TailSim eSIM Data Plans for Luxembourg

TailSim does not provide a truly unlimited data eSIM for Luxembourg. The plans that carry the word “Unlimited” in their name actually offer 3 GB per day; once that daily quota is reached the speed is throttled to 1000 kbps. Therefore, the data is not unlimited in the sense of an unrestricted high‑speed allowance.

If you need a larger data allowance, TailSim offers fixed data plans for Luxembourg. Examples include a 50 GB plan valid for 30 days, a 20 GB plan for 30 days, a 10 GB plan for 30 days, and a 5 GB plan for 30 days. These fixed data plans can be more cost‑effective for most travelers unless you expect to use data at a very high volume.

TailSim does not offer a Luxembourg eSIM plan that includes a phone number or SMS capability. The provider only sells data‑only eSIMs for this destination. Travelers who need communication services can use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, but they should verify that the apps they rely on are accessible in Luxembourg before purchasing, as some destinations may block or restrict certain services.

TailSim provides 14 multi‑country data plans that include coverage in Luxembourg, while no single‑country plans are offered for the country. The available plans vary from approximately $4.99 to $85.50 and include data caps from 1 GB up to 50 GB for validity periods of 3 to 30 days. Some plans feature a daily data cap—limiting the amount of data usable each day—while others offer a fixed data cap—providing a set quantity of data for the entire validity period.
