Blackberry introduces free wi-fi calls via BBM

  • Blackberry has launched a service offering free wi-fi calls to users via its own software.

    Research In Motion (RIM) has added the feature to its Blackberry Messenger (BBM) app, which is used as an alternative to text messages.

    BBM Voice will only work if both caller and recipient are using the program.

    However, it still lacks the video chat service and 3G-support seen in rival Apple's Facetime, Microsoft's Skype and Google+ Hangouts.

    The launch of BBM Voice comes in a bid to keep users loyal to the platform ahead of the delayed release of the Blackberry 10 operating system.

    The Blackberry 10 system is expected to be launched on January 30.
