BBM was recently made available to third-party devices and raked in 10 million downloads within the first 24 hours
BBM users on Android and iPhone will now be able to make free voice calls to BBM contacts over a Wi-Fi or cellular data connection with BBM Voice, as well as access BBM Channels, a broadcast service, BlackBerry said in a statement.
The Canadian smartphone maker in October last year launched BBM for rival Android- and iOS-based handsets and the app since then has been downloaded on over 40 million such handsets.
Smartphone maker BlackBerry has introduced new privacy and control features for its messaging app BBM, allowing users to delete messages from chats and share pictures for short duration of time.
The system will wed BlackBerry's security platform with the South Korean company's own security software for its Galaxy devices.
