FreedomPop offers its FreedomPop 3-in-1 Global SIM Kit, bundled with a FreedomPop Global Unlimited Talk, Text, and 1GB HSPA+/3G Data 1-Month Trial, and FreedomPop Premium Plus 1-Month Trial, for 99 cents with free shipping. That's tied with our mention from two weeks ago, which included a selfie stick and power bank, and $4 under the lowest total price we could find for just the SIM kit elsewhere. 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 $27.98 for every additional month.
