eSIMCard eSIM Data Plans for Martinique

eSIMCard does not provide a truly unlimited data eSIM for Martinique. Plans that include “Unlimited” in their name are capped—for example, a 1‑day plan gives only 1GB of high‑speed data and slows to 500 kbps once that limit is reached, while a 1‑day “Unlimited Plus” plan offers 2GB before dropping to 2 Mbps. Travelers who require more data can choose from eSIMCard’s fixed‑data options instead. Handpicked examples include a 50GB plan valid for 30 days priced at $31.39 USD, a 100GB unthrottled plan for 180 days costing $99.13 USD, and a 35GB plan for 30 days also at $31.39 USD. These fixed‑data plans provide higher data allowances and no speed throttling, which may be more cost‑effective for heavier data users.

eSIMCard does not provide a Martinique eSIM that includes a local phone number or SMS capability. Travelers can purchase only data‑only eSIMs, and can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

eSIMCard offers 21 single‑country plans that cover Martinique and 42 multi‑country plans that include Martinique as one of the destinations. The available plans range in price from $3.25 to $430.64 and provide data caps between 1 GB and 100 GB. Some plans feature a daily data cap, meaning the data allowance resets each day, while others use a fixed data cap, giving a single total amount of data for the entire validity period.
