Which version of the device and where purchased from? Just because devices have the same name doesn't mean they support the same spectrum for all carriers. If the device is a European/Asian version then it will not support all spectrum and will not work.

You might want to visit XDA and see if there is a combination firmware available for the device that would make it more compatible with T-Mobile USA.
