Before we dive into the differences, let’s start with the basics. Both Wi-Fi calling and cellular calling enable voice and data communication over wireless networks. However, they operate on different frequencies and infrastructure.
Celullar Calling
Cellular calling, also known as traditional calling, uses cellular networks to connect your phone to the nearest cell tower. This tower is part of a larger network of cell sites, which are maintained by your mobile service provider. When you make a call, your phone sends a signal to the nearest cell tower, which then forwards your voice data to the recipient’s phone via the cellular network.
Wi-Fi Calling
Wi-Fi calling, on the other hand, uses Wi-Fi networks to connect your phone to the internet. When you enable Wi-Fi calling on your device, you can make voice calls using a nearby Wi-Fi network. Instead of relying on cellular towers, Wi-Fi calling uses VoIP (Voice over Internet Protocol) technology to transmit your voice data over the internet.
