• Make calls using the built-in Wi-Fi calling feature of your phone.

• No additional applications are required to configure Wi-Fi calling.

• To provide clear voice, calls, and text messages, the system relies on VoIP technology.

When you dial, your voice is converted into digital packets sent via Wi-Fi through your mobile network. The packets convert back to sound on the other end, ensuring better call quality. It’s ideal for places with poor cellular signal or limited traditional cellular access.

The benefit of Wi-Fi calling is simple—it works indoors, supports travel, & saves money on international calling without using much cellular data. Though there are cons of Wi-Fi calling, like relying on public Wi-Fi, it still offers reliable calling security & steady performance for both personal use and call centers.

Now that you understand what Wi-Fi calling is and how it differs from traditional cellular communication. Let’s explore how this technology actually functions behind the scenes.

How Does Wi-Fi Calling Work?

Wi-Fi calling is a variant of voice calls and text messaging that uses VoIP technology to transmit calls and messages via a Wi-Fi network instead of a cellular network. It implies that you will be able to make and accept calls even in areas where your cell signal is weak, provided that your Wi-Fi is good.

Here’s how the process works:

1. Enabling the Feature

First of all, you should have Wi-Fi calling active in the settings of your phone. After it is switched on, your phone automatically recognizes when the cell phone network is in a poor condition. It then gives priority to Wi-Fi signals in making calls and texts.

Any manual changes are not needed because all these activities take place in the background.

2. Connecting to a Wi-Fi Network

Once the feature is turned on, the phone will automatically connect to any other Wi-Fi network or Wi-Fi hotspot that is within range. The call quality is dependent on the strength of this connection. Good quality and clear audio are achieved with the strong Wi-Fi connection of 1 Mbps speed.

Higher speeds, like 5 Mbps or better, significantly boost call stability, especially for outbound calls or call centers using the communication platform.

3. Converting Your Voice

VoIP technology is the technology used by your phone when you make a call to convert your voice into small digital packets. Then these packets are ready to be sent through Wi-Fi. This technology is similar to online calling applications, only that Wi-Fi calling occurs directly in your phone dialer or built-in dialer.

Also, you do not need a third-party application.
