Lumia 635

As previously promised, Sprint's no-contract subsidiaries Boost Mobile and Virgin Mobile have started selling the Lumia 635 with Windows Phone 8.1 installed, for the price of $99.99.

Boost Mobile will sell the 4.5-inch smartphone in a cyan color, while Virgin Mobile is scheduled to sell the Lumia 635 today in a white color. Sprint postpaid customers can get the Lumia on January 16 but there's no word yet on pricing plans.

All three plans offer unlimited talk, text and data, but the $35 a month plan has 1GB of high speed data, while the $45 a month plan includes 5GB of high speed data. The $55 a month plan includes 10GB of high speed data.
