When i started my Tmobile contract about a month ago i had to call customer support twice; once to help set up my data connect and a second time to help with voicemail set up. Both time i spoke to people with "american" accents. When one repesentative didnt know how to solve the problem she sent me to the next teir support level where my problem was solved quickly.

I've had horrible tech support with other services but I'd say Tmobile is one of the better experiences i've had.
