Wi-Fi Calling for Beginners + 3 Benefits
You may have heard the term Wi-Fi calling used by your cell phone provider, your internet provider, or even other people. It’s a common term that refers to using an internet connection to make phone calls, but there’s a bit more to it.
Wi-Fi calling is the use of the Internet, via a wireless Internet network, to make phone calls on a mobile device. The ability to send and receive Wi-Fi calls is built into most smartphones today, and most mobile service providers, including AT&T, Verizon, T-Mobile and others, offer Wi-Fi calling for free (domestic).
Additionally, Wi-Fi calling uses a small amount of bandwidth (around 1MB for voice calls and 6-4MB for video calls), so you don’t need a fast internet connection to take advantage of Wi-Fi calling.
