You can switch the plan to FreedomPop's free service at anytime.
Brad's Deals Editor Michael,
Get a FreedomPop 3-in-1 SIM card for $0.99 and you'll get a free month of unlimited talk and text, and 2GB of data at FreedomPop. Select Super Saver shipping during checkout to get free shipping. This is the lowest price we found for one by $13. You'll be charged $98.88 every six months after the free trial month is up, but you can switch to FreedomPop's free 200MB, 500 minute, and 200 text plan at anytime. If don't drop down to the free service tier, and continue your service after the free one-month trial, the $24.99 monthly fee will drop to $12.99 for your first six months. These SIM cards are compatible with any unlocked GSM phone. Sales tax is charged in some states.
