RedSim eSIM Data Plans for Martinique

RedSim does not provide a true unlimited‑data eSIM for Martinique. The plans that include “Unlimited” in the name give a maximum of 3 GB of high‑speed data per day; after that the speed is throttled to 1 Mbps. The only alternatives are fixed‑data bundles that can be used within a set validity period, such as the 20 GB 30‑day plan which costs $17.51 USD and offers 5G coverage in Martinique.

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 provides 21 single‑country data plans and 5 multi‑country plans that include Martinique. The available plans span a price range from about $1.90 to $62.02 and offer data caps between 1 GB and 20 GB. Some plans feature a fixed data amount that is delivered over the validity period, while others impose a daily data cap that limits usage each day; the catalog lists 12 fixed‑data plans and 14 daily‑cap plans. This gives travelers a broad selection of options to suit different budgets and usage needs.
