The Nokia Lumia 520 is a low-cost, entry level Windows Phone introduced in late February 2013 at Mobile World Congress. A variant, the Lumia 521, was created for T-Mobile US.
The device features a modest 4-inch IPS display (800 x 480), 8 GB of internal storage, micro SD expansion, 512 MB of RAM, dual-core 1 GHz Snapdragon CPU and a 5 MP rear camera. Due to its low cost, the phone lacks a front facing camera and NFC.
The Lumia 525 was also introduced to limited markets, and it features 1 GB of RAM with the same specs as the Lumia 520.
