MTX Connect does not provide an unlimited data eSIM plan for Jamaica. Every plan that the provider lists has a fixed data cap and a specific validity period.
The available alternatives are fixed‑data plans, such as the 10 GB plan that is valid for 30 days or the 4 GB plan that is valid for 14 days. These fixed‑data options can be more cost effective for most travelers unless an individual expects to use a very large amount of data that exceeds the cap.
