You've probably heard a thing or two out there about Wi-Fi calling. However, if you're not a big tech person, you may be a little confused as to what that is.

It's actually very simple: Wi-Fi calling is when you conduct a phone call over a Wi-Fi connection, rather than using your cell phone carrier's cellular network.

Here's what you should know about Wi-Fi calling, including how to set it up on your phone.

Wi-Fi calling, explained

As stated, a Wi-Fi call is a call that's placed using a Wi-Fi internet connection instead of a cell connection.

There are several advantages to Wi-Fi calling over standard voice calling. Firstly, because it uses something called a High-Definition (HD) Voice service, often calls made over Wi-Fi are clearer and easier to make out. However, this will depend on the speed of your internet connection .

If you're in an area where cellular service is spotty, Wi-Fi calls can help keep you from dropping calls.

Additionally, on most major phone carriers, Wi-Fi calling services are free, as long as the calls are being made to U.S. numbers.

You have access to Wi-Fi calling as long as you have a compatible cell phone. Don't worry that's all phones on the market today. So as long as you don't have a very old smartphone as in, older than the iPhone 6 you can use Wi-Fi calling.

You should also note that to make Wi-Fi calls, you'll also have to provide your address. This is so emergency services can reach you if you call 911.

If you want to know how to turn that capability on, here's how.
