For those of you looking to get a Lumia 640 on T-Mobile, the Microsoft Store is now listing the device as "coming soon" with a price of $89.
Specifically, Microsoft is listing the white version of the Lumia 640 for T-Mobile at a very budget-friendly price of $89 though it isn't yet available for purchase. This is the no-contract pricing, too.
For that $89, you'll score a 5-inch 720p display, a 1.2GHz quad-core Snapdragon 400 processor, 1GB of RAM, 8GB of expandable storage, an 8MP rear shooter, and a 1MP front-facing camera. All of this runs off of a 2,500mAh battery on Windows Phone 8.1 Update 2.
This marks the first look we've gotten at carrier pricing for the Lumia 640 in the U.S.. There's no word on when Microsoft might have it available for purchase, but it shouldn't be too long now.
Update: Microsoft has since pulled the store listing. In all likelihood, it was posted prematurely, as T-Mobile has not yet announced pricing and availability.
