FreedomPop offers its refurbished FreedomPop Freedom Hub Burst 802.11n Wireless 4G Router/Modem bundled with a 10GB Data Plan 1-Month Trial for $29.99 with free shipping. That's tied with last month's mention as the lowest total price we've seen for this router bundle. (It's $78 under the best deal we could find for a new router alone elsewhere.) It features WEP, WPA, and WPA2 encryption. A 90-day FreedomPop warranty applies.
Note: The trial subscription begins once the item is shipped. Be sure to cancel your subscription before the end of the trial period, or you'll be charged $18.99 every month thereafter for 10GB of bandwidth.
