According to DuckDuckGo: does Call on other services require cellular service

"No, you can use internet-based services to make calls without cellular service, such as Wi-Fi calling or apps like Skype and WhatsApp. These methods allow you to communicate over a Wi-Fi connection instead of relying on a cellular network."
