Utilizing a wireless internet connection to place voice calls offers an alternative to traditional cellular networks. This method leverages Voice over Internet Protocol (VoIP) technology, enabling communication via applications or services specifically designed for this purpose. Examples include using a smartphone application connected to a home or public Wi-Fi network to dial another phone number or contact.
This communication method provides potential cost savings, especially for international calls or in areas with limited cellular coverage. Historically, it has emerged as a response to the increasing availability of widespread Wi-Fi access and the desire to bypass cellular carrier charges. This technology allows for accessibility in situations where cellular signals are weak or non-existent, enhancing connectivity.
