The Nokia Lumia 635 is an entry-level model that will also be available from AT&T and T-Mobile's pre-paid house, MetroPCS. With a 4.5 inch LCD screen offering 480 x 854 resolution, the Nokia Lumia 635 Monarch is powered by a quad-core 1.2GHz Snapdragon 400 CPU. 512MB of RAM is inside, along with 8GB of native storage. Thankfully, the microSD slot on the phone has a 128GB capacity. A 5MP front-facing snapper with an f/2.4 aperture is included, and an 1830mAh cell keeps the lights on.
U.S. carriers are beginning to brand Nokia's new handsets with names instead of numbers. Verizon named the Nokia Lumia 929 the Nokia Lumia Icon and now we have the Nokia Monarch. T-Mobile has big plans for the new handset, with expectations that the device could outsell the Nokia Lumia 521. That model is the T-Mobile branded version of the Nokia Lumia 520, the largest selling Windows Phone model of all time.
