The biggest Indian mobile company is having quite a good year. According to several leads, Micromax has just decided to cross the Rs. 20K point and enter into the premium segment with a Windows phone.

At this year’s BUILD conference, Microsoft announced Micromax as one of its latest Windows Phone partners. Now we got some details to add about the upcoming Windows Phone from one of India’s biggest handset makers.

Microsoft Executive VP (Operating Systems) Terry Myerson on Wednesday said: “We are thrilled to welcome 11 new Windows Phone partners since Mobile World Congress in February, with the addition of Micromax and Prestigio just announced today”.

Besides, the software giant has also announced that it will offer its Windows operating system free to smartphone and tablet makers (for devices with screen-sizes less than 9-inches), a move that will help the firm compete with Google’s Android and Apple’s iOS in the fiercely competitive smart devices market.

Up till now, the details of the Micromax Windows Phones had been sketchy but now, thanks to Twitter leakster @LeaksterInc, we have some interesting details to report.

During the Canvas 4 launch event, Rahul Sharma said that they are considering to work on other operating systems and Windows Phone 8 will be one of them. Although Rahul Sharma confirmed this but didn’t share any details on the company’s plans and the expected timeframe when they will launch the handset.

The rumored Windows smartphone by Micromax will be a premium device, which will be priced somewhere around Rs 23,000 and Rs 25,000. This smartphone is likely to debut in July.

This is sharp in contrast to the Windows plans of other Indian manufactures such as Karbonn and Lava/Xolo, who plan to bring affordable (read sub Rs 10,000) Windows Phones in India. Coming over to the specifications, the first Windows Phone by Micromax is likely to sport a 5-inch Full HD display. It will be powered by a Qualcomm Snapdragon 800 processor along with 2GB of RAM and 16GB of internal memory, which can be expanded via microSD card. There will be a 13-megapixel rear-facing camera and a 5-megapixel one on the front.

Furthermore, this smartphone will run on Windows Phone 8.1. On paper as of now, this looks like another interesting device from Micromax; however, we will like to see how the company packages it. Another interesting challenge for Micromax will be to take on the existing crop of Nokia devices such as the Lumia 720 and 820 through this offering.

The specs look pretty impressive for a Micromax Windows phone. We hope to bring you a hands on review, as soon as we can, to tell you if it’s worth the glitter.
