Viber Messenger App
Viber is a VoIP tool that allows smartphone
users to make free voice and video calls among
them worldwide and to share free instant
messages with multimedia attachments.
It is one of the most popular communication
apps in certain regions of the world, but is and
has always remained in the shadow of Skype
and WhatsApp.
With above five hundred million users , Viber
is one of the key players on the market. It uses your mobile
number to identify you on the network and allows you
to communicate using VoIP for free bypassing your
mobile carrier.
In December 2013, Viber officially launched
Viber Out , a feature that provides users the
option to call mobile and landline numbers
via VoIP without the need for the application.
The application allows unlimited free voice and video
calls and text messages to other Viber users.
Viber also allows to post and send photos and map
locations.
Viber Out allows to make calls to non-Viber,
landline and mobile numbers at cheaper VoIP rates .
The app is available for most platforms, including iOS,
Android, Windows Phone and BlackBerry.
On Viber, no need to register with username
and password or aliases; we use our mobile
phone number.
Although, Viber with a couple hundred million users,
and its cheap calling to landline and mobile numbers,
its popularity is decreasing, its quality is
relatively poorer than Skype and WhatsApp, and it
does not offer secure and private communication.
The app isn’t very heavy on resources and installs
quite quickly. It can be run in the background, taking
advantage of the multitasking possibility of new
smartphones.
Viber does not use the GSM (Global System for Mobile
Communications) service to channel the calls and messages.
we will need to have Internet connection through
either Wi-Fi or 3G.
• Things will remain free if you use Wi-Fi,
with chances of maintained good call quality,
but you will then be terribly limited in mobility.
• When you use 3G on the move, take into consideration
that you would be paying for each megabyte of
data used on your data plan.
Viber also has a version for desktop and laptop computers,
such that you can remain connected while on your computer.
Viber Media was founded in 2010 in Tel Aviv, Israel.
In 2014, it is bought for $900 millions
by Rakuten, the Japanese online trading giant.
