No, nextSIM does not provide a truly unlimited high‑speed data eSIM for Liechtenstein. All of its plans listed for Liechtenstein have a fixed data allowance, such as 1 GB per day or 2 GB per day, and once the allowance is reached the connection speed is reduced to a specified lower rate (for example 512 kbps or 2000 kbps). The term “unlimited” in the plan names is a marketing label rather than an actual uncapped data volume.
If a traveler needs a larger data budget, nextSIM offers fixed‑data packages. For example, a 100 GB 30‑day plan costs $63.55, and a 50 GB 30‑day plan is $32.09. These fixed plans can be more cost effective for heavy data usage than the capped “unlimited” options.
