TailSim does not offer a Croatia eSIM that includes a phone number or the ability to send or receive SMS. All of TailSim’s available plans for Croatia are data‑only, so travelers will not receive a local number. However, they can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. Note that some destinations may block or restrict access to particular apps or VoIP services, so travelers should verify that the services they rely on are accessible in Croatia before purchasing.
