FreedomPop offers its refurbished FreedomPop SuperNova Wireless 4G LTE Hotspot bundled with a 4GB 4G/3G Data Plan 1-Month Trial, 6-Months of Double Data, and Premier Service 1-Month Trial for $79.99 with free shipping. That's a savings of $165, the same price as our June mention (which only included a 2GB trial), and the lowest total price we could find. It provides WiFi for up to eight devices.
Note: Be sure to switch to the free 500MB/month plan and cancel the 4GB trial and Premier Service trial before your free month expires to avoid being billed $19.99 and $9.99 (respectively) for each additional month. A 90-day FreedomPop warranty applies.
