ZenSim does not provide a truly unlimited data e‑SIM plan for Martinique. The only plan that carries “Unlimited” in its name is the Martinique Unlimited STANDARD – 5 Days, which actually delivers 3 GB per day and reduces speed to 1000 kbps after the limit, so it is a fixed‑data plan rather than unlimited.
Travelers who need a larger data allowance can choose from ZenSim’s fixed‑data plans. For example, the 20 GB plan valid for 15 days costs $40.50, and the 10 GB plan valid for 30 days costs $32.40. These options provide more data and may be more cost‑effective for most users, unless a short‑term, unmetered data usage is required.
