1. Facebook's free call service for US iPhone Users
Facebook recently announced that iPhone users could enjoy free calls in the US over Wi-Fi
Messenger for iPhone. This new feature facilitates people from United States that allows them
to use Facebook Messenger app to place voice calls with friends using their internet connection
or Wi-Fi. The feature comes as a “Free Call” button in the existing app and the users doesn’t
have to update to take advantage of this feature.
A lot of users quoted “Free call feature is incredibly simple and useful”. But the app also
requires the receiver to have Facebook's stand-alone app installed on their phone. If the app
couldn’t sync with the receiver, the "Free Call" icon appears grey and marked out. The call
features look and feel similar to the conventional voice calls. Besides United States, facebook
has mentioned that they have started testing VoIP functionality in Canada.
Facebook has also added a voice message feature for the iPhone users. It enables the user to
send recorded messages to their Facebook friends. It works similar to a text message, whereas
the text is replaced by a bar recorded with the sender’s voice information.
