eSimfly eSIM Data Plans for Luxembourg

eSimfly does not offer a truly unlimited data eSIM for Luxembourg. All plans that carry the word “Unlimited” in their name actually provide a fixed amount of high‑speed data—typically 1 GB day or 3 GB day—and after that limit is reached the speed is reduced. For travelers who need more data without a strict daily cap, eSimfly offers fixed‑amount plans, such as the 100 GB plan valid for 30 days or the 50 GB plans that last 30 days or 180 days. These options provide a larger, unthrottled data allowance and can be more cost‑effective for heavy data usage.

eSimfly does not provide a Luxembourg eSIM that comes with a local phone number or SMS capability. Travelers looking for a data‑only eSIM can purchase one from eSimfly, but they cannot make or receive traditional voice calls or SMS over a dedicated mobile number with that provider. Instead, users can rely on internet‑based messaging and calling services such as WhatsApp, Telegram, or iMessage, which work over the data connection.

eSimfly provides 16 single‑country coverage plans that are valid in Luxembourg. In addition, it offers 60 multi‑country coverage plans, many of which include Luxembourg as one of the destinations. The available data plans vary in price from about $1.50 up to $348.94 and in data cap from 1 GB to 100 GB, with validity periods ranging from a single day to 365 days. There are 21 daily data‑cap options and 55 fixed data‑cap options; some of the plans also allow tethering.
