If there is internet but no mobile coverage

Calling via WiFi is the ability to make calls with a mobile phone, without a mobile connection, via a WiFi connection.

In many parts of the world, the Internet reaches more places than the mobile network. You may have seen this at your vacation home or when visiting a friend in the countryside. There is solid Internet service at home, but no mobile service.

Calling via wifi has also been possible on your phone for a while now. The process is also very easy to set up. It only requires two things: a phone that can do it and a mobile provider that supports it.
