FreedomPop offers its FreedomPop 4G LTE Nationwide 3-in-1 SIM Kit bundled with a FreedomPop Premium Unlimited Talk, Text, and 2GB 4G LTE Data 1-Month Trial, FreedomPop Phone Premier 1-Month Trial, and 2GB of Bonus Data for 1 cent with free shipping. That's a savings of $73 and tied with last month's mention. (For further comparison, you'd pay at least a buck more for just the SIM kit elsewhere.) It's compatible with most unlocked GSM smartphones.

Note: Be sure to switch to the free 200 minutes/500 texts/200MB data per month plan before your free trial expires; otherwise, you'll be billed $24.99 for every additional month. If you don't cancel the FreedomPop Phone Premier trial, that will be an additional $7.99 per month.
