ByteSIM does not provide a truly unlimited data eSIM for Luxembourg. The plans that carry the word “Unlimited” in their name actually offer 1GB per day of high‑speed data, after which the speed is reduced to 10 000 kbps. Therefore, these plans are not unlimited in the sense of providing unlimited high‑speed data.
If a traveler needs a larger data allowance, ByteSIM offers fixed data plans such as 50GB for 3, 5, 7, 10, or 15 days. These plans give a substantial amount of high‑speed data within a set validity period and can be more cost‑effective for most users.
