The ability to make and receive telephone calls over a Wi-Fi network, rather than a cellular network, is a feature offered on many Android devices. This functionality leverages Voice over Internet Protocol (VoIP) technology to transmit voice data through a Wi-Fi connection. The process involves the Android operating system establishing a secure connection with the mobile carrier’s servers via the internet. Once authenticated, the device can place and receive calls using the internet connection as if it were connected to the cellular network. The user’s phone number remains the identifier for these calls.
This capability is particularly beneficial in areas with weak or non-existent cellular coverage but reliable Wi-Fi. It can also reduce reliance on cellular data plans and potentially lower calling costs, especially when traveling internationally. The introduction of this technology represents a significant advancement in mobile communication, offering users increased flexibility and improved call quality in various environments. Its integration reflects an evolving landscape where internet connectivity complements and, in some cases, replaces traditional cellular infrastructure.
