AeriSIM does provide unlimited‑data eSIM plans that cover Luxembourg. The provider lists several “Europe 32 Countries Unlimited eSIM” options with the data cap marked as Unlimited. Validity ranges from 1 day to 30 days, with prices from $2.21 USD for a 1‑day plan to $44.98 USD for a 30‑day plan. All are delivered over 5G, and each plan notes that speeds may be throttled; the maximum listed speed is 10000 kbps for the 1‑day plan and 5000 kbps for the longer‑duration options.
Because the plans are subject to a fair‑usage policy, high‑volume users may experience reduced speeds after a certain threshold. Travelers who expect heavy use should contact AeriSIM directly to confirm the fair‑usage limits and the amount of data that can be consumed at normal speed before throttling occurs.
