WhatsApp introduced free calling between it's users a while ago and has been rumored to introduce video calling in near future. WeChat a competing China based instant messaging service has now introduced a new feature which will appeal to many, - a cheap VOIP calling feature allowing users to call domestic and international phone calls to cellphones and landliness across the globe.

Named WeChat Out, the feature is similar to Skype Out and Viber Out. WeChat is claiming their service to be cheaper with better call quality then the competition. WeChat is also offering a free trial credit of $0.99, which is enough for upto 100 minutes of international calls.

WhatsApp enabled and tested their Voice calling feature to a limited number of users initially and later rolled out to all users and other operating-systems. Leaked screenshots by an German site MacerKopf suggest that popular messaging service is all set to launch video calling feature for it's users.

WhatsApp has over 900M+ users which it acquired in a short span of just 6 years, the free video calling feature on this popular IM service is surely going to give competition substantial jitters of the likes of Apple (FaceTime), Microsoft (Skype), Google (Hangouts) and mobile-carriers.

The much awaited WhatsApp Calling feature already made it's way to Android OS and there are tricks to get a glimpse of the feature if you have an rooted android phone. The feature which has already been officially confirmed to CNET by WhatsApp spokesperson and now a selected few Apple iOS users have started getting WhatsApp Calling feature activated on their devices, the images and videos of the same are as shared below. Do mind that the Apple iOS WhatsApp version shown in the app is 2.11.17 which is most probably a beta version as the latest version listed on iTunes Store is v 2.11.16.

Also, beware of the fake WhatsApp messages circulating which claims to activate the calling feature asking users to invite others to get it. The said message asks you to complete a survey after using your help to spread to 10 other numbers and will eventually install malware on the phone. Stay clear of this scam.
