I have a FreedomPop phone and I have great service, and it's free forever. That said, I would never recommend FP to anyone, as it took me 3+ months to get my phone delivered to me, and that was after calling support multiple times and being lied to by managers (twice in writing by email) that I was put on an "express shipping" list. Each time I called back, there was no record of them putting me on express and I was again promised that I was "on the list now." Fucking shady as all shit.
BUT now I have free service, so...
