So a friend of mine, visiting from Austria, wants to know if its possible to use her european iPhone on T-Mobile USA's network?  Since her iPhone isnt tied to any one carrier, you would think that popping in a T-Mobile USA micro sim card would work without any kind of problem.  Unfortunatley, that isnt the case.  When she put in her T-Mobile USA micro sim, she got a message on her iPhone saying that the sim card wasnt valid. 

 

I called T-Mobile's tech support line to see if they could be of any help and all I got was "Uh uh uh uh...we dont know"

 

Any help on this would be appreciated since its impossible to get a hold of Apple's tech support and T-Mobile doesnt know anything.
