Stellar eSim does not provide an Austria eSIM that includes a phone number or SMS capability. All available plans for Austria from this provider are data‑only, so travelers cannot receive or send traditional voice calls or SMS text messages through the eSIM.
Customers who need communication while traveling can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so it is advisable to confirm that the messaging or calling apps you rely on are accessible in Austria before purchasing a plan.
