What is WiFi Calling and How Does it Work?
WiFi Calling is a technology that allows users to make voice calls and send text messages over a WiFi network instead of using their cellular network. This technology uses Voice over Internet Protocol (VoIP) to transmit voice and data packets over the internet, enabling users to communicate even when their cellular signal is weak or unavailable. WiFi Calling is often used in areas with poor cellular coverage, such as rural areas, basements, or buildings with thick walls.
WiFi Calling works by connecting your phone to a WiFi network, which then connects to the internet. When you make a call or send a text message, your phone converts your voice or message into digital data and sends it over the WiFi network to the recipient’s phone. The recipient’s phone then converts the digital data back into voice or text, allowing them to receive your call or message. This process happens in real-time, allowing for seamless communication.
Does WiFi Calling Work When Service is Bad?
WiFi Calling can work even when your cellular service is bad, but it requires a stable and strong WiFi connection. If your WiFi connection is weak or unstable, your WiFi Calling service may not work properly, and you may experience dropped calls, poor voice quality, or delayed text messages. However, if you have a strong and reliable WiFi connection, WiFi Calling can provide a more stable and reliable communication service than your cellular network.
It’s essential to note that WiFi Calling is not a substitute for your cellular network, and it’s not always available. Some carriers may not support WiFi Calling, and even if they do, it may not be available in all areas or on all devices. Additionally, WiFi Calling may not work during power outages or when your internet service is down.
