Earlier this month, BlackBerry added BBM Voice to the Android beta channel. A new report from Times of India cites that BBM Voice will be arriving on both iOS and Android, in non-beta state, in February. The service will enable users to make free calls to other BBM users over WiFi. Thus, BlackBerry's software will effectively be competing against the likes of Viber, Line etc.
Do you happen to use any of these services at the moment? Would you make the switch to BBM Voice next month? I would most certainly give it a shot.
