MicroEsim does not provide a truly unlimited high‑speed data eSIM for Jamaica. The plans that list “Unlimited” in their name give only 1 GB of high‑speed data per day and throttle the speed to 5000 kbps once that daily limit is reached.
The fixed data plans that offer the largest high‑speed allowances include “Americas & Caribbean eSIM 33 Countries – 3 Days / Total 50 GB” and “Americas & Caribbean eSIM 33 Countries – 5 Days / Total 50 GB”, each offering 50 GB of high‑speed data for the specified validity period before speed is reduced to 128 kbps. These options allow relatively large amounts of unthrottled data for travelers who need more than the daily 1 GB limit.
