Lenovo has been previously listed as a partner for Microsoft’s Windows Phone 8.1 but they haven’t released any device yet. Now, with Windows 10 coming out, it seems Lenovo is finally entering Microsoft’s mobile space. According to a blog post from Microsoft, they will be debuting in 190 countries and that Lenovo will be creating a Windows-powered phone. It is said to be available in the middle of 2015 through Chinese carrier China Mobile.
According to CNET, China Mobile is the nation's largest carrier. They have around 808 million subscribers, which certainly can help boost both Lenovo’s and Microsoft’s efforts in the mobile space. It isn’t known yet though what type of device it’ll be or if it’ll make its way out of China. But getting into that market will be important for Microsoft especially as they look to roll out Windows 10 to all devices (from phones, tablets, to PCs) and make its presence known in the mobile device space. China would be a good place to start as it has the largest smartphone market.
