eSimfly eSIM Data Plans for Saint Martin

eSimfly does not provide a genuinely unlimited high‑speed data eSIM for Saint Martin.
The plans that carry the label “Unlimited” actually supply only 3 GB of high‑speed data per day; after that limit a reduced speed applies, so the data is not truly unlimited.

Travelers who need more data can choose from a range of fixed‑data eSIMs that eSimfly sells for Saint Martin. For example, a 5 GB plan valid for 30 days is available for $14.04 USD, and a 20 GB plan with 365‑day validity is offered for $84.83 USD. These fixed plans may be more cost‑effective for users who consume large amounts of data or who prefer a defined data allowance rather than a capped daily limit.

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 presents 21 independent data plans for Saint Martin, with nine covering only Saint Martin (single‑country) and twelve Defendant for multiple coverage (multi‑country). These plans range in price from about $5 to $92, and carry data caps between 1 GB and 20 GB over validity periods from three to 365 days. They are offered in two main styles: a daily‑cap option, in which the data criticism resets each day and totals a modest amount per day, and a fixed‑cap plan, where a set amount of data remains usable throughout the validity. Someqy plans also allow tethering.
