gosimless does not provide any unlimited data eSIM plans for Luxembourg. All of the available offerings are fixed data plans that give a specific amount of high‑speed data for a set period.
The largest options list 50 GB of data, which can be used within 31, 30 or 180 days, depending on the plan. For example, the Luxembourg 50 GB – 180 days plan costs $37.49 USD, and the Europe (31 areas) 50 GB – 31 days plan costs $26.49 USD. Choosing a fixed data plan can be more cost‑effective for most travelers unless they expect to use data beyond the plan’s limit.
