eSimfly eSIM Data Plans for Martinique

eSimfly does not offer a truly unlimited data eSIM for Martinique. Plans that carry “Unlimited” in the name actually have a 3 GB/day data cap, so after that limit the speed is typically throttled. For travelers who need more data without a daily cap, eSimfly offers fixed‑data options such as the 20 GB plan valid for 30 days priced at $30.23 USD and the 10 GB plan for 30 days priced at $19.11 USD. These fixed‑data plans can be more cost‑effective for users who are heavy data consumers or who prefer a predictable data allowance.

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.
