Good to know
Saint Martin shares one island between French and Dutch sides with no border checkpoint — but your phone notices, often switching networks and country codes as you cross. An eSIM keeps a single plan working from Marigot to Philipsburg without surprise roaming.
Unlimited, honestly.

Unlimited plans run at full speed up to a daily fair-use allowance, then at reduced speed until the allowance resets the next day — you're never cut off. Every plan is prepaid: the checkout total is the whole bill, and we never add overage charges.

Hotspot support varies by plan and destination — where it's available for your plan in Saint Martin, it's shown in the plan details before you pay.

The Saint Martin eSIM guide.

Saint Martin packs two nations onto 34 square miles — French bistros in Grand Case, Dutch boardwalks in Philipsburg, and jets skimming the sand at Maho Beach. With rental cars, beach-bar hopping and duty-free shopping filling the days, mobile data steers the maps, splits the bills and shares the plane-spotting clips home.

How it works on the day

Install your eSIM by QR before you fly, then land connected at Princess Juliana (SXM) — the island's only airport. It latches onto Dutch TelCell and Chippie or French Orange Caraïbe automatically, so maps and messages work before you clear the terminal.

Choosing your days

Most visitors stay five to ten days, pairing beach time with a cruise-port stop or an island-hop to Anguilla or Saba. Pick a plan matching your nights and top up if you linger; short cruise-day callers rarely need more than a few gigabytes.

The short version.

A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in Saint Martin, and it finds a partner network on its own.
