Former Research In Motion co-chief executive Jim Balsillie sought a radical shift in strategy before he stepped down, Reuters reported on Friday. Citing two unnamed sources, the publication claims Balsillie wanted to allow wireless companies in North America and Europe to use RIM’s proprietary network for services on non-BlackBerry devices. The plan would help carriers entice customers to upgrade from feature phones to smartphones and allow them to offer inexpensive data plans that were limited to social media and instant messaging via the company’s BlackBerry Messenger service. Despite RIM’s network bringing in nearly $1 billion each quarter, the plan was vetoed, leading to Balsillie’s resignation soon after heĀ stepped down as co-CEO. The Blackberry-maker will instead focus more on its next-generation BlackBerry 10-powered smartphones, and on regaining enterpriseĀ momentum.
