A leaked internal memo suggested that T-Mobile would begin carrying Microsoft's budget Lumia 640 smartphone from June 17th, and so it has proved. The handset can be snapped up through T-Mo for the price of $130, or $5.41 per month over a 24-month contract.
The Windows Phone handset is great value for its low price, and seems a very clear attempt by Microsoft to push more consumers in the direction of its mobile platform. WP is, after all, still a considerable way off iOS and Android in terms of reach as Redmond looks ahead to Windows 10. But the Office maker will be hoping that devices like the 640 and its partner-in-crime, the 640 XL, help to boost uptake and enrich its ecosystem.
The Lumia 640 includes a 5-inch, 720 x 1280 LCD display, equating to a very respectable 294 pixels per-inch. Under the hood, you get a quad-core, 1.2 GHz Snapdragon 400 SoC, 1 GB of RAM and 8 gigs of on-board storage. That's not a lot of default real estate, but if you do need more, there's a microSD slot that can read cards of up to 128 GB.
Camera-wise, you get an 8-megapixel shooter to the rear, and a 1-megapixel effort on the front. There's 4G LTE support for speedy cellular connectivity, and the entire operation is kept ticking over by means of the 2500 mAh battery.
