eSimfly eSIM Data Plans for Sint Maarten

eSimfly does not provide a true unlimited data eSIM for Sint Maarten. All plans that use the word “Unlimited” are actually capped at a fixed amount of high‑speed data; for example, the Netherlands Antilles Unlimited 1 Day plan offers 1 GB of 4G data, and the Caribbean Islands Unlimited 7 Day plan provides 3 GB per day before the speed is throttled. If you need a larger supply of high‑speed data, eSimfly offers fixed‑data alternatives. One example is the Discover Global 20 GB plan valid for 365 days, priced at about $84.83 USD, and another is the Sint Maarten (Dutch Part) 10 GB plan valid for 30 days at roughly $70.89 USD. Fixed data plans can be more cost‑effective for travelers who are heavy data users, as they avoid the speed reduction that occurs when the capped limit is reached.

eSimfly does not provide Sint Maarten eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for Sint Maarten. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging.

eSimfly provides five single‑country plans for Sint Maarten and an additional 38 multi‑country coverage options that include the island. The available plans span a price range from about $7.69 to $221.94, with data caps between 1 GB and 20 GB and validity periods from one to 365 days. Travelers can choose from fixed data‑cap packages, which offer a set amount of data for the entire validity period, or daily‑cap options that reset each day, giving more flexibility for short stays. Tethering is permitted on many of the offerings.
