Recently, WhatsApp has rolled out its free voice calling feature for Android, iPhone and iOS users just like other apps including Viber and Skype which is based on VoIP technology. But no one is aware about the fact that the calling through these apps becomes more expensive when compared with regular calling, if data charges are increased.

When WhatsApp calling feature is compared with other VoIP systems including Skype, Viber, Hangouts and many more, it is estimated that all the websites consume large amount of data and thus, results in the increase of your mobile bill.

If you want to make calls via mobile phone, Viber is the best option as uses less data but if using PC or desktop go for Skype. But for VoIP voice calling feature, WhatsApp is the best among the three as you can chat, send video, images, etc without spending anything and with less data usage.

** So: Today, ZIP Management verified less data and better quality than Viber & Skype; and relatively recent article (previously posted) disclosed WhatsApp having major problems with video.

Zipt doing well indeed. Becoming more robust with improved features; streamlining and comparative advantages. Like a younger genetically gifted bodybuilder growing in time to possibly take on the 'big boys' on the global stage.
