What is WiFi Calling?
WiFi calling is a feature that allows you to make phone calls using a WiFi network instead of a traditional cellular network. This technology uses Voice over Internet Protocol (VoIP) to transmit your voice calls over the internet. WiFi calling is also known as VoWiFi or WiFi-based calling. It’s a convenient way to make calls when you’re in an area with a weak cellular signal or when you’re roaming internationally.
WiFi calling works by using your phone’s WiFi capabilities to connect to a nearby WiFi network. Once connected, your phone switches from using the cellular network to using the WiFi network to make and receive calls. This allows you to make calls even when you don’t have a strong cellular signal. Many phones, including iPhones and Android devices, support WiFi calling, and most carriers offer this feature to their customers.
How Does WiFi Calling Work?
WiFi calling works by using a combination of technologies to enable voice calls over the internet. When you make a call, your phone first connects to a nearby WiFi network. Then, it uses the internet to transmit your voice to the recipient’s phone. This transmission happens in real-time, allowing for a seamless conversation. The recipient’s phone can be connected to a cellular network or another WiFi network, and the call will still be connected.
The call quality depends on the strength and speed of your WiFi connection. If you have a strong and stable WiFi connection, your call quality will be clear and uninterrupted. However, if your WiFi connection is weak or slow, you may experience dropped calls, poor audio quality, or delays. Additionally, some carriers may have specific requirements or restrictions for using WiFi calling, so it’s essential to check with your carrier to see if WiFi calling is available and what the requirements are.
