After instant rebate, the Microsoft Lumia 640 will be just $39 at MetroPCS
Another leaked image from a company memo shows that the Microsoft Lumia 640 will be priced at $129 for customers of the pre-paid carrier. But a $90 instant rebate means that you'll be paying $39 for the phone.
The Microsoft Lumia 640 features a 5-inch, 720 x 1280 resolution screen protected by Gorilla Glass 3. The pixel density works out to 294ppi and the device is driven by a Snapdragon 400 chipset. The latter contains a quad-core 1.2GHz CPU and the Adreno 305 GPU. 1GB of RAM is inside with 8GB of internal storage. Need more memory? That is what the 128GB capacity microSD slot is for. A 2500mAh battery keeps the lights on and Windows Phone 8.1 is pre-installed along with the Lumia Denim firmware update.
Seems like a good deal for those who prefer to pre-pay for their wireless service. Either way, you most likely will be running your Lumia 640 over T-Mobile's network.
