What Wi-Fi-Calling Means

You may have heard the term Wi-Fi calling used by your mobile phone service provider, your internet provider, or even other people. It’s a common term that references utilizing an internet connection to make phone calls, but there’s a little more to it than that.

Wi-Fi calling means using the internet, via a wireless internet network, for phone calls on a mobile device. The ability to send and receive Wi-Fi calls is built into most smartphones today, and mostmobile service providers , including AT&T, Verizon, T-Mobile, and others, provide Wi-Fi calling for free (domestically).

What’s more, Wi-Fi calling uses a small amount of bandwidth (about 1 MB for voice calls or 6-4 MB for video calls), so it’s unnecessary to have a high-speed internet connection to take advantage of Wi-Fi calling.

Why People Use Wi-Fi Calling

Most of those service providers mentioned above have also enabled switching calls from a mobile network to a Wi-Fi network to carry call data seamlessly.

So, if you start a phone call while you’re in your car, that call would use the mobile network, but when you get home, and your phone automatically reconnects to your wireless home internet, it ‘switches’ to the internet network.

This switch happens for two reasons:

• It increases network coverage. For phones with Wi-Fi calling enabled, it is possible to switch a call to an open Wi-Fi network if the carrier network signal becomes weak.
• To reduce the amount of data that is traveling over mobile networks. By reducing the congestion on mobile networks, all users can experience higher quality mobile service.

For you, this means Wi-Fi calling can help you have better mobile network quality, and it can help you save money on your mobile service bill, especially if you pay for a limited number of minutes on your mobile plan.

Calls made over a Wi-Fi network are usually free when made within the U.S. or from international locations to the U.S.

Wi-Fi calls from the U.S. to other countries may incur charges, depending on the guidelines established by your mobile carrier.

When you think of Wi-Fi calling, services like Skype or Zoom might come to mind, and they are services that work similarly to Wi-Fi calling.

The big difference is that Wi-Fi calling is a feature on your smartphone that, once enabled, requires little additional input from you. Whether you’reallowing Wi-Fi calling for an iPhone , turning it onfor an Android phone , or trying toenable it on a Samsung phone , the instructions are all generally the same.

To enable Wi-Fi calling, all you need to do is go to yourCellular settings on iPhone orMobile Network on Android and toggle Wi-Fi calling on. That’s all.

All smartphones are different, and you may have an iPhone or an Android phone that doesn’t have these same options. Generally, you’re looking for a Settings option directly related to your cellular network, mobile network, or network connections. Once you find that, the setting to enable (or disable) Wi-Fi calling should be easy to locate.

After that, when you’re within range, your calls will go through a Wi-Fi network. When you’re outside the area of a Wi-Fi network, your calls go through your service carrier’s network, and it’s unlikely that you’ll ever notice the difference.
