How do I activate VoWifi?

It is very simple, all you need is a compatible smartphone and a Wi-Fi connection.

During your call, your smartphone will automatically connect to the most suitable network to give you the best possible calling experience. If your mobile coverage is good, you will use the 4G network. Is the 4G coverage too weak? Then the device will switch to Wi-Fi and your phone call will continue. When leaving the area with weak coverage, the device will switch back automatically and your call continues.

VoWifi is not available on all smartphones

Here you will find a list of devices. You can also check whether your device supports this via the settings:

• Android: Open the Phone app (the standard app for making calls) > More options > Settings >
  Move the slider next to Wi-Fi Calling to the right to activate it or to the left to deactivate it.
• iPhone: Go to Settings > Mobile network (or Cellular) > Wi-Fi Calling > activate or deactivate Wi-Fi Calling on this iPhone. If a pop-up appears, tap Enable. Reboot your device.

Are these settings not visible? That probably means that your smartphone does not support VoWifi.
VoLTE might be a good solution if it's available on your device. More info can be found here.
