The plans labeled “Unlimited” by nextSIM for Saint Martin are not truly unlimited in the sense of offering unrestricted high‑speed data. Each of them specifies a data cap, such as 1 GB per day or 2 GB per day, and after the limit is reached the speed is throttled to either 512 kbps or 2000 kbps. Therefore a user who needs continuous high‑speed access will find these plans limited once the daily allowance is used.
For travelers who want a larger, fixed data allotment without speed reductions, nextSIM provides several standard data plans. For example, the 10 GB plan is valid for 30 days at $37.80 USD, and the 5 GB 30‑day plan costs $24.31 USD. These fixed‑data options may be more economical for heavy data users who prefer predictable speeds.
