Viber review

Viber combines the two kinds of calling on this list in one app. Calls between Viber users are free, with group voice and video calls, and chats stay synced between phone and desktop so you can move a call to your computer with one tap. For people who are not on Viber, Viber Out calls any landline or mobile number with no commitment and no connection fee. You can buy prepaid credit or a monthly plan, including a World subscription with unlimited minutes and a one-week free trial, though trials are limited to one per customer and unlimited plans exclude special, premium and non-geographic numbers under a fair usage policy. We could not confirm US dollar prices: Viber's calling card pages showed euros from our location, so check the price in the app before you buy. Viber offers desktop apps for Windows, Mac and Linux, which is wider than most rivals here.
