Prices in USD, checked Nov 9, 2026. Rows marked "Not yet verified" haven't been checked on the provider's own site yet; we work through them each month. How we compare
Not sure you need one? Do I need an eSIM? compares it with roaming, a local SIM and Wi-Fi. Staying a week or more? Our vacation eSIM guide covers plan length and how much data you need.
Keeping your own phone plan? Using your phone in St. Maarten covers AT&T, Verizon and T-Mobile, the local networks and what changes on the French side.
On a cruise stop in St. Maarten
Ships dock at Philipsburg on the Dutch side. If your excursion crosses to the French side (Marigot, Orient Bay, Grand Case), your eSIM may switch to another network or lose data there unless the plan covers both sides.
Keep cellular data off while the ship is at sea and switch the eSIM on once you’re ashore. Our Caribbean cruise eSIM guide explains why, and how to cover several islands with one plan. For data at sea, our ship Wi-Fi guides compare each line’s packages with a cruise eSIM: Royal Caribbean, Carnival, Norwegian, MSC and Princess.
Which network will I be on?
Airalo (its plan is called Lantana) says it uses TelCell, one of Sint Maarten’s local networks. Other providers in the table don’t always say which network they use; those rows show “Not stated”.
Dutch side and French side
The island has two halves with two sets of networks. Sint Maarten, the Dutch side, has Philipsburg, the cruise port and Princess Juliana Airport. Saint-Martin, the French side, has its own networks. Most eSIMs in this table are sold for Sint Maarten only.
If you’ll spend most of your time near Philipsburg or Maho Beach, a Sint Maarten plan is enough. If you’re staying on the French side, or driving round the island, pick a plan that covers both. The Caribbean plans from Roamless, Ubigi and Yesim list Sint Maarten and Saint-Martin. Airalo’s and Kolet’s plans are for the Dutch part only, and so is Yesim’s Netherlands Antilles plan.
Common questions
Does an eSIM work in St. Maarten?
Yes. Travel eSIMs from Airalo, Nomad, Holafly and others connect to local networks in St. Maarten, such as TelCell. Your phone must support eSIM and be unlocked.
What’s the cheapest eSIM for St. Maarten?
The cheapest verified short plan is Airalo’s 1 GB for 3 days at $8 (checked ). The table above is sorted by price, so the first rows are the cheapest for each trip length.
Does a St. Maarten eSIM work on the French side?
Not always. Sint Maarten (Dutch) and Saint-Martin (French) have separate networks, and many eSIMs cover only one side. If you’ll visit Marigot or Orient Bay, check that the plan lists both. The Caribbean plans from Roamless, Ubigi and Yesim do.
Will my eSIM work when I land at Princess Juliana Airport?
Princess Juliana Airport is on the Dutch side, so a Sint Maarten plan can connect as soon as you land. Install the eSIM at home first, because you need Wi-Fi or data to download it.
