MobileSIM eSIM Data Plans for Martinique

MobileSIM does not provide a truly unlimited data eSIM plan for Martinique. The plans that carry the name “Unlimited” actually give a fixed allowance of 3GB per day; after that limit is hit, the speed is reduced to 1000 kbps.

If a user needs a higher volume of high‑speed data without the daily cap, MobileSIM offers fixed‑data plans instead. For example, a 20 GB plan valid for 30 days costs $42.00 USD, and a 10 GB plan with the same validity is priced at $26.00 USD. These fixed plans can be more cost‑effective for travelers who are heavy data 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 lists 22 individual data‑plan options that cover Martinique: 12 that are restricted to a single country and 10 that span multiple destinations. The available plans span prices from about $2.30 to $165 and data allocations from 200 MB up to 60 GB. Some of these plans charge a daily data cap (6 plans) while the others provide a fixed data amount for the entire validity period (16 plans).
