Key Takeways:

Wi-Fi Calling lets you make and receive regular phone calls over a Wi-Fi connection when mobile network coverage is weak.
It works through your mobile carrier and uses your existing mobile number.
You need a compatible smartphone, a supported mobile network, and a stable Wi-Fi connection.
Wi-Fi Calling is particularly useful indoors, where cellular signals may be weak.
A reliable fibre broadband connection can help provide a stable network for Wi-Fi Calling at home.

What Is Wi-Fi Calling?

Wondering what is WiFi calling and how it differs from a regular mobile call? Wi-Fi Calling, also known as Voice over Wi-Fi (VoWi-Fi), is a feature that lets you make and receive calls using a Wi-Fi network instead of relying entirely on a cellular signal.

Normally, your phone connects to a nearby mobile tower when you make a call. With Wi-Fi Calling enabled, your smartphone can use an available Wi-Fi connection to transmit the call when cellular reception is weak or unavailable.

Wi-Fi Calling continues to use your regular mobile number and the phone's built-in dialler. You don't need to open a separate app or call another person through a platform such as WhatsApp.

This makes Wi-Fi Calling useful in places such as homes, offices, basements, or other indoor areas where mobile signals may not be strong enough for reliable calling.

It is important to note that Wi-Fi Calling is different from internet-based calling apps. Apps such as WhatsApp, Google Meet, and Skype use their own platforms to make calls, while Wi-Fi Calling is integrated with your mobile carrier's network.

How Does Wi-Fi Calling Work?

If you're wondering how Wi-Fi calling works, the basic process is quite straightforward.

When you speak during a Wi-Fi call, your smartphone converts your voice into digital data. This data travels through the connected Wi-Fi network and reaches your mobile carrier's network through the internet. The carrier then routes the call to the recipient.

The process generally works as follows:

Your smartphone connects to a Wi-Fi network.
Wi-Fi Calling is enabled on your device.
Your voice is converted into digital data.
The data travels through the Wi-Fi connection.
Your mobile carrier's network processes and routes the call.
The recipient receives the call through their phone.

The entire process happens quickly, so you can make and receive calls almost like you would through a conventional cellular connection.

The quality of the call depends on the stability of your Wi-Fi connection. A reliable connection can provide a better experience, while an unstable network can cause delays, interruptions, or dropped calls.

Step-by-Step Guide on How to Make Wi-Fi Calls

If you want to know how to use Wi-Fi Calling, start by checking whether your smartphone and mobile carrier support the feature. The exact settings can differ depending on your device, operating system, and network provider.

Step 1: Check Device and Carrier Compatibility

First, confirm that your smartphone supports Wi-Fi Calling and that your mobile carrier provides the service for your plan.

Not every device, mobile network, or plan necessarily supports the feature.

Step 2: Connect Your Phone to Wi-Fi

Connect your smartphone to a reliable Wi-Fi network. A stable connection is important because the call will use Wi-Fi to transmit voice data.

Avoid using a network that frequently disconnects or has very weak signal strength.

Step 3: Activate Wi-Fi Calling

Once compatibility is confirmed, you can activate Wi-Fi Calling through your smartphone's settings.

Depending on the device, you may find the option under:

Connections
Mobile Network
SIM settings
Network & Internet

Turn on the Wi-Fi Calling option and follow any instructions displayed on the screen.

Step 4: Make a Regular Phone Call

Once Wi-Fi Calling is enabled, use your phone's standard dialler to call someone. If the feature is supported and your phone is connected to a suitable Wi-Fi network, the call can be routed through Wi-Fi.

You generally don't need to change how you dial or use a separate application.

Step 5: Maintain a Stable Wi-Fi Connection

Keep your smartphone connected to a stable Wi-Fi network during the call. If the connection becomes weak or drops, the call quality may be affected.

Depending on your device and carrier, the phone may switch between Wi-Fi and the cellular network when possible.

Benefits of Wi-Fi Calling

The benefits of Wi-Fi Calling are particularly noticeable in places where cellular coverage is inconsistent. It can provide an alternative connection for regular phone calls without requiring a separate calling app.

Benefit	How It Helps
Useful in weak-signal areas	Allows calls over Wi-Fi when cellular reception indoors is poor.
Better indoor connectivity	Helps you stay connected in buildings, basements, and other areas where mobile signals may struggle.
Uses your existing number	You can make and receive calls through your regular mobile number.
No separate calling app	Calls can be made through the phone’s standard dialler.
Convenient at home	Your home Wi-Fi can provide an alternative connection when mobile reception is weak.
Works across supported devices	Compatible smartphones can use the feature once it is enabled and supported by the carrier.

Is Wi-Fi Calling Good?

So, is Wi-Fi Calling good for everyday use? It can be particularly useful if your home or workplace has weak mobile reception but a reliable Wi-Fi connection.

However, Wi-Fi Calling isn't a replacement for a stable internet connection. If your Wi-Fi is slow, congested, or frequently disconnects, the quality of your calls can also be affected.

How to Enable Wi-Fi Calling on Android

Enabling Wi-Fi Calling on Android is generally straightforward, although the exact steps can vary between smartphone manufacturers and Android versions.

Follow these steps:

Open Settings on your Android smartphone.
Go to Connections, Mobile Network, or Network & Internet.
Select your mobile SIM or network.
Look for Wi-Fi Calling.
Turn on the Wi-Fi Calling option.
Connect to a stable Wi-Fi network and make a test call.

If you cannot find the Wi-Fi Calling option, your smartphone, mobile carrier, or current plan may not support the feature. In that case, check with your network provider.

How to Enable Wi-Fi Calling on iPhone

The steps for enabling Wi-Fi Calling on an iPhone are also simple, although the exact menu names may vary with the iOS version.

Open Settings.
Select Mobile Service or Cellular.
Choose your mobile number or SIM.
Tap Wi-Fi Calling.
Turn on Wi-Fi Calling on This iPhone.
Follow any instructions that appear on the screen.

Wi-Fi Calling availability depends on your mobile carrier, plan, and device compatibility.

Why a Reliable Wi-Fi Connection Matters for Wi-Fi Calling

Wi-Fi Calling depends on the quality of your internet connection. A weak or unstable Wi-Fi network can affect voice quality, create delays, or interrupt a call.

A reliable fibre broadband connection can provide the stable connectivity required for everyday activities such as Wi-Fi Calling, video calls, streaming, online learning, and working from home.

Tata Play Fiber uses a 100% Fiber-to-the-Home (FTTH) network, providing a direct fibre connection to your home. A stable broadband connection can help you make better use of Wi-Fi Calling, particularly in rooms or areas where cellular reception is weak.

Conclusion: Enhancing Communication with Wi-Fi Calling

Wi-Fi Calling gives you another way to make and receive regular phone calls when cellular coverage is weak. It works through your Wi-Fi connection while continuing to use your mobile number and carrier service.

To use it, you need a compatible smartphone, a supported mobile carrier, and a stable Wi-Fi connection. If you frequently experience poor mobile reception at home, combining Wi-Fi Calling with a reliable fibre broadband connection can help you stay better connected.
