FreedomPop The nation's only truly free cellular phone service, FreedomPop's "Freedom Phone" offers 200 voice minutes, 500 texts, and 500MB of free data on Sprint's 3G and LTE networks. If you want more, you can jump up to unlimited voice and text with 500MB data for $6.67 per month, or unlimited voice and text with 1GB data for $19.99 per month. Additional minutes and texts cost 1 cent each, and additional data costs 2.5 cents per MB, or $9.99 per GB. There are a few catches, though. You can't send video messages to non-FreedomPop users (use email instead, the company says), and all voice calling goes through FreedomPop's Voice over IP system (VoIP) rather than the standard Sprint voice network. FreedomPop sells a bunch of older Sprint phones, of which the best is probably the $329 Samsung Galaxy S4, and the best value is the $99.99 LG Optimus F3. It will also work with a limited (and unexplained) set of used Sprint phones.
