After voice calls, WhatsApp is reportedly rumoured to be working on video calls. There are no officials dates or information from WhatsApp as to when the video-calling feature will go live. According to German website Macerkopf, users can opt for both the cameras for video-calls.

While the voice-calling was already announced this year, video-calling appears to be the natural next step of progression for WhatsApp.

It will be interesting to see how WhatsApp video calls perform on mobile Internet. While free WhatsApp voice calls attracted a lot of attention from users before, but soon people started to ignore it, at least in India, where it is almost impossible to have a proper conversation on even 3G networks.

In order to be successful, the video-calls will have to be optimised for slower networks, especially for regions like India where WhatsApp is one of the most popular instant messaging apps.
