From early January, Facebook had begun testing free VoIP calling, with a view to offering this service over Wi-Fi and 3G/4G cellular networks for Messenger for iPhone users residing in Canada. The company had also promised that a US launch of the same could be expected shortly. Facebook has fulfilled its promise and US users can now access the new calling button on their app.
Users do not need to install any upgrade via the App Store in order to avail this service. Messenger for iPhone users who would like to make a call to another similar user merely need to open a conversation with that other party, tap the "i" button and then tap Free Call. The other party gets a push notification of the awaiting call.
This new service is especially useful for those who would like to conserve their mobile phone talk minutes. This move also puts Facebook on top of the heap of free VoIP providers.
Facebook has not yet announced anything about an international rollout of these services, or if it would consider offering the same for Android devices as well. Anyway, here is hoping that the company would include all those things soon. Personally, I am a diehard Android fan and can't wait for this service to kick off on this OS as well!
Have you tried Facebook's free VoIP service? What do you think about it?
