Avelis eSIM does not provide an unlimited data eSIM for Luxembourg. All of the plans listed for Luxembourg have a fixed data cap, with the largest offering 50GB for 180 days and the smallest offering 20GB for 30 days.
Travelers who need a large amount of data can choose one of these fixed data plans, such as the 50GB plan valid for 180 days or the 50GB plan valid for 30 days. Fixed data plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would benefit from a truly unlimited option.
