Yes, AeriSIM offers unlimited‑data eSIM plans that cover Liechtenstein. The plans are available for 5 G networks, are valid for between 1 and 30 days, and range in price from about $2.21 USD for a 1‑day option to $44.98 USD for a 30‑day option. For the 1‑day plan the maximum speed is 10 000 kbps; for the other durations the maximum speed caps at 5 000 kbps, and speed may be throttled if usage is very high.
These unlimited plans are subject to a fair usage policy that can reduce speeds after heavy use. If you need more specific details about how much data remains at normal speed or want to confirm whether a fair usage threshold applies, you should contact AeriSIM directly.
