No, nextSIM does not have a true unlimited data eSIM for Jamaica. Their plans that include “Unlimited” in the name provide a fixed amount of high‑speed data, such as 1GB or 2GB, and after that limit is reached the speed is reduced—512kbps for the Standard plans and 2000kbps for the Plus plans.
Travelers who need more data can choose from nextSIM’s fixed‑data options. For example, the eSIM Jamaica 20GB 30Days Economy plan offers 20GB of high‑speed data for thirty days at a lower price than the larger “global” packages. A similar high‑capacity option is the eSIM GLOBAL 50GB 30Days Premium, which supplies 50GB of data for thirty days. Fixed data plans are often a more cost‑effective choice unless a user expects extremely heavy data usage.
