Amazon has today announced a new addition to its suite of "Prime exclusive" smartphones, unlocked phones that are discounted because they display ads for products and services from Amazon. The new model is the Moto G Play, which sells for $99.99 and will start shipping on September 15th. Preorders for the phone start today.

The Moto G Play has a 5-inch, 720p display, Qualcomm Snapdragon 410 processor, 2GB of RAM, 16GB of storage plus microSD card expansion, a 2,800mAh battery, an 8-megapixel rear camera, and a 5-megapixel front camera. It runs Android 6.0.1 Marshmallow and is compatible with all four major networks in the US, including Sprint and Verizon. Amazon's Prime exclusive version is priced $50 below the standard version that does not have ads.

Amazon says that its other Prime exclusive phones, the Blu R1 HD and Moto G, have been two of the best-selling unlocked phones on the site. The Blu is priced below the new G Play at $49.99, while the Moto G is more expensive at $149.99.
