simpleSIM does not provide a plan that offers unrestricted high‑speed data for Saint Martin. The plans labeled “Unlimited” actually give a 1 GB daily allowance, with speed reduced to 1000 kbps after that limit is reached. Travelers who need more data can instead choose from simpleSIM’s fixed‑data plans, such as the 20 GB plan valid for 30 days or the 10 GB plan also valid for 30 days, which give an absolute amount of data without any speed throttling.
