Best eSIM for St Maarten Travel

 Why use an eSIM in St. Martin/St. Maarten?

An eSIM (embedded SIM) lets you activate a mobile data plan without inserting a physical SIM card. It works on most recent iPhones and Android phones, with prepaid data plans tailored to the length of your stay.

✔ No expensive roaming fees
✔ Activated before arrival
✔ No need to find a store after landing
✔ Works on iOS & Android

Island coverage: two networks, two realities

Saint Martin is a unique island divided into two territories:

  • 🇫🇷 Saint-Martin (French side)
  • 🇳🇱 Sint Maarten (Dutch side)

Cellular networks are separate on each side of the island. A local eSIM on the French side may not automatically work on the Dutch side — and vice versa.

What this means for you:

  • A standard local eSIM may work only on one side of the island.
  • An international or “Regional Caribbean” eSIM covers the entire island, avoiding the need to switch profiles every time you cross the border.

 

Best eSIM options to stay connected

 

1. Airalo – Regional Caribbean eSIM

Practical tips before you go

 

Install your eSIM before landing

This ensures you’re connected as soon as you exit the plane — very helpful for taxis, GPS, and local information.

Check phone compatibility

Make sure your phone supports eSIM (iPhone XR/XS and newer, recent Google Pixel and Samsung models, etc.).

Visiting both sides of the island?

Choose a global or Caribbean regional eSIM rather than a single-side local SIM for the smoothest experience.
