Viber is a text messaging and phone app that lets you use a wifi connection or your phone's 3G/4G connection to communicate with others. If the person you are calling or texting has Viber, the phone calls and texts are free. You can also send text messages and keep in touch without a phone connection, which is especially helpful when traveling abroad. All you need is a wifi connection.
"Viber works on most Android, iPhone, Blackberry, Windows Phone, Nokia and Bada devices. Viber is also available for Mac and Windows." Read more about Viber here.
