MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Wi-Fi calling works through transmitting the same cellular data packets as Wi-Fi VoIP through a Wi-Fi connection and across the internet. From the internet, data is passed to the cellular network and then back to the answering party. Wi-Fi calling must be supported by the smartphone to work.
