If you know how to enable WiFi calling, you can make voice calls over a WiFi network instead of using your cellular company's mobile network. But why would you want to do that?
Voice calls can be made using your home WiFi connection or a WiFi hotspot when you are out and about. They can be a handy calling option when you are in an area with weak or no cellular coverage, which I'm sure we have all experienced before (like on an airplane).
Typically, WiFi calls are similar to normal phone calls, using regular phone numbers. The four major wireless carriers, T-Mobile, Verizon Wireless, Sprint and AT&T, each offer their own version of WiFi calling.
WiFi call services are fairly easy to set up from your phone settings, with minor differences depending on your cell phone carrier. You'll need to check if your carrier offers WiFi calling with the phone you have. It is also important to check your wireless carrier's billing policy for WiFi calls on your service plan.

What is WiFi Calling?
This is how it works. WiFi call services allow you to make a phone call via WiFi instead of via cellular signal. To use WiFi calling, you need to find a hotspot or WiFi connection. You can go to a cafe, a library, or use a separate hotspot to make WiFi phone calls.
One great thing about WiFi calling is that it can be used while your phone is in airplane mode. In airplane mode, your phone still has access to WiFi. As a result, you can make business phone calls and send messages via your WiFi hotspot or your plane's WiFi connection.
WiFi calling has been with us for awhile, with device and phone apps like Skype, Google Hangouts, and Google Voice. Such phone apps allow users to make and receive phone calls and text messages over the internet, even if they don't have a cellular network connection.
WhatsApp is another fantastic WiFi call app, letting you make calls and send texts for free, even if you don't have a cellular coverage plan. It's available on a wide range of smartphone devices, all you need is access to a wireless network. You can even use WhatsApp on your iPod Touch or iPad.
If you have a prepaid device, you can also buy a sim card for WiFi calling. Once you buy a sim card, insert it into your phone to use it for WiFi calls and texts. Even if you don't have a prepaid device, you can download a sim VoIP app for WiFi calling.
One advantage of using your cell phone plan's WiFi service over the free WiFi calling apps is that they offer 911 emergency access, while the free Apps do not offer the ability to make emergency calls.
