Can I make calls over WiFi?
WiFi calling allows you to make and receive calls, texts and more over your wireless network if your cellular service isn’t strong enough or isn't available. You can make and receive calls using your WiFi network with our iPhone, Android and desktop apps. Inbound calls over WiFi will count against your plan's minutes, but outbound WiFi calls are free.
To use WiFi calls with the Grasshopper mobile apps, you must first enable it.
