FreedomPop announced last year that they would give customers 1GB of free 4G service per month if customers in exchange purchased the FreedomSleeve for $99.
Today the company amended that promise and instead offered 500 MB of free data per month. Still a decent deal.
FreedomPop is also allowing customers to return the sleeve after they are finished with it for a full refund.
This case would be excellent for someone who wants more data but doesn't want to pay the carriers high prices. A user could elect to receive the cheapest data package with their mobile carrier and use the FreedomSleeve to supplement the data plan.
