When Wi-Fi Calling is on, the Wi-Fi networks
you are connected to will be used for your calls.
You can make calls over a Wi-Fi connection even
if your wireless signal is low, and best of all, if you have a
limited Talk plan, Wi-Fi Calling doesn't count against your
minutes.

Can I make and receive Wi-Fi calls over a public Wi-Fi network?
Yes, many public Wi-Fi networks allow Wi-Fi calling. Some require extra steps to connect to the network.
Before making calls, ensure your device is connected to the public Wi-Fi network and has Internet access. If you are unable to place calls, check your Web browser for additional steps.
