I can understand people being upset too, but like you said, it's such a new service that there will be issues that support reps don't have documentation for. The first person I talked to missed a step and didn't try switching my carrier, but the second person did a few more things to get me up and running and able to make and receive calls. There's nothing like selling a service to a couple of thousand people to find out where the bugs are.
Even with the issue I'm having now, which will hopefully be resolved with the new sim card, I really do like the service. The call quality is just so much better and it's saving me $20 a month, maybe more. And that was with an employee plan at Sprint. So far, the trade-off is definitely worth it.
