If you’ve got Facebook’s Messenger app downloaded on your Android smartphone, you no doubt already known that the Messenger app has been blessed with voice over IP calling technology.

You’ll likely remember that VoIP for Messenger users on iOS has been available to users in the United States for a few months now, and the U.S. is the latest of 24 total countries that are now enjoying Facebook’s expanding VoIP service.

The VoIP feature should have been rolled out to all Android users over the course of the day yesterday, so if you haven’t received the update, you’ll want to double check the Google Play store to make sure you haven’t missed it, though it shouldn’t require a manual update. If you’re not sure whether you have the feature or not, you can visit a Facebook friend’s profile and simply click the “i” icon and then the “free call” option to initiate a VoIP call.

This is a good option for those of you who aren’t content with the many VoIP options currently available to you or for those who spend most of their daily lives on the social network.
