What is WiFi Calling: A Comprehensive Guide to Making Calls Over WiFi


WiFi calling has revolutionized the way we communicate, allowing us to make phone calls using a WiFi network instead of relying solely on cellular networks. In this comprehensive guide, we will explore what WiFi calling is, how it works, and its benefits.

What is WiFi Calling?

WiFi calling is a feature that enables users to make and receive phone calls over a wireless internet connection instead of using cellular networks. It utilizes Voice over Internet Protocol (VoIP) technology to transmit voice data over a WiFi network.

How Does WiFi Calling Work?

To use WiFi calling, you need a compatible device (smartphone, tablet, or computer), a WiFi network, and an active wireless service plan with WiFi calling support. When you make a call, your device connects to the WiFi network, and the call is routed through the internet to the recipient. The recipient does not require WiFi calling capability to receive the call.

Benefits of WiFi Calling

1. Expanded Coverage: WiFi calling enables users to make and receive calls even in areas with poor cellular coverage. As long as there is an available WiFi network, you can stay connected.

2. Cost Savings: WiFi calling allows you to make calls without using cellular minutes, which can save you money, especially when making international calls.

3. Better Call Quality: Since WiFi connections are typically faster and more stable than cellular networks, WiFi calling often offers better call quality with reduced background noise and dropped calls.

4. No Additional Apps Required: Unlike other VoIP services, WiFi calling does not require the use of third-party apps. It is integrated into your device’s native calling features, making it easy to use and accessible.

Setting Up WiFi Calling

1. Check Device Compatibility: Ensure that your device supports WiFi calling by consulting the manufacturer’s specifications or contacting your wireless service provider.

2. Enable WiFi Calling: Go to your device’s settings, locate the WiFi calling option, and enable it. You may need to enter your emergency address for emergency services.

3. Connect to WiFi Networks: Make sure you are connected to a stable WiFi network. WiFi calling will automatically activate when a WiFi network is available and selected.

Limitations of WiFi Calling

While WiFi calling offers numerous benefits, it also has its limitations:

1. Internet Connection Required: As WiFi calling relies on a wireless internet connection, it cannot be used in areas with no WiFi access.

2. Battery Consumption: Using WiFi calling may drain your device’s battery faster than regular cellular calls, especially if the WiFi signal is weak.

3. Emergency Calls: WiFi calling may not support emergency services in all locations. It is essential to provide your emergency address when setting up WiFi calling to ensure accurate emergency assistance.

4. Call Handover: If you move out of the WiFi range during an ongoing WiFi call, the call may drop as the device tries to switch to the cellular network.


WiFi calling is a valuable feature that allows us to make calls over a WiFi network, providing expanded coverage, cost savings, and improved call quality. By following the simple setup process, users can enjoy the benefits of WiFi calling on their compatible devices. However, it is crucial to be aware of its limitations and ensure a stable internet connection for optimal performance. Stay connected with WiFi calling and enjoy seamless communication wherever you go.
