Who says you can't make free calls? Can't send text messages for free? These have all become clouds since Viber appeared. Viber is a free network communication software that is extremely popular recently, and some people in the network evaluate it as better than Skype. Viber supports not only iPhone, but also iPodTouch/iPad applications, as long as you have a pair of headphones with a microphone. It doesn't need to register an ID like Skype, and the mobile phone number is your ID number, which is very simple. At present, Viber supports multiple languages, including Chinese. 1, open Viber, click "Continue" without saying anything, and proceed to the next step. 2.

A window will pop up to the effect that "Viber needs to access your address book", and Viber will find out whether anyone has used Viber service from your contacts, so as to recommend it to you without inviting your friends to use Viber again. Directly recommend "OK". 5. Enter the mobile phone number, wait a few seconds, and you will receive a four-digit verification code. 6. Then go to the next step and directly input the obtained authentication code. In case you don't receive the verification code, please click "No Code" at the top right of the screen, and the screen will automatically jump to Viber's page, and click "Get Code" at the bottom of the screen. After a few seconds, you will receive a phone call that says "Unknown phone number". Don't worry, it's from Viber's customer service and will inform you of Viber's code in English.

To sum up, as a free network communication software, the operation provided by Viber is much simpler than Skype, and you don't need to register. And when you use it for the first time, there will be clear process tips, and you can get everything done as long as you know a little English. The most important thing is the call quality. In my actual experience, I found that Viber's call quality is not worse than ordinary calls, and there is no call barrier. One more thing, unlike other network calling software, Viber only supports iPhone, and it also supports iPodTouch/iPad. As long as you have a WIFI wireless network, you can call any friend with the above equipment, and you don't have to worry about the cost, even if it is an international long distance! There is also a small problem in practical use, that is, sometimes the waiting time will be too long when receiving the authentication code. I suggest you try more times.
