Stellar eSim does not offer a plan that provides truly unlimited high‑speed data for Saint Martin. The plans that carry the label “Unlimited” actually include a 3GB data cap and vary in validity from 1 day to 300 days.
Travelers who need more data can choose one of Stellar eSim’s fixed data plans. For example, a 20GB plan is available for 20 days or 30 days, each priced at $6.29, and an 18GB plan is also available for 20 days at $5.63. These fixed data plans give a larger, clearly defined data allowance and may be more cost‑effective for most users.
