Back from the dead: Nokia Lumia 1520 relaunched by AT&T, Windows 10 on board
Unfortunately, the AT&T Lumia 1520 is now too expensive for a phone of its age: you can get it for $19.50 a month for 30 months, $24.38 a month for 24 months, or $584.99 outright. That's not to say that the smartphone won't serve you well, but we're having a hard time recommending it when there are plenty of newer, more powerful handsets that you can currently get for around $600 (and even less). Moreover, you can purchase an unlocked Lumia 1520 from Amazon for around $300.
If you still want to buy a Nokia Lumia 1520, you'll get features like a 6-inch 1080p display, a quad-core Snapdragon 800 processor, a good 20 MP PureView rear camera, 2 GB of RAM, and 16 GB of expandable storage space. Interested?
