NextSIM’s plans that carry the “Unlimited” label for Saint Martin actually provide a capped amount of high‑speed data: each plan offers either 1 GB or 2 GB of fast data, after which the speed drops to 512 kbps or 2000 kbps respectively. Because there is a data cap, these plans are not truly unlimited in the sense of providing unrestricted high‑speed internet.
If a user needs a larger amount of data, nextSIM offers fixed‑data eSIMs such as the 50 GB plan for 30 days or the 20 GB plan for 30 days. These fixed‑data options provide a larger volume of high‑speed data, though they come at a higher cost. Choosing a fixed‑data plan can be a more cost‑effective solution for travelers who require substantial data usage.
