What are VoIP Apps for Android?

VoIP apps utilize internet protocol to transmit voice and video calls. It allows users to communicate using their Android smartphones or tablets. These apps are an alternative to traditional telephone networks. They offer additional features, such as instant messaging, screen sharing, and video conferencing.

Here are important security risks associated with using VoIP apps on an Android device:
