Unable to load network list

[mdoyle]

Yesterday I tried to change my network from orange uk to t-mobile as a test as they have a network share which has been activated on my sim card. Selecting t-mobile failed to bring up a signal and now I have a no service MSG on my iPhone. I've tried going back into carrier and get unable to load network list error. I've tried resetting using power and home key reset network settings and reset phone settings and a turn off and on and removing the sim card. But can't resolve it turned 3G off and powered off not resolved any ideas I need help. Sadly I work for orange which I'm embarrassed to admit
