mobineX does not provide a truly unlimited data eSIM for Luxembourg. The plans flagged with “Unlimited” actually include a high‑speed data allowance of 1 GB or 5 GB; once that allowance is reached the speed drops to 128 kbps (for the Standard plans) or 1 024 kbps (for the Gold plans). These offerings are short‑term and are valid for only 1 day.
If a longer or larger data capacity is desired, mobineX offers fixed‑data plans for Luxembourg. Examples are the 150 GB plan valid for 90 days (about $230.50 USD) and the 100 GB plan valid for 60 days (about $95.70 USD), as well as a 50 GB plan valid for 30 days (about $69.50 USD). Using one of these fixed‑data options may be more cost‑effective for travelers who need substantial data while staying in Luxembourg.
