How do I enable or disable WiFi calling?

When WiFi calling is enabled, your calls from the mobile app will default to using WiFi as long as there is a strong enough signal. To use WiFi calling with the Grasshopper iOS or Android apps, go to Settings > WiFi Calling > Enable.

WiFi calling is automatically enabled on the desktop app, as it will always uses your Internet connection to make and receive calls (whether LAN or WiFi).
