Saily does not offer a truly unlimited high‑speed data plan for Luxembourg. The only plan that carries the word “UNLIMITED” in its title, Luxembourg UNLIMITED 15 days, actually provides 5 GB per day of high‑speed data and then reduces the speed to 1024 kbps. This means that after the daily allowance is reached the connection is throttled.
Travelers who need a larger data allowance can choose from Saily’s fixed‑data plans. For example, the Luxembourg 20GB 30 days plan gives 20 GB of high‑speed data for 30 days, while the Luxembourg 10GB 30 days plan offers 10 GB for the same period. These options provide full‑speed data until the data cap is reached, and can be more cost effective for most users than a plan with a daily limit and throttling.
