T-Mobile Lumia 635 quick look and first impressions

Last week, T-Mobile US and Microsoft began selling the Nokia Lumia 635, the speedy brother of the budget Lumia 630 with 4G LTE. The Lumia 635 is replacing the older (and cheaper) Lumia 521, which is one of T-Mobile's best selling Windows Phones to date.

Announced last week, the Lumia 635 runs for $0 down + $7 per month for 24 months ($168) with a postpaid Simple Choice plan on T-Mobile. Alternatively, it is also soon available on MetroPCS for a flat-rate of $99 prepaid. The Lumia 635 comes in white although people can optionally purchase shells to change the color to bright green, bright orange or yellow.

The Lumia 635 has some decent specifications considering its price range, but it forgoes a few things too.

  • Windows Phone 8.1 build 12397; Lumia Cyan
  • 4.5-inch IPS LCD display with ClearBlack and Gorilla Glass 3
  • 854 x 480 display resolution (800 x 480 + virtual keys)
  • 1.2 GHz Quad-core Snapdragon processor
  • 5 MP rear camera, no LED flash
  • 8 GB internal memory (3.33 GB free); micro SD expandable up to 128 GB
  • 512 MB of RAM
  • 4G LTE; T-Mobile Wi-Fi calling enabled
  • 1830 mAh replaceable battery
  • 5 x 66.7 x 9.2 mm
  • 134 grams

The Lumia 635 though omits an ambient light sensor, front facing camera, physical camera button and NFC to keep costs down. The phone also comes with an anemic 512 MB of RAM, which limits its ability to run a small group of modern video games.

At its core, the Lumia 635 is a solid update from the Lumia 521, but it remains to be seen how well it can compete against low-cost Android devices and if it can continue the Lumia 521's success.
