MobileSIM eSIM Data Plans for Martinique

MobileSIM does not provide a true unlimited data eSIM for Martinique. All plans labeled “Unlimited” actually give 3GB of high‑speed data per day; after that limit is reached, speed is reduced to 1000kbps, so the data are not unlimited.

Travelers who prefer a fixed data allowance can choose from several larger plans, such as the 20 GB plan for 30 days, the 10 GB plan for 30 days, or the 5 GB plan for 30 days. These offer a set amount of high‑speed data without a daily cap, which can be more cost‑effective for most users.

MobileSIM does not offer any eSIM plans for Martinique that include a phone number or SMS functionality. The provider sells only data‑only eSIMs for the island, so travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage for voice and text communication over the data connection.

MobileSIM offers 12 single‑country data plans for Martinique and an additional 5 multi‑country options that include Martinique in their coverage bundle. The available plans span a price range from $4.50 to $72.50, with data caps between 1 GB and 20 GB and validity periods of 3 to 30 days. Among these, customers can choose either fixed data amount plans or daily data‑cap options, depending on whether they prefer a set data allotment or a per‑day data limit.
