eSIMCard does not provide a genuinely unlimited data eSIM for Martinique. All plans listed as “Unlimited” actually contain a capped amount of high‑speed data – 1 GB per day for the regular plan or 2 GB per day for the Plus variants – after which the speed is reduced to 500 kbps or 2 000 kbps.
If a higher data allowance is required, eSIMCard offers fixed‑data options such as the 50 GB plan for 30 days and the 35 GB plan for 30 days, both available in Martinique. These plans offer larger high‑speed data limits without the speed throttling that applies to the unlimited‑named packages, making them a more cost‑effective choice unless the traveler needs very heavy data usage.
