aloSIM does not provide a Liechtenstein eSIM plan that includes a local phone number or SMS capability. Travelers can only purchase data‑only eSIMs from aloSIM for Liechtenstein. For voice and text communications, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but it is advisable to check whether these services are accessible in Liechtenstein before buying, as some destinations may block or restrict certain apps.
