The New York Times has a fantastic article on problems facing consumers trying to switch carriers. One reporter’s misadventures in carrier switching despite all the FCC promises.

With all of that machinery in place, the Federal Communications Commission assured consumers at its Web site that “your phone number should work within a few hours of your request to change wireless providers.”
Well as we read in this article, wireless carriers were quick to charge for number portability, but not so quick on service.
