FreedomPop offers the Netgear Mingle LTE Hotspot for FreedomPop with a FreedomPop 2-Week Premium Talk, Text, and 2GB 4G LTE Data Trial and a FreedomPop Premier Service 2-Week Trial for $9.99 with free shipping. (The hotspot itself is free, but there's a $9.99 activation fee.) That's a savings of $190 and the lowest price we could find. It features an LCD display and battery life of over 12 hours.

Be sure to cancel your trials to avoid any ongoing payments.
