Is roaming free in Liechtenstein with EU or Swiss SIM cards using CoreESIM?

The roaming situation in Liechtenstein for EU or Swiss SIM cards is complex. While Liechtenstein is part of the EEA, meaning EU 'Roam Like at Home' rules generally apply, its unique customs and telecommunications union with Switzerland (a non-EU country) introduces variability. Signal handover between Swiss and Liechtenstein networks can lead to unexpected roaming charges, particularly for non-Swiss EU SIMs. CoreESIM advises a dedicated plan for Liechtenstein to avoid potential bill shock and ensure consistent data rates.
