Wifi-Calling: What is it? How Does it Work?


In today’s digital era, staying connected is more important than ever. Whether you’re at home, in the office, or on the go, having a reliable and seamless means of communication is crucial. 

This is where Wifi-calling comes in. But what exactly is wifi-calling and how does it work? In this article, we will delve into the world of wifi-calling, exploring its features, benefits, and the technology behind it.


What is Wifi-Calling?

Wifi-calling, also known as voice over wifi (VoWifi), is a technology that allows users to make and receive phone calls using a wireless internet connection rather than traditional cellular networks. With wifi-calling, you can use your smartphone to make calls even in areas with weak or no cellular coverage. It basically uses your existing wifi network to transmit voice calls.

How Does Wifi-Calling Work?

Wifi-calling works by utilizing the internet connection available on your smartphone. When you make a call, your device converts your voice into digital data packets. These packets are then transmitted over the internet to the wifi-calling servers provided by your service provider.

Once the data packets reach the destination, the servers convert them back into audio signals and send them to the recipient’s device. This process allows you to make and receive calls seamlessly, as if you were using a regular cellular network.

Benefits of Wifi-Calling

Enhanced Call Quality: Wifi-calling often provides better call quality compared to traditional cellular networks, especially in areas with poor signal strength. This is because voice data is transmitted over the internet, which usually offers a more stable and reliable connection.

Expanded Coverage: With wifi-calling, you can make calls from any location with an internet connection, even if there is no cellular coverage available. This can be particularly useful when traveling abroad or in remote areas with limited network coverage.

Cost Savings: Wifi-calling allows you to make calls without consuming your cellular plan’s minutes. Instead, the calls are routed through the internet, which can save you money, especially on international calls.

Seamless Transition: Wifi-calling seamlessly transitions between wifi networks and cellular networks as you move from one location to another. This means that your calls remain uninterrupted even if you switch between wifi and cellular networks.

Multi-Device Integration: Wifi-calling can be easily integrated with other devices, such as tablets and smartwatches. This enables you to make and receive calls using these devices, as long as they are connected to the same wifi network as your smartphone.

Setting Up Wifi-Calling

To use wifi-calling, you need to ensure that your smartphone and service provider support this feature. Most modern smartphones have built-in wifi-calling capabilities, but it’s always a good idea to check with your device manufacturer to confirm compatibility.

To set up wifi-calling on your smartphone, follow these general steps:

  • Go to your device’s settings and navigate to the “Wifi Calling” or “Connections” section.

  • Enable the wifi-calling feature and follow any on-screen prompts to complete the setup process.

  • Verify your mobile number and address for emergency services purposes.

Once set up, you will be able to make and receive calls using wifi-calling whenever you are connected to a wifi network.

It is worth noting that while wifi-calling provides many benefits, it relies on a stable and secure internet connection. The quality of your wifi network will directly affect call quality and reliability.


Wifi-calling has revolutionized the way we stay connected by allowing us to make and receive calls using a wifi network. Its convenience, expanded coverage, and cost-saving features make it an attractive option for many smartphone users. 

By understanding how wifi-calling works and setting it up on your device, you can enjoy seamless communication wherever you are. So, next time you find yourself in an area with weak cellular coverage, remember to switch to wifi-calling and stay connected without any interruptions.
