JamboSim eSIM Data Plans for Martinique

JamboSim does not provide a truly unlimited high‑speed eSIM for Martinique. Plans that carry the word “Unlimited” in their name supply 3 GB per day of 4G/5G data; once the daily limit is reached the connection is throttled to 1000 kbps. If a traveler needs more data before encountering the speed reduction, they can choose one of JamboSim’s fixed data plans. For example, a 20 GB plan valid for 30 days costs $16.99 USD, while a 10 GB plan for the same period is available for $10.99 USD. These fixed‑data options allow users to avoid throttling and may be more cost‑effective for heavy data consumers.
