TailSim does not provide an unlimited data eSIM plan for Luxembourg. All of its available plans for the country have a fixed data cap, ranging from 3GB to 50GB, and a validity period of 15 to 30 days.
Travelers who need a large amount of data can choose from TailSim’s fixed data plans. For example, the 50GB plan is valid for 30 days and the 20GB plan is also valid for 30 days. These fixed data plans can be more cost‑effective for most users, unless a traveler requires an extremely high data volume that would exceed the largest available bundle.
