There are certainly internet-based voice protocols, such as Skype. As long as your phone allows you to install such applications, and you can establish a wifi connection without the presence of a SIM card (which I assume would normally be the case), then yes, you could make calls over Skype or similar applications using wifi. But to be clear, this isn’t using the cellular network, at all, just the internet.
