HelloRoam is the only provider in this comparison with a verified Saint Martin price, selling 6 plans on Orange 5G from $1.14 for 1 GB, with 10 GB at $8.56, or $0.86 per GB. Orange runs the French side alone, covering Marigot, Grand Case and Orient Bay, while Airalo publishes no Saint Martin price across its 200 destinations. Coverage stops at the border, so Dutch Sint Maarten on Chippie and UTS needs a 2nd profile.
Orange carries all 6 of HelloRoam's Saint Martin plans across the French side of the island (Saint Martin / Collectivité de Saint-Martin). The island is split between France and the Netherlands, with the French side covering Marigot, Grand Case, Orient Bay, and Anse Marcel. Orange operates under French overseas collectivity regulations, delivering European-standard service at French pricing.
The Dutch Sint Maarten side has separate carriers (Chippie/UTS) and a separate plan is needed.
