Voice-over-Internet-protocol calling has made its way across the pond for Facebook Messenger users, as the social network updated its iOS version of the app in the U.K. to allow users there to make free VoIP calls.

The Next Web reported on the update in the U.K., which joins Canada and the U.S. on the short list of countries where free VoIP calling via Facebook Messenger is available.

Free calling via VoIP is not yet available for Android Facebook Messenger users in the U.K.
