FreedomPop offers its FreedomPop 4G LTE Nationwide SIM Kit bundled with 1GB of Bonus Data, a FreedomPop Premium Unlimited Talk, Text, 2GB 4G LTE Data 1-Month Trial, and a FreedomPop Premium Plus 1-Month Trial for 99 cents with free shipping. That's a buck under our February mention, which was bundled with a selfie stick, a $67 savings, and the best deal we've seen for a 4G SIM kit from FreedomPop. It's compatible with most unlocked GSM smartphones.

Note: Be sure to switch to the free 200MB/month data plan before your free monthly trials expire; otherwise, you'll be billed $32.98 for every additional month.
