Bordersim does not provide an unlimited data eSIM plan for Martinique. The available options are fixed data plans, such as the Martinique 20GB 30Days plan, which offers 20GB of high‑speed 5G data for 30 days, and the Martinique 10GB 30Days plan, which offers 10GB for the same period. These plans include tethering and are priced at $13.49 USD and $7.49 USD respectively. Choosing a fixed data plan can be more cost‑effective for most travelers, unless a user requires a truly unlimited data allowance.
