eSimfly eSIM Data Plans for Saint Martin

eSimfly does not provide a truly unlimited high‑speed data eSIM for Saint Martin. All of its plans for the island are limited to a daily allowance of 3 GB, after which the speed is reduced (the exact throttled speed is not stated). Because the plans are capped, eSimfly’s offerings are classified as fixed‑data plans rather than unlimited‐data plans.

If a traveler needs more data, eSimfly offers several fixed‑data alternatives that cover Saint Martin. For example, the Discover Global 20 GB plan provides 30 days of high‑speed data for $40.88 USD, and the Discover Global 20 GB 365‑day plan offers the same amount of data for $76.05 USD. Another option is the Caribbean Islands 10 GB plan, valid for 30 days at $91.65 USD. These fixed‑data plans can be a more cost‑effective choice unless a user is an extremely heavy data consumer.

eSimfly does not provide a Saint Martin eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are available for Saint Martin from this provider. Travelers can still use internet‑based messaging and calling applications such as WhatsApp, Telegram, or iMessage over the data connection, but there is no native phone number or SMS service with the eSIM.

eSimfly offers nine single‑country data plans that include coverage for Saint Martin, along with an additional sixteen multi‑country plans that also cover the island. The plans vary between fixed data packages of 1 GB up to 20 GB and daily data cap options that allow a set amount of data to be used each day, giving travelers flexibility in how they consume data. Prices for Saint Martin plans range from around $4.38 to roughly $91.65, while data caps span from a single gigabyte to combinations that reach 20 GB, making the options suitable for short trips or longer stays.
