Viber app adds support for calling landline and mobile numbers

Published by at

Viber, a popular instant messaging and calling service with more than 300 million registered users, has updated their Windows Phone 8 app to version 4.1. New and updated features include support for Viber Out (making it possible to call landline and mobile number at low rates), support for sending video messages, and support for seamlessly transferring calls to a Bluetooth headset. 

Viber Out essentially allows users to call "everyone at local rates", potentially offering substantial savings over standard operator charges for voice calls. For example, calling Singapore from the UK is charged at £0.01 per minute for a landline or mobile, when using Viber Out, a saving of up to 90% over standard UK operator charges.

Given that many smartphone users are on contracts, with an allocation of inclusive minutes for local / national calls, Viber Out is going to be most useful when looking to save money when making international calls, or when roaming in another country (if using a WiFi connection). 

Like most "calling out" systems Viber Out works on prepaid system (i.e. similar to PAYG), with the ability to buy credits from within the app, or via the Viber website. Credit can be bought via Visa, MasterCard, American Express, or PayPal. Each time you make a call the appropriate amount of credit is removed from your balance. 


The lastest release of Viber also sees improvements in Viber's core messaging experience. It's now possible to send a video messages to contact and send multiple photos at one time when chatting to a contact. In an improvement to the calling experience, Viber has now made it possible for calls to be transferred to a Bluetooth headset, something that's useful if you're making a longer call in a noisy environment.

This latest update continues Viber's policy of regular updates for its Windows Phone app, which has made Viber one of the best VoIP and messaging based apps available for Microsoft's mobile platform. Along with Skype and Nimbuzz, it is one of only a handful of VoIP apps for Windows Phone that support calling numbers outside the the service's own boundaries (i.e. calling out).
