eSimfly eSIM Data Plans for Martinique

eSimfly does not provide a truly unlimited data eSIM for Martinique. The plans that carry “Unlimited” in their name allow 3 GB per day; once that limit is reached the data speed is reduced, so the plan is still capped.

Travelers who need a set amount of data might consider eSimfly’s fixed‑data options, such as the 20 GB 30‑day plan priced at $30.23 USD or the 10 GB 30‑day plan at $19.11 USD. Fixed‑data plans can be more economical for most users unless extremely heavy data consumption is expected.

eSimfly does not provide a Martinique eSIM that includes a local phone number or SMS capabilities. The only eSIMs available from eSimfly for Martinique are data‑only plans, so travelers can use services such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

eSimfly offers a total of 23 data plans that cover Martinique, split into two categories. There are 12 single–country plans that are specifically tailored for use in Martinique alone, and 11 multi‑country plans that include Martinique as part of a broader region. The available plans span a price range from about $4.10 to $118.17, with data caps that vary between 1 GB and 20 GB. Customers can choose between fixed data‑cap options and daily‑data‑cap options depending on their usage pattern; the fixed plans provide a set amount of data for the full validity period, whereas daily‑cap plans reset their allowance each day. Many of these plans also support tethering, allowing the data to be shared with other devices.
