What is Wi-Fi Calling?

Wi-Fi calling, also known as Voice over Wi-Fi (VoWiFi), is a technology that allows you to make and receive phone calls over a Wi-Fi network instead of using your cellular network. It provides a convenient way to stay connected when you have limited or no cellular coverage, especially in areas with weak signal strength.

How Does Wi-Fi Calling Work?

Wi-Fi calling works by utilizing your internet connection to transmit phone calls as data packets instead of traditional cellular signals. When you make a call, the voice data is converted into digital packets, which are sent over the internet to the recipient’s device. The recipient device then converts the packets back into voice data, allowing for seamless communication.

Benefits of Wi-Fi Calling

1. Enhanced Coverage: Wi-Fi calling eliminates the restrictions of cellular signal strength, allowing you to make and receive calls in areas with weak or no cellular coverage. As long as you have a stable Wi-Fi connection, you can use Wi-Fi calling to stay connected.

2. Cost Savings: Wi-Fi calling can be cost-effective, especially when making international calls. Instead of paying expensive roaming charges or international rates, you can make calls using your Wi-Fi network, saving money on long-distance calls.

3. Better Call Quality: Wi-Fi calling typically offers better call quality compared to traditional cellular calls. As the voice data is transmitted over a reliable internet connection, there is often reduced background noise and increased voice clarity.

4. Seamless Handover: Wi-Fi calling allows for seamless handover between Wi-Fi and cellular networks. If you are on a call using Wi-Fi and move out of Wi-Fi coverage, the call can automatically transition to your cellular network without dropping.

Setting Up Wi-Fi Calling

In order to use Wi-Fi calling, your device needs to support the feature and be connected to a Wi-Fi network. Here’s a general guide to setting up Wi-Fi calling:

  1. Check Compatibility: Verify if your device and carrier support Wi-Fi calling. Most modern smartphones and carriers offer this feature, but it’s always best to double-check.
  2. Enable Wi-Fi Calling: Go to your device’s settings and find the Wi-Fi calling option. Toggle it on and follow any prompts or instructions provided by your carrier.
  3. Configure Emergency Address: Some carriers require you to provide a registered emergency address for Wi-Fi calling. This ensures that emergency services can locate you in case of an emergency.
  4. Test the Feature: Once set up, make a test call using Wi-Fi calling to ensure it’s functioning properly. You can simply dial a number as you would with regular calls.

Limitations of Wi-Fi Calling

While Wi-Fi calling offers numerous benefits, there are certain limitations to be aware of:

1. Reliant on Wi-Fi Network: Wi-Fi calling requires a stable Wi-Fi connection to function properly. If you’re in an area with no Wi-Fi coverage, you won’t be able to utilize this feature.

2. Battery Drain: Making calls over Wi-Fi may consume more battery power than regular cellular calls. It’s advisable to keep your device connected to a power source while using Wi-Fi calling for extended periods.

3. Limited Carrier Support: Not all carriers support Wi-Fi calling, and some may restrict the feature to specific device models or plans. Check with your carrier to ensure compatibility.

4. Call Quality Issues: While Wi-Fi calling generally provides better call quality, it can occasionally be affected by network congestion or poor Wi-Fi signal strength, resulting in dropped calls or reduced audio quality.


Wi-Fi Calling is a technology that allows you to make and receive phone calls using a Wi-Fi network rather than relying solely on cellular coverage. It offers enhanced coverage, cost savings, better call quality, and seamless handover between Wi-Fi and cellular networks. By setting up Wi-Fi calling on your compatible device, you can enjoy these benefits and stay connected even in areas with weak or no cellular signal. However, it’s important to be aware of the limitations and ensure a stable Wi-Fi connection for optimal performance.
