MobileSIM eSIM Data Plans for Martinique

MobileSIM does not provide a fully unlimited high‑speed data plan for Martinique. The plans labelled “Martinique Unlimited data for X days” deliver 3 GB per day and after the allowance is used the speed drops to 1000 kbps, so the data is capped. Those plans are not truly unlimited.

Instead, MobileSIM offers fixed‑data plans that may be more cost‑effective. For example, the 20 GB plan for 30 days costs $42.00 USD, and the 10 GB plan for 30 days is $26.00 USD. These plans give a set amount of high‑speed data each day without a reduced‑speed threshold.

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).
