FreedomPop offers the used Netgear Unite 4G GSM No-Contract Mobile Hotspot for FreedomPop bundled with a Premium 1-Month GSM 2GB Trial for $19.99 with free shipping. That's tied with our January mention, $180 off, and the lowest price we could find. It connects with up to 10 devices and features a 2.4" LCD and data usage meter.

Note: A 90-day Freedompop warranty applies. Be sure to switch to the free 500MB/month plan before your initial free month expires, or you'll be billed $98.88 every six months.
