A mobile application utilizing a wireless internet connection to facilitate phone calls on Android devices, bypassing the traditional cellular network, offers a cost-effective alternative for communication. For example, an individual traveling internationally can use such an application to make calls to their home country without incurring roaming charges, provided a stable WiFi network is available.
The availability of these applications is significant because it expands communication possibilities in areas with limited cellular coverage but reliable internet access. Their history traces back to the increasing ubiquity of WiFi and the demand for cheaper calling solutions. These applications address the need for accessibility, affordability, and convenience in modern communication.
