Flysimio’s eSIM plans for Croatia do not include a phone number or SMS functionality. The provider offers only data‑only eSIMs for this destination, so travelers cannot receive or send standard SMS messages through the eSIM.
With a data‑only plan, VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection to make calls and send text. However, some destinations may block or restrict access to these apps, so travelers should verify that the messaging and calling services they rely on are available in Croatia before purchasing.
