Software applications enable cellular devices operating on the Android operating system to initiate and receive telephone calls over a Wi-Fi network. This functionality circumvents reliance on traditional cellular network coverage, utilizing a broadband internet connection as the primary pathway for voice communication. A user might employ such an application, for instance, when cellular signal strength is weak or unavailable in a specific location, such as within a building with thick walls or in a rural area.
The value of these applications lies in enhanced call reliability and potentially reduced calling costs. Individuals experiencing poor cellular service can maintain communication capabilities through available Wi-Fi networks. The widespread adoption of broadband internet access has made this technology increasingly relevant, especially in areas where cellular infrastructure is limited. Functionality for this service has evolved from third-party applications to being natively integrated into many Android devices’ operating systems.
