ZenSim does not provide a truly unlimited data eSIM for Jamaica. The plans that carry “Unlimited” in the name are actually fixed‑data offers with a 3GB/day rate for five days; after each day the speed is throttled to 1000kbps.
Travelers who want high‑speed data can choose fixed data plans such as the Jamaica 20GB - 15 Days and Jamaica 20GB - 30 Days packages, each with a 20GB allowance that is valid for 15 or 30 days respectively. These plans provide a larger data capacity over a longer period compared to the 3GB/day option and can be more cost‑effective for users who need consistent connectivity while in Jamaica.
