NextSIM does not provide a truly unlimited data eSIM for Sint Maarten. All plans labeled “Unlimited” in the catalogue actually limit high‑speed data to 1 GB per day in the Standard plan and 2 GB per day in the Plus plan; once these limits are reached the speed is throttled to 512 kbps or 2000 kbps. Consequently, the plans are subject to a data cap rather than offering unhindered high‑speed internet.
If a user needs a larger, fixed allowance, nextSIM sells several non‑unlimited options that cover Sint Maarten. Examples include the eSIM 20GB 30 Days Caribbean plan, which supplies 20 GB of high‑speed data for 30 days, and the eSIM GLOBAL 50GB 30Days Premium, which provides 50 GB for the same period. These plans may be more cost‑effective for travelers who consume a lot of data but do not require the high‑speed data to be unlimited.
