Kolet eSIM Data Plans for Luxembourg

Kolet does not provide a true unlimited‑data eSIM for Luxembourg. The plans that include “UNLIMITED” in their name give 5GB per day and then throttle speed to 1024 kbps, so they have a hard data cap. If you want more data without the throttling, you can choose from the fixed‑data options such as the 20GB plan for 30 days, which offers 20GB of high‑speed data for that period, or the 10GB plan for 30 days. These fixed plans give a larger total data allowance and avoid a speed reduction, and may be more cost‑effective for travelers who need consistent high‑speed connectivity.

Kolet does not provide a Luxembourg eSIM that comes with a local phone number or SMS capability. The provider offers only data‑only plans. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but availability can vary because some destinations may block or restrict these services. It is advisable to confirm that the apps you rely on are accessible in Luxembourg before purchasing a Kolet plan.

Luxembourg has 13 single‑country plans and 31 multi‑country plans available from Kolet. The single‑country options typically feature a fixed data amount that ranges from 1 GB to 10 GB, with prices between roughly $4 and $60. The multi‑country plans cover Luxembourg in addition to other European destinations and offer data caps from 1 GB up to 20 GB, with prices spanning about $5 to $105. Fixed‑cap plans provide a set amount of data for the entire validity period, while daily‑cap plans limit the amount of data that can be used each day before a speed reduction to 1 Gbps applies.
