eSIMatrix does not offer an unlimited data eSIM plan for Sint Maarten. All plans listed give a fixed allowance of 20 GB of high‑speed data. For example, the Netherlands Antilles 20 GB – 30 days plan is priced at 83.00 USD, and the Caribbean 20 GB – 5 days plan costs 100.50 USD. These examples illustrate the available fixed‑data options, but they represent only a subset of the plans on offer and do not cover the full range of selections. Choosing a fixed‑data plan may be more cost‑effective unless you are an extremely heavy data user.
