Voice calls over Wi-Fi

As its name suggests, Wi-Fi Calling or VoWiFi (short for Voice over Wi-Fi) is a feature that allows you to call or send text messages over Wi-Fi.

Calling over Wi-Fi and the Internet is nothing new. For years, we have used applications and services such as Skype Y WhatsApp to send messages or make calls over the Internet. But what separates Wi-Fi calling from these apps is just the means of last-mile connectivity. Everything else stays the same. Instead of using cellular service to send or receive voice calls from your carrier’s network, your phone uses Wi-Fi. You still use the same dialer, the same texting app, and the same contact list. Everything works perfectly.

Once you’ve turned on Wi-Fi calling on your smartphone, it turns on automatically when your cellular service is limited or unavailable. All your calls and texts are routed over the Internet using Wi-Fi. Depending on the carrier, your phone may even keep Wi-Fi Calling active when you’re in an area with good cellular service but connected to a Wi-Fi network. It helps carriers reduce network congestion while providing you with better voice service.

However, when you go out of Wi-Fi coverage, calls and texts return to the cellular network. This all happens without a hitch and ideally you shouldn’t experience dropped calls or other issues due to the switch.
