eSimfly does not provide a truly unlimited data eSIM for Saint Martin. The plans that carry the word “Unlimited” in their name actually have a fixed data allowance: 3 GB per day for the French part of Saint Martin or 35 GB for the international version, and after the limit is reached the speed is throttled to 1000 kbps. Therefore these plans are not unlimited in the sense of offering high‑speed data without limits.
Travelers who need a large amount of data can choose from eSimfly’s fixed data plans. For example, a 5 GB plan valid for 30 days or a 10 GB plan valid for 30 days provide substantial data, and the 35 GB international plan valid for 30 days offers an even larger allowance. These fixed data plans can be more cost‑effective for users who consume a lot of data.
