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.

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.

Just days after WhatsApp introduced the much needed Desktop/Web access for the world's leading instant messenger service, we now have WhatsApp Call feature making it's appearance on some selective installations. It seems the WhatsApp Voice Call feature will be invite only for now where a user who already has the feature can initiate a call to a new user activating it on the other users installation. A semi-functional trick to activate the WhatsApp Call feature before everybody else is shared below.

Google Voice has been a great way to make and receive free calls to USA and Canada. We have also shared a trick which enables users to make free calls to 60+ countries using their Google Voice account. Now, Google has announced the ability to make voice calls to regular landlines and mobiles from Gmail via Google+ Hangout, and to sweeten the deal calls to the US and Canada are now free from all countries where Hangouts calling is available. So this means if you have any relative or friend in USA or Canada you can call them for free from anywhere in the world.

This is not all, the new “Hangouts calling” also supports conference calling to multiple phone numbers and video participants on the same call, as well as play sound effects with the Google Effect app like applause or laughter.
