I just recieved a used KIn Twom and I planned on using it to replace my Cosmos Touch. I was not looking for a smart phone so I figured the Kin Twom would be perfect since it did not require a data plan and was simple enough for me. When I tried to activate it online it says "Your Device Change request failed and cannot be completed online. Please contact Customer Service" and the same thing when I call *228, I don't understand why this is happening. If someone could please help out that would be greatly appreciated.
