Messenger Viber is actively used by people from around the world both on the computer and on the phone. In it, you instantly can exchange voice and text messages, photos and video files.
Change one Viber user to another you can without deleting the application. You just have to run out of the current account and go under a different number.
Removing correspondence in the messenger is fraught with loss of important information. If you erased the messages by chance or were forced to do it, and now it needed to return the data back, then you should not despair, because such methods exist.
Holders of devices such as a smartphone or computer, probably know about the Viber application. Only the availability of Internet connections and a mobile client will give the opportunity to communicate with any subscriber of the network.
