eSIMatrix does not provide an unlimited‑data eSIM for Luxembourg. All of the plans available for Luxembourg feature a fixed data cap of 20 GB. Buyers can choose from variations in validity, such as a 20 GB plan lasting 5 days, 10 days, 15 days, 20 days, or 30 days, with the Luxembourg‑only 20 GB for 30 days or the Europe‑wide 20 GB options.
For travelers who need a larger capacity than 20 GB but are not extremely heavy data users, these fixed data plans can be a more cost‑effective option than resorting to an unlimited plan elsewhere.
