nextSIM does not provide a truly unlimited data eSIM for Liechtenstein. The plans labeled "Unlimited" in the provider’s catalogue grant only a fixed amount of high‑speed data—1 GB per day or 2 GB per day—after which the connection speed is throttled to 512 kbps or 2000 kbps respectively. Because the data allowance is capped, these plans do not offer high‑speed internet without limits.
For travelers who need more data, nextSIM offers fixed‑data options. For example, a 50 GB plan valid for 365 days costs $126.69 USD, and a 30 GB plan valid for 30 days costs $119.37 USD. These plans provide a larger data allocation without a speed reduction, which can be more cost‑effective for users who consume data heavily.
