I have no idea why it doesn't work. The network settings are provided to your phone by the carrier, not by Apple. Have you checked for a carrier update? Go to Settings/General/About and click on the name of the carrier. If a carrier update is available it will be installed. If not perhaps the carrier has not yet issued an update for the current iOS version.
