How to Make Wi-Fi Calls on Android™ Smartphones (2:20)
Select phones are capable of Wi-Fi Calling, allowing you to make and receive domestic or international calls over a Wi-Fi network, even if you're not in Verizon coverage.
An even better advantage is if you have service issues while indoors like dropped or failed calls, Wi-Fi calling helps with those problems by routing your call over your internet connection securely and with amazing clarity!!
To begin using Wi-Fi calling, you'll need a compatible device that's connected to a Wi-Fi network, and on an Android device HD Calling must be enabled.
After enabling, you'll be asked to enter an address in order to appropriately route emergency calls.
Then, all you have to do is dial!
Once the feature is enabled you'll know your call is connecting over Wi-Fi by the "Wi-Fi calling" icon seen here. Calls will use the cellular network if available to provide you the most reliable experience.
Wi-Fi calling is also a great option when traveling outside the United States. With any Wi-Fi calling-capable Android device, you can set your device to prefer wifi calling by:
Apps icon > Settings > Advanced Calling
Tap Wi-Fi Calling
Tap When Roaming
Tap Prefer Wi-Fi
Now when making calls over Wi-Fi:
Calls to US numbers are not billed (except for 411 or other premium calls).
Calls to international numbers are billed according to your international long distance plan.
