With purchase of at least a 1-month GoPhone plan, AT&T offers the refurbished ZTE Zmax 2 4G No-Contract Android Smartphone for AT&T for $44.99 with free shipping. That's $9 under our November mention and the lowest total price we've seen for this phone in any condition. (It's $109 under the best we could find for a new unit.) It features a 5.5" 1280x720 touchscreen LCD, Qualcomm Snapdragon 400 1.2GHz quad-core processor, 2GB RAM, 16GB storage, 802.11n wireless, Bluetooth 4.0, 8-megapixel rear-facing camera, 2-megapixel front-facing camera, microSD card slot, and Android 5.1 OS (Lollipop).

A 90-day AT&T warranty applies.
