ByteSIM does not offer a truly unlimited high‑speed eSIM for Jamaica. The plans listed as “Unlimited Data” actually provide a data cap of 1GB per day, after which the speed is reduced to 10240kbps, so the data is throttled rather than unlimited.
Travelers who need a larger data allowance can choose from ByteSIM’s fixed‑data plans. For example, a 10GB plan valid for 14 days costs $45.90 USD, and a 10GB plan valid for 3 days costs $47.90 USD. These plans provide a larger, continuous data supply and may be more cost‑effective for users who consume significant data while in Jamaica.
