How about VoIP? Very useful. Tell me ~ ~

The call quality of VoIP is one of users' favorite choices. If the call quality of VoIP is not good, or the conversation between the two sides is ambiguous, or sentences are lost, then no one will use cheap VoIP. I'm using KC VoIP now, and it's generally good. No matter before or after sale, there is basically no difference, and the call effect is just as good. This VoIP phone can be used on both computers and mobile phones. Even if it is inconvenient to use the computer, you can use your mobile phone to surf the Internet, send text messages or download mobile phone software. You can make a phone call anytime, anywhere, and the phone bill is super cheap, ranging from 3 cents for a computer to 6 cents for a mobile phone.
