It seems to me like there needs to be far more security in place before a SIM card can be swapped out over the phone. You should need to state your SSN, answer a few security questions and maybe let them know how much you paid on your last three bills or something like that. That doesn't mitigate the risk of bribery but if you have the right software in place for the person on the line at T-Mobile or AT&T then they wouldn't be able to proceed without the proper verification. Seems like a pretty big but easy to solve problem to me.
