Microsoft's cheapest Windows 10 phone, the Lumia 550, now costs only $119 in the US8
The Lumia 550 is compatible with the networks of AT&T and T-Mobile (LTE included), and is, at the moment, the cheapest Windows 10 handset available in the US. Obviously, this is no high-end device. Its features include a 4.7-inch display with 720 x 1280 pixels, a 5 MP rear camera, 1 GB of RAM, and 8 GB of expandable storage space. The smartphone is powered by Qualcomm's frugal (and not terribly fast) quad-core Snapdragon 210 processor, and includes a 2100 mAh battery.
An alternative to the Lumia 550 would be the Alcatel OneTouch Fierce XL - this also runs Windows 10 (offering relatively similar features, though its screen is a larger, 5.5-inch one), and is currently sold by T-Mobile for $139.
So, are you planning to get yourself a cheap Windows 10 phone anytime soon?
