FreedomPop offers its factory-refurbished FreedomPop Freedom Stick U770 4G/3G USB Modem bundled with a combined 2.5GB 4G/3G Data Plan 1-Month Trial (2GB plan + 500MB plan) for $19.99 with free shipping. That's tied with our March refurb mention and the lowest total price we could find by $12. 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.
