FreedomPop offers the refurbished HTC Desire 510 4G Android No-Contract Smartphone for FreedomPop, bundled with a Premium 2GB 3G/4G LTE Data 1-Month Trial and Premier Service 1-Month Trial, for $29.99 with free shipping. That's $10 under our mention from last month (which included a selfie stick) and the lowest total price we've seen for this device. (It's also at least $50 less than you'd spend for a new one elsewhere.) It features a Qualcomm Snapdragon 400 1.2GHz quad-core processor, 4.7" 480x854 touchscreen LCD, 1GB RAM, 8GB internal memory, 802.11n wireless, Bluetooth 4.0, 5-mexapixel rear camera, 1.3-megapixel front-facing camera, microSDHC card slot, and Android 4.4 OS (Kit Kat).
Note: A 90-day FreedomPop warranty applies. Be sure to switch to the free 500MB/month plan and cancel Premium Plus before your initial free month expires, or you'll be billed $32.98 for every additional month.
Update: Specs corrected.
