No, Supera link does not offer an unlimited data eSIM for Jamaica.
All plans listed for Jamaica from Supera link have a data cap of 2GB per day. The available options provide 2GB/day for 1 day, 3 days, 5 days, 7 days, and 10 days, with prices ranging from $8.34 to $81.01 USD. Because there are no unlimited plans, travelers who need more data may choose one of the fixed‑data options. Fixed plans can be more cost‑effective than buying a large unlimited package, especially for moderate data usage; however, very heavy data consumers might still prefer a plan with higher limits.
