A software application designed for devices operating on the Android platform that enables voice calls over a wireless internet connection, rather than the cellular network traditionally used. For example, if a cellular signal is weak but a Wi-Fi network is available, an individual can still place and receive calls utilizing the app.
This technology is significant because it extends call functionality to areas with poor cellular coverage, enhancing communication reliability. Historically, such capabilities were limited to cellular networks, but the rise of ubiquitous Wi-Fi access has broadened access to reliable voice communication, particularly for users in rural or densely populated areas where cellular signal strength may be compromised.
