CloudOn eSIM eSIM Data Plans for Luxembourg

CloudOn eSIM does not provide a truly unlimited data eSIM for Luxembourg. All plans that carry “Unlimited” in their name actually offer a fixed daily data allowance—3 GB/day for Luxembourg‑only plans and 2 GB/day or 5 GB/day for broader Europe or global plans—after which the speed is reduced to 1 Mbps.

If a traveler needs a large, unthrottled data allowance, CloudOn eSIM offers fixed data plans such as the Luxembourg 50GB 30 days plan or the Luxembourg 20GB 30 days plan, which provide a set amount of high‑speed data for a 30‑day validity period. These fixed plans can be more cost‑effective for users who require substantial data without the speed reduction that applies to the “Unlimited” plans.

CloudOn eSIM does not provide eSIM plans that include a phone number or SMS in Luxembourg, offering only data‑only eSIMs for that destination. Travelers can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for calls and messaging, but some destinations may block or restrict these apps, so it is advisable to confirm that the apps you rely on are accessible in Luxembourg before purchasing.

CloudOn offers a total of 35 data plans for Luxembourg, split into 11 single‑country (Luxembourg‑only) plans and 24 multi‑country plans that include Luxembourg among their coverage zones.
The available plans range in price from about $3.49 to $126.99 and provide data caps from 1 GB up to 50 GB, with validity periods between 3 and 30 days. On the single‑country side plans are primarily fixed‑data‑cap options, while the multi‑country offerings include both fixed caps and daily data‑cap varieties, allowing travelers to choose between a set amount of data or a daily allowance that resets each day.
