BlackBerry says it will make its BBM text messaging system available to two more types of smartphones, those running the Windows operating system and the Nokia X platform.
The company said Monday at a trade conference that BBM will be a free download from the Windows Phone Store this summer and the version for Nokia X will be available when the platform launches.
BBM has been considered one of the reasons for BlackBerry's success in wooing customers to earlier versions of its smartphones.
BlackBerry stock climbed 8.5 per cent or 85 cents to $11.02 in Monday morning trading in Toronto before settling at $10.87 at the close.
The Waterloo-based company was a pioneer in the smartphone industry but has been replaced as market leader by devices using the Android operating system and the iPhone.
The company has already made BlackBerry Messenger available to Apple iPhones and Android devices -- although only after some delays.
Spreading the messenger
BlackBerry has been expanding the reach of BBM as a way to maintain loyal client organizations that can choose from a range of devices.
The company has also introduced new features for BBM that could make the service a potential revenue stream through mobile advertising.
Two weeks ago, BlackBerry confirmed the departure of Andrew Bocking, who headed BlackBerry Messenger and said responsibility for the BBM team had been assigned to John Sims, president of Global Enterprise Solutions.
BlackBerry head John Chen has made many changes in the company's executive offices since taking over as chairman and CEO in November.
"BBM continues to grow in popularity as millions of people use our mobile platform for chatting and connecting with friends or colleagues, and we are very excited that we will soon welcome Windows Phone and Nokia X users to the BBM community," Sims said Monday in a statement from a mobile tech trade show in Barcelona.
