Viber is another very useful program for Windows Phone, thanks to which you will be able to communicate with your friends and family for free. It allows you both to chat and to share photos, videos, emoticons and other funny pictures that are present in the catalog chat, as well as to make calls. No doubt you have already thought about Skype, and in some ways you're right, but not in all.

Let's start with the fact that in this application there is no way to make video calls, and this is probably the only one its drawback when compared to Skype. Throughout the rest, the program is rather better than its competitor. The first thing we want to celebrate is an exceptional voice quality. Viber developers are not even afraid to say that the sound quality of calls through their program is much higher than the quality of conversations via GSM-communication. Having tested the program on several smartphones, we came to the conclusion that it is pure truth.

Viber's second advantage over similar products is that in order to communicate with your friends, you no longer need to fill contacts, search for friends using login, and request permission to being added. The program synchronizes with contacts in your address book, thanks to which it know who of your friends use Viber a minute after its start, and creates a separate list of people with whom you can chat for free.

The simplest registration ever

To register for a service, you just need to provide your current phone number and confirm it with a code that will come in reply. At the same time, a server of the program is searching for information on whose phones have your number in them. As soon as the information is found, all of your friends who has your number in their smartphones, will receive a notice of the fact that you also have joined the Viber service. Simultaneously, your contact list will be filled with those contacts who has your one displayed.

While using the program, you will regularly receive a notification that someone you know has connected to Viber, and it's just wonderful. Frankly speaking, before installing the program, we still had some doubts that we would find some of our friends using it. However, the first run showed that we are not alone, and almost every day we receive notice that there has become more of us. Choosing a contact, you can call as usual with GSM-communication, or make a free call over the Internet. If the called person doesn't use Viber, you can send him or her an invitation, and maybe after a while he or she will join this service.
