4S eSIM eSIM Data Plans for Luxembourg

4S eSIM does not provide a genuinely unlimited data eSIM specifically for Luxembourg. The plans listed as “Unlimited” all contain a fixed data cap—such as 3 GB, 5 GB, 10 GB, 20 GB, 30 GB or 50 GB over a set validity period—and once the cap is reached the speed is throttled to 1000 kbps. Travelers who need more data can choose one of the fixed‑data plans that 4S eSIM offers; for example, a 50 GB plan is available for 5 days ($24.01 USD) or 7 days ($25.31 USD). These fixed plans provide straightforward, cost‑effective options for users who want high‑speed data for a defined period without the reduced‑speed clause that applies to the “Unlimited” titles.

4S eSIM currently does not offer any plan that includes a local phone number or SMS capability for Luxembourg. All available plans are data‑only and can be used for internet access, messaging, and voice or video calls through VoIP applications such as WhatsApp, Telegram, or iMessage.

4S eSIM has 54 single‑country data plans available for Luxembourg and an additional 108 multi‑country plans that include Luxembourg. The plans vary from just $1.42 to roughly $195.83, with data caps ranging from 714 MB up to 50 GB. Some options provide a fixed data amount, while others apply a daily data cap or reduced speed for the last 1 000 Mbit.
