No, Supera link does not provide an unlimited data eSIM for Barbados. The plans listed for Barbados all have a fixed data cap of 2 GB per day, with validity periods ranging from 1 day to 10 days.
Travelers who need more data can choose a fixed‑data plan such as the 2 GB/day offers, which come in 3‑day, 5‑day, 7‑day, or 10‑day options at different price points. Selecting a larger or longer‑validity plan may be more cost‑effective for high data usage compared to unlimited services that are not available from Supera link.
