Let be me very clear about the Fig Flip; Any of the 3 networks may take some effort to get it working right, even T-Mobile sometimes has some issues with it. Its just the consequence of using remodeled chinese parts (and we all know what I mean by chinese... even if Apple makes their phones in China too....)
Most people just pop a SIM in and have no issue, while other's face many problems. If you want to try this phone, be prepared to work a bit to set it up. Or better yet buy from somebody that know the phone and the services and can help you set it up., Not from the website or a random ad. And know the software is also a bit half-baked and needs a bunch more updates. (Also note that as of today's update, there is no more video player/recorder)
