RedSim eSIM Data Plans for Martinique

RedSim does not provide a truly unlimited data eSIM for Martinique. The plans that carry the “Unlimited” name give 3 GB of high‑speed data per day and then reduce the speed to 1 Mbps for the remainder of the day, so the data allowance is capped.

Travelers who need more data can choose from RedSim’s fixed data plans. For example, a 20 GB plan valid for 30 days costs $31.45, and a 10 GB plan for the same period costs $19.97. There is also a 10 GB/day plan that lasts one day for $11.98. These plans offer larger data allowances and may be more cost‑effective for heavy data users.

RedSim does not offer a Martinique eSIM that includes a phone number or SMS function; only data‑only plans are available.

Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging. Some destinations may restrict or block certain apps or VoIP services, so it is a good idea to verify that the specific apps a traveler relies on are accessible in Martinique before making a purchase.

RedSim offers a total of 41 eSIM data plans for Martinique, comprising 36 plans that cover only Martinique and 5 plans that combine Martinique with other destinations. The available plans range in price from about $1.88 to $359.40 and provide data caps between 1 GB and 20 GB. Some plans feature a fixed data amount for the full validity period, while others reset a daily data cap, giving travelers the flexibility to choose between a set amount of data for the entire stay or a daily allowance that replenishes each day.
