What is Wi-Fi calling, its benefits and how to activate it on your phone – Technology News, Firstpost



In recent years we have seen the quality of mobile networks go downhill. As a result, we must have experienced calls being dropped frequently, and in most cases the quality of the voice calls is patchy at best. This is where Wi-Fi calling comes into play.

To put it very simply, instead of using LTE or 4G data to amplify the signals over which voice calls work, Wi-Fi calling is a system where your phone uses the Wi-Fi networks around it. The way it works is that calling works by sending the same cellular data packets as Wi-Fi VoIP over a Wi-Fi connection and over the Internet.

The end result is that we get a much better and more durable connection that also significantly improves the quality of the connection.

What is WiFi calling and how does it work?

Wi-Fi calling is a feature that allows users to make calls and send text messages over a Wi-Fi network instead of your telecom provider’s network. Basically, your phone sends data packets with voice over Wi-Fi and then over the Internet to the person on the other end of the line. Your device must support Wi-Fi calling, which is usually true for most devices manufactured after 2017.

Does it use more power and data?

Calling over WiFi is actually much more energy efficient in the bigger picture. As a private individual, you will lose about 4-5 MB for a 5-minute conversation. As for power consumption, this is usually less than what a normal call would consume, especially if you’re in an area with patchy telecom coverage.

In addition, mobile data relies on cell towers, which can be expensive to install and much more expensive to maintain. Calling via WiFi goes through telecom internet cables, so there is little energy wasted.

What does calling via WiFi cost?

Calling via WiFi costs you nothing. It is a free service and users do not have to pay anything extra to use it. All they need to do is make sure that their device supports the feature and that their service provider has activated the feature on their end.

What are the advantages of calling via WiFi?

Calling via WiFi has several advantages. First, the call quality is noticeably better in most cases. Second, it is very effective in densely populated areas where cell coverage can be weak, for example in high-rise apartments. Third, you don’t have to pay extra to get better quality services. And finally, if you only use Wi-Fi calling and avoid cell calls, you may be able to get more screen time from your cell phone.

There are a few drawbacks to using Wi-Fi calling that one should keep in mind. It may be a little slower to connect, but once connected the signal strength is off the charts. Currently, service providers do not allow users to make international calls using Wi-Fi calling. Also in sparsely populated areas calling via WiFi does not work well.

How to activate WiFi calling?

You don’t really need to do anything to activate Wi-Fi calling, your service provider will activate it as long as your device supports the feature.

How do I check if my service provider has activated Wi-Fi calling?

If you are using an Android phone, go to Settings > Mobile networks or connections > Wi-Fi and see if Wi-Fi calling is visible or not. Or, if you are connected to Wi-Fi and on a call, you should be able to see the Wi-Fi symbol in the dialer screen.

If you’re using an iPhone, go to Settings > Phone > Cellular Data > Wi-Fi Calling. The option only appears if your carrier supports Wi-Fi calling.
