Facebook has updated its Messenger App by adding VoIP (Voice over Internet Protocol) calling features for Canadian Android users.

With this update (version 2.3), Android users in Canada can make fee calls using the Facebook Messenger app over VoIP to their Facebook friends in Canada as well as iOS users in the United States.

Along with the free calling functionality, the update for Messenger app on Android also includes group conversation feature as well as the ability to name the group conversation. Facebook also listed "other improvements and bug fixes" on the Google Play Store, but did not mention what the new improvements are.

The Free calling can be used over Wi-Fi connection (private or public) or existing data connection on user's device.

Back in January, the social networking giant released a similar update for its iOS app which enabled the functionality of calling through Facebook Messenger app for Apple users in the United States. Facebook rolled out the feature in the U.S. after a month's trail in Canada, according to Inside Facebook.

Last month, Facebook also updated (version 5.5) its Facebook app on iOS platform for the U.S. users, which allows making free calls over VoIP just like the Messenger app. The new version of Facebook app will also bring many changes including the new button design which makes it easy to 'like', comment and share post.
