In this article, we’ll delve into the inner workings of WiFi calling, exploring its benefits, limitations, and what you need to know to get started.
What is WiFi Calling?
WiFi calling, also known as Voice over Internet Protocol (VoIP), is a technology that enables you to make voice calls and send texts using a WiFi network instead of a traditional cellular network. This means that as long as you have a stable internet connection, you can stay connected with friends, family, and colleagues, even in areas with poor or no cellular coverage.
How Does WiFi Calling Work?
WiFi calling works by using the internet to connect your call, rather than relying on traditional cellular towers. Here’s a step-by-step breakdown of the process:
- Your device connects to a WiFi network: When you enable WiFi calling on your device, it connects to a nearby WiFi network. This can be your home network, a public hotspot, or even a mobile hotspot.
- Your device registers with the WiFi calling service: Once connected to the WiFi network, your device registers with the WiFi calling service, which is usually provided by your carrier or a third-party app.
- You make a call or send a text: When you make a call or send a text, your device converts your voice or message into digital data and sends it over the internet to the WiFi calling service.
- The WiFi calling service connects the call: The WiFi calling service receives your digital data and connects the call to the recipient’s device, which can be a traditional phone or another device using WiFi calling.
- The call is established: Once the call is connected, you can communicate with the recipient in real-time, just like a traditional phone call.

This technology uses Voice over Internet Protocol (VoIP) to transmit voice data over the internet, allowing users to make calls from anywhere with a stable WiFi connection.
WiFi calling works by using a smartphone’s WiFi capabilities to connect to a nearby network. Once connected, the phone uses the internet connection to establish a voice call, which is then transmitted to the recipient’s phone. This technology is especially useful in areas with poor cellular coverage, as it allows users to make calls and send texts over a WiFi network.
What are the Benefits of Using WiFi Calling?
One of the main benefits of using WiFi calling is improved call quality and coverage. By using a WiFi network, users can make calls from areas with poor cellular coverage, such as basements or rural areas. Additionally, WiFi calling can provide better call quality, as it is less prone to interference and dropped calls.
Another benefit of WiFi calling is cost savings. Many carriers offer free or low-cost WiFi calling, which can be especially useful for international calls. Additionally, WiFi calling can help reduce data usage, as it uses the internet connection to make calls instead of cellular data.
What Do I Need to Use WiFi Calling?
To use WiFi calling, you will need a smartphone that supports WiFi calling technology. Most modern smartphones, including iPhones and Android devices, support WiFi calling. You will also need a stable WiFi connection, which can be provided by a home network, public hotspot, or mobile hotspot.
