VoWiFi is a lifesaver for those who stay on highrise buildings or where connectivity is poor indoors. So, what is it? let us find out!

What is WiFi Calling?

Well, the answer should be quite obvious. WiFi calling is a calling facility that would require no option for cellular networks. If you have access to a WiFi network in the region you are currently in, you should be able to make a call to your number. The WiFi calling works efficiently with both landlines and mobile numbers alike.

If a phone supports WiFi calling, it does not need you to access individual apps or other services. You would be able to call or text any of the numbers – including overseas numbers – as long as you have a working WiFi network. Since the calling functionality does not work with the cellular network but relies upon the WiFi connectivity, it is called WiFi.

The service will work with T-Mobile, Sprint, and Verizon, and all these significant carriers support WiFi calling.

How is WiFi calling beneficial for your needs?

Well, there is a considerable number of services and free WiFi connectivity options available. The number of free WiFi access points has been quite efficient, and you would find that the WiFi points are set to go up by the year 2021. The number of WiFi hotspots is expected to go up to about 250 million soon.

The faster connectivity would be a good idea for use with the WiFi connection. However, one of the difficult tasks would be you would find that there would be one or two seconds of delay during the conversation. That would be a little annoying for you.

Yet another excellent option that it would offer you would be a saving in terms of battery. A weak cellular coverage can result in severe issues and can drain your battery faster. Using WiFi calling in such situations can prove to be a battery saver in more ways than one.

How much would the WiFi calling cost? The WiFi calling should not cost much. Most of the carriers would treat your WiFi calls as regular calls themselves. The call charges would apply to the WiFi calls even when making a call using WiFi or a cellular network. If you are a frequent overseas traveler, the roaming or international call charges will not apply to you. This can be the perfect option for use with WiFi calling.

Equipped with that knowledge, here are a few pros and cons that the WiFi calling feature comes with.


  • You do not need any specialized apps or third-party dialers for the sake of connectivity. You can use the same dialer that you use with the cellular calls.
  • The calls made to the US would be free. These calls would be open even when you call from an overseas country.
  • You would be able to make video calls if your phone supports such a feature.


  • WiFi calling functionality will work with only those devices which support HD voice technology. If you are using other phones with no support for HD Voice quality or 4G connectivity, you would not be able to use WiFi calling.
  • Not every operator may support WiFi calling feature. Many Android devices may not support WiFi calling.
  • Calls made to non-US numbers may or may not be free. You may need to check out the features.

WiFi calling has been around for a long. Multiple third-party options offer you WiFi calling functionality. Some unique concepts would include Skype, WhatsApp, and Facebook Messenger. However, this is in sharp contrast to the WiFi calling feature offered by smartphones and carriers, which provide you access to the built-in WiFi connectivity. You do not need to be reliant on any of the third-party options for the purposes.

If you are unsure whether your service provider supports WiFi calling or not, you can check their official website to check if the connectivity option is supported.

Switch to a router that supports 802.11n or 802.11ac. Once you do that, everything should be back to work, and you should have access to WiFi calling functionality.

You would find that you are connected to the WiFi connectivity through a WiFi calling icon on your device. As soon as you move out of the area where the WiFi coverage is available, you would find that the call switches to the cellular network, if possible. However, you may need to check it with your service provider.
