Viasimo does not provide a truly unlimited high‑speed data eSIM for Luxembourg. The provider’s “Unlimited” plans allot 2GB per day at full speed and then throttle the connection to 1 Mbps until the next day. These fixed data plans are available in a range of durations, such as the Luxembourg eSIM Unlimited 30 days (2GB/day, 30 days, $50.99) and the Luxembourg eSIM Unlimited 90 days (2GB/day, 90 days, $149.99). For users who need larger high‑speed data allowances, Viasimo also sells fixed‑data plans like the Luxembourg eSIM 50 GB for 180 days (50GB, 180 days, $47.99). Selecting a fixed data plan can be more cost‑effective for heavy data users compared to the throttled “Unlimited” options.
