Viber 15.4.0.1

With it, you can send text messages and make phone calls for free, so long as you have an Internet connection.

Thanks to Viber, you can share text messages, photographs, messages with videos or voice, locations, emoticons, and tags. In fact, within the app, you can find a sticker store where you can find new tags to buy and use in conversations.

A positive element is that besides the mobile app, it has a client for Windows and Mac. Thanks to this, you can continue your conversations on your computer, making and receiving calls no matter where you are.

Viber is a good alternative in the wide range of instant messaging apps for Android. Its audio quality during calls is pretty good by general standards.
