MicroEsim provides multiple eSIM plans that advertise unlimited high‑speed data for Luxembourg. These plans are labeled “Unlimited” in the data‑cap column and are valid from as little as 1 day up to 30 days, with an additional 60‑day plan that offers 60 GB of data (the high‑speed portion is capped at 128 kbps after usage expires). The unlimited plans typically allow tethering and list a maximum speed of 10 000 kbps; however, the provider may throttle speeds after heavy usage under a fair‑usage policy. Pricing for the unlimited Luxembourg eSIM ranges from about $2.50 USD for a 1‑day cap to $58.20 USD for a 30‑day cap, while the 60‑day 60 GB plan is priced at $83.64 USD. If you are concerned about possible speed restrictions, it is advisable to contact MicroEsim directly to confirm how the fair‑usage policy applies during your stay.
