eSimfly eSIM Data Plans for Luxembourg

eSimfly does not provide a truly unlimited data eSIM for Luxembourg. All plans that use “Unlimited” in their name carry a fixed daily allowance—either 1GB or 3GB per day—for the duration of the validity period. After the daily limit is reached, the speed is typically throttled to a lower level, although the exact reduced speed is not specified.

If you need a larger data allocation, eSimfly offers fixed‑data options such as a 100GB plan valid for 30 days or a 50GB plan also valid for 30 days. These plans give you a set amount of high‑speed data without daily caps, which can be more cost‑effective for heavy‑usage travelers compared with the “Unlimited” plans.

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 offers 17 single‑coverage data plans and 75 multi‑coverage data plans that include Luxembourg. The single‑coverage plans give you a fixed total data amount, while the multi‑coverage plans allow you to use your data on multiple countries, with the same total data allocation. In addition, a portion of the plans are daily data‑cap, meaning you get a set amount of data each day and the cap resets. Across all plans the price range is roughly $1.43 to $331.48, and the data caps range from 1 GB to 100 GB.
