yaySIM does not provide an Austria eSIM plan that includes a phone number or SMS capability. All available Austria eSIM options from this provider are data‑only plans.
Travelers who need to make voice calls or send text messages can typically use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict access to certain apps or VoIP services, so it is advisable to confirm that the applications you rely on are accessible in Austria before purchasing a plan.
