Viber, the mobile messaging app is spreading its wings beyond voice calling on mobile after it introduced video calling to its Android and iOS apps.

The service has offered video calling from its desktop apps for some while, but Viber CEO Talmon Marco says that it is now ready to replicate the experience on mobile, after two years of work and testing. Marco says that the service is robust enough to support video calling even on the most basic network connections.

In addition, Viber 5.0 for Android and iOS introduces QR codes for sharing contact details — so if you meet someone new and want to share details, it’s as simple as scanning their code using your phone.
