In Skype, you need a user name whereas in Viber, all you need is a telephone number which can be easily taken from a global telephone dictionary- Truecaller. This is just my opinion of the two calling services. Better security/privacy compared to Viberīoth require credits which require an in app purchase or IAP which needs real money.Quality of the service be it calling or Video calling is Best and is worth the money.

New service, so should offer a refreshed UI.

Its a battle of the two international calling services- Viber Out and Skype Out. Skype is now being offered integrated to any Microsoft device like the Xbox One, Windows 8.1 running tablets, laptops and PCs (offered as a replacement to the Messaging app) and it is offered as a free download to the WP range of lineup. Skype is a Microsoft acquired software which has a main job of calling numbers internationally or locally. I know this sentence might be removed if it has to get published but everyone knows that’s the truth. Telecom companies are the real beggars of a country. It costs you a few bucks but should be cheaper compared to your ISD Rates. Anyway, Viber is coming out with Viber Out which is an international calling service. But the only disadvantage is that there is no blocking service and once a number is added on to your phone, you can disturb another person any way you want. Viber is a free calling and messaging service that requires an Active Internet Connection.
