FreedomPop offers its refurbished FreedomPop Wireless 4G LTE 803S Hotspot bundled with a 2GB 4G/3G Data Plan 1-Month Trial for $29.99 with free shipping. That's a savings of $135 and the lowest total price we could find. (For further comparison, we saw a refurb hotspot bundled with 2.5GB data for $40 shipped in March.) It provides WiFi for up to eight devices.
Note: Be sure to switch to the free 500MB/month plan and cancel 2GB trial before your initial free month expires, or you'll be billed $19.99 for every additional month. Uncheck "Rollover unused data" in your cart to remove the $3.99 fee. A 90-day FreedomPop warranty applies.
