Wiiline does not offer a true unlimited data eSIM for Luxembourg. All of the Wiiline plans listed for Luxembourg have a hard data cap, even those that carry the word “Unlimited” in their name; the caps range from 500 MB per day to 400 GB for 30 days.
For travelers who need a large amount of high‑speed data, Wiiline provides fixed‑data plans such as the 400 GB plan for 30 days or the 200 GB and 100 GB plans for 30 days. These plans give a set data allowance that must be used within the given validity and can be more cost‑effective for heavy or long‑term usage compared to multiple smaller daily or weekly bundles.
