Did you cut the tmobile sim to micro-sim? If you did, you may want to check if you had done it properly. I had trouble in the first place, but eventually realize what I had done wrong, and get it to work.

I use this video (the last post). Pay attention to the bottom of the card (the end without the notch). This bottom edge is flush with the metal of the circuit board.

In my case, the card was cut too small, I had to try moving it a bit in order to get a good contact and signal. I use a scotch tape to tape it down (just a little piece is good enough). This trial and error may take a few times.
