A free app for Android, by Callyo.

VIP is the solution to a problem that has plagued the telecom industry for decades: how to provide seamless connections for mobile services to customers. In today’s world, where more and more people are connecting to the Internet, it is becoming increasingly difficult to make and maintain a connection that is fast, reliable, and secure. The solution to this problem is VIP, an application that allows you to make and manage calls using your mobile device, and the VIP line, a virtual number that you can use on your mobile devices to make and receive calls.

How does VIP work?

When you make a call using the VIP app, you will be connected to the other party via a connection that is fast, reliable, and secure. You will not be charged for the call, and you will not be subject to any fees.
