Applications enabling voice calls and text messaging over a Wi-Fi network on Android operating systems are designed to bypass traditional cellular networks. These applications leverage Voice over Internet Protocol (VoIP) technology to transmit communication data via a Wi-Fi connection instead of a mobile carrier’s infrastructure. A user with an Android smartphone connected to a Wi-Fi network can utilize one of these applications to make calls even in areas with poor cellular coverage.
The significance of these applications lies in their ability to improve connectivity in areas with limited cellular signal strength. They can reduce reliance on cellular data plans, potentially lowering communication costs, especially when calling internationally. Historically, such applications have emerged as a response to the need for consistent and affordable communication alternatives, particularly in areas with unreliable cellular infrastructure or for individuals seeking to minimize cellular usage.
