Their limitations make sense, you just have to look at your own usage and decide if it will work for you. I don't feel like they are hiding anything, I read through their entire site yesterday and it was all there in black and white.

The only concern I do have is how well will actually work? Does it switch seamlessly when I leave the range of my wifi like the site claims. A co-worker signed up and has one on the way, so we will find out soon.

At least they are more upfront about the "unlimited" rules than other carriers like say AT&T. Even Sprint is close to killing off their unlimited plans.
