Looking for eSIM suggestions for St. Martin/Sint Maarten

Is there one that works on both the French and Dutch sides of the island?

While not a travel eSIM, you can get an eSIM from Flow which has service on both sides of the island.

Flow not available in SXM. Per current website.

We could not find one for both sides. We used Airalo for the French side and it worked perfectly.

What doesnt work in Maho, dutch side, st maarten??? Gigsky. Stay away!

Ha did ai find this one? hope so to save all the trouble for the next tourists.

Digicel works on St Martin but not Sint Maarten.

Flow is what Chippie used to be. When we were there in December/January, it worked fine. There are several Flow stores on both sides of the Island.

We have a SIM from Chippie and our phone works fine all over the island, both in Saint-Martin FWI and Sint Maarten. You can purchase a Chippie SIM from a U.S. based outfit or buy one on the island at their office or very likely at the phone store located at the Bush Road Carrefour market. Now that many newer phones use eSIMs, I would assume that Chippie can supply those, too.
