FreedomPop offers its factory-refurbished FreedomSpot MiFi 4082 Wireless Hotspot bundled with a combined 2.5GB 4G/3G Data Plan 1-Month Trial (2GB plan + 500MB plan) for $29.99 with free shipping. That's tied with its Black Friday deal and still $10 less than the best price we could find for a plan with only 500GB of data. It features a battery life of up to six hours. A 90-day FreedomPop warranty applies.
Note: After the trial ends you can continue with the 2GB plan for $19.99 per month or switch to a free 500MB month-to-month plan.
