Understanding the Two Sides: French Saint-Martin vs Dutch Sint Maarten
Before we dive into connectivity options, it's crucial to understand that this Caribbean island is divided between two nations. The northern 53 km² is French Saint-Martin (🇫🇷), an overseas collectivity of France with Marigot as its capital. The southern 34 km² is Dutch Sint Maarten (🇳🇱), a constituent country of the Kingdom of the Netherlands with Philipsburg as its capital. While you can freely cross between both sides without passport control, they maintain separate governments, currencies, and importantly for travelers—separate mobile networks.
Good news: eSIMfly offers plans for both coverage scenarios! Choose Regular Data plans if staying on the French side only, or select Regional/Global packages if you want to explore the entire island including the famous Dutch side attractions like Maho Beach, Philipsburg duty-free shopping, and Simpson Bay casinos.

Why Choose eSIM for Saint-Martin/Sint Maarten
Landing at Grand Case Airport (SFM) on the French side, or Princess Juliana Airport (SXM) on the Dutch side, you'll immediately appreciate the convenience of having an eSIM already activated. Unlike purchasing local SIM cards—which requires visiting French carrier shops in Marigot or Dutch shops in Philipsburg, often with language barriers and limited hours—an eSIM from eSIMfly can be purchased and activated before you even leave home.
Both sides maintain excellent mobile infrastructure. The French side offers European-quality networks (Orange Caribbean, SFR Caraïbe), while the Dutch side has robust 4G coverage through TelCell and Flow. With a Regional/Global eSIM package, you'll seamlessly connect to networks on both sides, giving you immediate access to maps, translation apps, ride-hailing services, and restaurant reservations without any delays or paperwork.
The flexibility of choosing your coverage type means you only pay for what you need. Staying in Grand Case for a week? Regular plans offer the best value. Exploring the entire island from Maho Beach to Orient Bay? Regional/Global packages ensure uninterrupted coverage across all 87 km² of this dual-nation paradise.
Mobile Network Coverage Across the Island
French Side Networks (All Plan Types)
The mobile network landscape in French Saint-Martin is dominated by three main operators, all providing excellent coverage across the French territory. Orange Caribbean (formerly Orange Caraïbe) is the primary network, part of the Orange France family, offering the same European-quality service you'd expect in mainland France with 98% coverage. SFR Caraïbe provides competitive 95% coverage with good speeds. TelCell N.V. offers an alternative network with 92% coverage in major areas. All three operators provide robust 4G LTE coverage across the populated and tourist areas of the French side.
Whether you choose Regular plans or Regional/Global packages, you'll have full access to these French networks. Your device automatically connects to the strongest available signal from Orange, SFR, or TelCell as you explore from the bustling Marigot market to the serene beaches of Anse Marcel.
Dutch Side Networks (Regional/Global Plans Only)
On the Dutch side of Sint Maarten, TelCell and Flow/UTS provide excellent coverage across the 34 km² Dutch territory.

Best Uses for eSIM in Saint-Martin/Sint Maarten
An eSIM transforms your smartphone into the perfect Caribbean travel companion for this unique dual-nation island. Navigation is essential—Google Maps helps you find Grand Case's hidden gourmet restaurants on the French side, navigate to the famous Maho Beach plane-landing spot on the Dutch side, discover both Philipsburg and Marigot shopping districts, and locate Pinel Island ferry departures. Translation apps are invaluable for reading French menus in Grand Case and understanding Dutch signage in Philipsburg.
Communication apps like WhatsApp and FaceTime let you make free calls home while sharing your Orient Bay beach photos on Instagram in real-time, or uploading those incredible Maho Beach plane-landing videos. For foodies, having data means you can research restaurant reviews on both sides, make reservations at top Grand Case French establishments or Philipsburg waterfront restaurants, and share your culinary adventures instantly from either territory.
Important for Plan Selection: If you plan to visit Maho Beach (Dutch side), Philipsburg shopping, or Simpson Bay marina, you MUST choose Regional or Global packages. Regular plans do NOT cover the Dutch side and you'll lose connectivity when crossing the border.
