RedEx eSIM does not provide an unlimited‑data eSIM plan for Luxembourg. All plans listed for Luxembourg have a fixed data cap, ranging from 1 GB to 500 GB, and after the cap is reached the speed drops to a reduced rate such as 384 kbps or 5 Mbps. Travelers who need extensive data use can choose one of RedEx eSIM’s fixed‑data plans, for example the 200 GB plan valid for 30 days, the 512 GB plan valid for 90 days, or the 100 GB plan valid for 30 days. These higher‑cap plans can be more economical for heavy data users compared to daily or multi‑day bundles.
