Airalo does not offer any eSIM plans for Liechtenstein that include a phone number or SMS capability. The only options available from Airalo for this country are data‑only eSIMs.
Travelers who need to make calls or send text messages can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to certain VoIP services, so it is advisable to confirm that the apps you need will work in Liechtenstein before purchasing a plan.
