This as a service that allows one to make calls over the internet. Since it uses broadband, its very cheap. This technology has been around for quite some time but I don't think that alot of people have embraced it for some reason. I am not in the know about the specifics of its operation. Anyone who can shed more light on this technology?
There are lots of VoIP services available. You can have these services as mobile apps on your Android, iOS or Windows devices. I don't use VoIP service much, however, when I am using, I use as Viber, Line, What's App, Skype, and Messenger. I use Viber more than any other VoIP services.
