nextSIM eSIM Data Plans for Saint Martin

nextSIM does not have a true unlimited high‑speed data eSIM for Saint Martin. All plans labelled “Unlimited” provide a fixed amount of 3G/4G data—1 GB per day in the Standard line or 2 GB per day in the Plus line—and once that amount is reached the speed is throttled to 512kbps or 2000kbps respectively.

If you need more data, nextSIM offers fixed‑data options such as a 10 GB 30‑day plan for $35.61 USD, a 20 GB 30‑day plan for $63.63 USD, or a 50 GB 30‑day plan for $143.69 USD. These plans give you high‑speed data without the post‑cap speed reduction, which may be more cost‑effective for heavier users.

nextSIM does not provide an eSIM for Saint Martin that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for this destination.

Users who need voice or text communication can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

nextSIM lists 25 single‑country data plans that can be used in Saint Martin, with no multi‑country bundles available for that destination. The plans cover a wide range of prices—from $4.74 to $413.47 USD—and data allocations from 1 GB to 50 GB over validity periods of 1 to 30 days. Within these 25 offerings, 13 provide a fixed data amount that is shared during the entire validity, while the remaining 12 offer a daily data cap that resets each day, giving users a steady per‑day allowance. This structure allows travelers to choose between a one‑time data purchase or a recurring daily allowance depending on their usage pattern.
