Hi All, I have an evo that replaced my htc touch so I have been with Sprint for a while. My problem is that when I roam and then try to place a phone call, I get a Verizon message that the Verizon network cannot authenticate my account and thus does not allow me to place a phone call through thier network. This first started on my touch phone and I thought it was just a touch problem. Now that I have the Evo, it has happened to me whenever I'm roaming. I called Sprint and they were no help what so ever. The CS kept telling me that they cannot guarentee roaming phone calls. Anyone have any idea what I should do? What is the point of have free roaming if you can't roam?
