and Dauphin Telecom, and the island shares infrastructure with Dutch Sint Maarten. A Roamix eSIM connects to Orange Caribbean or SFR on the French side with good 4G and emerging 5G coverage in Marigot and Grand Case. Connectivity is excellent on both sides of this borderless island. Download offline beach maps before exploring the more remote bays.
Key Takeaways
- Orange Caribbean is the primary French-side operator with up to 5G coverage in Marigot and main tourist areas.

- A Roamix eSIM activates on arrival at Princess Juliana or Grand Case Airport and covers the full island through French-side networks.
- The Euro is the currency on the French side; the US dollar dominates on the Dutch side and is accepted everywhere.

Get your Saint Martin eSIMMobile Networks in Saint Martin
Saint Martin's French side is served by Orange Caribbean, SFR Caraibe and local operator Dauphin Telecom, all running 4G and in Orange's case early 5G in the main towns. The island has no border controls with Dutch Sint Maarten, so your French-side eSIM can roam to Telcell and TelEm on the Dutch side, giving effective full-island coverage. A Roamix eSIM connects to Orange Caribbean or SFR on arrival at either airport.
Dominant French-side operator with 4G LTE and emerging 5G across Marigot, Grand Case, Orient Bay and Cul de Sac. Also extends coverage into Dutch Sint Maarten through inter-operator agreements. 98 percent French-territory coverage.
Second French operator with solid 4G LTE across the main tourist areas. 95 percent coverage of the French side. Roams on TelCell for Dutch-side coverage when needed.
Local operator based in Marigot with a 4G network covering both the French side and Saint Barthelemy. Offers free roaming on the Dutch side via TelCell and competitive prepaid plans.
Typical Speeds
Orange 4G Plus delivers 20 to 60 Mbps in Marigot and Grand Case. Orange 5G reaches up to 150 Mbps at peak in strong coverage zones.
5G Status
Orange Caribbean has deployed 5G in Marigot, Orient Bay and the main French-side tourist corridors.
If your French-side phone roams to a Dutch-side operator in Sint Maarten, you may be on TelCell or TelEm rather than Orange. This is normal and gives you full-island connectivity for activities like Maho Beach plane spotting and Philipsburg visits.
Some of the more isolated beaches in the northeast and the ridge roads between the two sides of the island can have lower signal from all operators. The tiny offshore island of Tintamarre (Flat Island) is off-grid.
Orange Caribbean uses standard European LTE and 5G bands compatible with all recent unlocked smartphones. EU-spec and US-spec iPhones from XS onward all work correctly.
Data Usage Guide
Data needs on Saint Martin are moderate. The island is small and most attractions are close to strong Orange 4G or 5G coverage, but beach navigation and offline maps are useful for the more remote bays.
Download offline maps for the entire island including access tracks to Friar's Bay, Happy Bay and the nature reserve beaches before heading out.

Get connected the moment you land in Saint Martin.
Get your Saint Martin eSIMArrival Checklist
Confirm your Roamix eSIM has connected to Orange or SFR before leaving the arrivals hall at Princess Juliana (SXM) or Grand Case (SFG).
Note that Princess Juliana Airport is on the Dutch side, so you may initially roam to a Dutch-side operator before switching to Orange or SFR as you cross to the French side.
Download offline maps for both sides of the island, including the beach access roads and the scenic ridge road between Marigot and Philipsburg.
Confirm whether your accommodation takes Euros or US dollars, as both are widely used on the island.
Check whether you need a French side entry card or customs form, particularly if arriving from outside the EU or Schengen area.
How locals communicate
WhatsApp is universal on Saint Martin for both sides of the island. French-side businesses often use SMS and French messaging norms, while Dutch-side contacts skew toward WhatsApp and iMessage.
Keep your home SIM active for SMS two-factor authentication while using the Roamix line for data. Note that calling from a French-side number to a Dutch-side number is technically an international call (+1-721).
Airports in Saint Martin
Princess Juliana International Airport
Simpson Bay, Dutch Sint Maarten
Free Wi-Fi available at Princess Juliana Airport. Note this is on the Dutch side of the island, so your French-side eSIM may initially connect to a Dutch-side operator before switching to Orange or SFR.
Even though SXM is on the Dutch side, your Roamix eSIM roams to Dutch-side networks seamlessly. Drive across the invisible border to Marigot and it switches to Orange Caribbean automatically. Great for Maho Beach plane spotting on arrival.
Grand Case - Esperance Airport
Grand Case, French Saint-Martin
Small terminal with limited Wi-Fi. Serves regional routes to Guadeloupe, Martinique and Saint Barthelemy. Orange 4G is strong at this French-side airport.

Saint Barthelemy Gustaf III Airport
Gustavia, Saint Barthelemy
If day-tripping to Saint Barths from Saint Martin, this tiny airstrip uses the same French-side telecom infrastructure. Signal can be intermittent on the approach.
For the short hop to Saint Barths on Winair or Saint Barth Commuter, download accommodation and beach maps over Roamix data at SFG before boarding.
Guadeloupe Pole Caraibes Airport
Pointe-a-Pitre, Guadeloupe
If connecting through Guadeloupe on the way to Saint Martin, free Wi-Fi is available at the modern Pole Caraibes terminal.
On multi-island Caribbean itineraries, ensure your Roamix eSIM is active before landing at any connecting airport to manage transfers and navigate to connecting gates.

Frequently Asked Questions
Saint Martin eSIM, connectivity, and travel
What is the best eSIM for Saint Martin?
Roamix is an excellent choice for Saint Martin, connecting to Orange Caribbean which provides 4G and 5G coverage across the French side with seamless roaming to Dutch-side networks. You install it before departure and land at Princess Juliana already connected.
Do I need a SIM card for Saint Martin?
You do not need a physical SIM. A Roamix eSIM activates on Orange Caribbean or SFR on arrival at either airport on the island, covering both the French and Dutch sides as you explore. SIM cards from Orange are only available in Marigot town, not at the airports.

Orange Caribbean has deployed 5G in Marigot, Orient Bay and the main French-side tourist areas, reaching up to 150 Mbps at peak. SFR and Dauphin Telecom are still 4G LTE.
Can I use my EU SIM card in Saint Martin?
Yes. Saint-Martin is a French overseas collectivity and part of the EU's outermost regions, so EU SIMs benefit from Roam Like At Home rates on the French side. Note that crossing to Dutch Sint Maarten is technically leaving the EU's Roam Like At Home zone.

Yes. Saint Martin has a fully open internet. WhatsApp, FaceTime, social media and streaming all work on both sides of the island without any VPN.
What is the Heineken Regatta?
The Heineken Regatta in late February to early March is one of the world's most famous sailing events, drawing hundreds of yachts from around the world to race in the waters around Saint Martin over four days of competition and beach parties.
Is it worth visiting the Dutch side from the French side?
Absolutely. There are no border formalities. Dutch Sint Maarten offers the Maho Beach plane spotting experience, Philipsburg duty-free shopping, the casino strip and a different cultural vibe. Your Roamix eSIM roams seamlessly to Dutch-side networks throughout.
