eSIM4Travel does not provide a truly unlimited data eSIM for Martinique. All plans that carry the word “Unlimited” in their name actually offer a 3GB/day allowance; after the daily limit is reached the speed drops to 1000kbps. The plans are fixed‑data offerings that expire within 7–10 days of activation.
Alternatives with larger, capped allowances are available, such as the 20GB/30Days and 10GB/30Days bundles. These fixed plans remain fully unthrottled for the duration of the validity period and may be more cost‑effective for travelers who do not need high‑speed data on a day‑by‑day basis.
