The Lumia 630 and Lumia 635 were announced by Nokia during the first keynote at Microsoft’s Build 2014 conference. The Lumia 630 and Lumia 635 are identically phones on the outside, but have a few slight variations internally. The Lumia 630 series as a whole is meant to be an inexpensive handset for emerging markets.

The Lumia 630 is notable for coming in either a single-SIM or dual-SIM model. While the Lumia 635 is a single-SIM phone, but has 4G/LTE connectivity that the Lumia 630 omits. Other than that, the Lumia 630s are packing the same specs on the inside and out.

Up front is a 4.5-inch display where you’ll spend most of your time interacting with the Lumia 630/635. It’s not full HD, but it is still a high quality display. You get an IPS ClearBlack display running at a 854 x 480 resolution. Inside is a Snapdragon 400 quad-core processor running at 1.2 GHz.

The Lumia 630 and Lumia 635 are packing 512 MB of RAM in the memory department. You also get 8 GB of internal storage, but can expand that space with a MicroSD card.

Colors are plentiful with the Lumia 630 and Lumia 635. You can get them in either green, orange, yellow, white or black. The polycarbonate backs are swappable, so you can switch up the color of your phone to match whatever outfit you’re wearing (or to match your mood).

The Lumia 630 and Lumia 635 will be available starting May 2014. They will initially be available in Asia, Russia, China, India and Europe. The United States can look forward to these devices in July 2014. The single-SIM Lumia 630 will be priced at $159 and the dual-SIM version of the Lumia 630 at $169. The Lumia 635 with its 4G/LTE connectivity will retail for $189.
