FreedomPop offers its FreedomPop 4G LTE Nationwide SIM Kit bundled with a FreedomPop Premium Unlimited Talk, Text, and 2GB 4G LTE Data 1-Month Trial and FreedomPop Premium Plus 1-Month Trial for 99 cents with free shipping. (You'll see the bundled items in cart.) That's a buck under our mention from two weeks ago (although that included 1GB of bonus data and a selfie stick), a savings of $47, and the lowest total price 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 200 minutes/500 texts/200MB data per month plan before your free monthly trials expire; otherwise, you'll be billed $32.98 for every additional month.
