Avelis eSIM does not provide a Croatia eSIM plan that includes a phone number or SMS capability. Only data‑only plans are available, so travelers can use the eSIM for internet access while relying on VoIP applications such as WhatsApp, Telegram, or iMessage for voice and text. These apps typically function over the data connection, but some destinations may block or restrict specific VoIP services, so it is advisable to confirm that the preferred apps are accessible in Croatia before purchasing an Avelis plan.
