Wi-Fi calling expands your coverage to places where the mobile network isn’t as strong. Google Fi routes your call over whichever network provides you with the best experience.
Tips:
- If your Wi-Fi connection isn’t as strong or stable as your cellular connection, your call might go over cellular.
- To make best use of Wi-Fi calling, connect to Wi-Fi whenever it’s available and keep your Wi-Fi turned on.
- Wi-Fi calling may not work if you have a virtual protected network (VPN) turned on. To ensure that Wi-Fi calling works, turn off your VPN or update your VPN settings so that the Google Fi app can bypass the VPN.
