FreedomPop offers its FreedomPop 3-in-1 SIM Card Kit for GSM Connected Cars bundled with a FreedomPop Premium GSM 2GB 4G LTE Data Trial and FreedomPop Premier Trial for 1 cent with free shipping. That's a savings of $48 and the lowest price we could find. This SIM card works with GSM connected cars for GPS, streaming music, and as a WiFi hotspot.

Note: Be sure to switch to the free 200MB 4G LTE monthly plan before your trials expire; otherwise, you'll be billed $32.98 each month.
