In recent years we have seen the quality of cellular networks go downhill. As a result, we must have seen calls drop frequently, and in most cases voice call quality is spotty at best. This is where WiFi 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, WiFi calling is a system where your phone uses the WiFi networks around it. The way it works is by transmitting the same cellular data packets as Wi-Fi VoIP over a Wi-Fi connection and across the internet.
The end result is that we get a much better and more sustainable connection, which also greatly improves the quality of the connection.
What is WiFi Calling and how does it work?
WiFi calling is a feature that allows users to make and receive calls and SMS over a WiFi network instead of your carrier’s network. Basically, your phone sends packets of data with voice over WiFi and then over the internet to the person on the other end of the call. Your device must support WiFi calling, which is typically the case for most devices made after 2017.
Does it consume more power and data?
WiFi calling is actually much more energy efficient on the whole. As an individual you spend around 4-5 MB for a 5 minute call. Power consumption is typically lower than a regular call, especially if you are in an area with spotty telecom coverage.
Additionally, cellular data depends on cell towers, which can be much more expensive to install and maintain. WiFi calls are transmitted over telecom internet cables, so very little energy is wasted.
How much does WiFi calling cost?
WiFi calling costs you nothing. It is a free service and users don’t have to pay anything extra to use it. All they have to do is make sure their device supports the feature and their service provider has enabled the feature on their end.
What Are the Benefits of WiFi Calling?
WiFi calls have several advantages. First, the call quality is significantly better in most cases. Second, it’s very effective in densely populated areas where cellular coverage might be weak, such as in high-rise apartments. Third, you don’t have to pay extra to get better quality services. Finally, if you only use WiFi calls and avoid cellular calls, you may be able to get more screen time from your cell phone.
There are a few downsides to using WiFi calling to be aware of. The connection can be a bit slower, but once connected the signal strength is off the charts. Currently, service providers do not allow users to make international calls using WiFi Calling. Even in sparsely populated areas, WiFi calling doesn’t work well.
How do I enable WiFi Calling?
You don’t actually have to do anything to enable WiFi calling, your service provider will enable it as long as your device supports the feature.
How do I check if my service provider has enabled WiFi Calling?
If you are using an Android phone, go to Settings > Mobile Networks or Connections > Wi-Fi and then check whether Wi-Fi calls are visible or not. Or if you’re connected to WiFi and making a call, you should be able to see the WiFi icon on 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.
