eSimfly does not provide a truly unlimited data eSIM for Sint Maarten. The plans that carry the word “Unlimited” in their name give 3GB per day for a 7‑day period, after which the speed is reduced to 1000 kbps. This means the data allowance is capped and the connection is throttled once the daily limit is reached.
Travelers who need more data can choose eSimfly’s fixed data plans, such as the 20 GB plan valid for 30 days or the 10 GB plan also valid for 30 days. These plans offer larger data allowances without speed reduction and can be more cost‑effective for users who consume a lot of data.
