你这个太麻烦，可以看下这个：

• (NSUInteger) carrierType
  {
  Class TeleNetInfo = NSClassFromString(@"CTTelephonyNetworkInfo");
  CTTelephonyNetworkInfo * info = [[TeleNetInfo alloc] init];
  CTCarrier * carrier = [info subscriberCellularProvider];
  [info release];

  if(carrier == nil)
  {
  return UIDeviceCarrierUnknown;
  }

  if(![[carrier mobileCountryCode] isEqualToString:@"460"])
  {
  return UIDeviceCarrierUnknown;
  }

  int carrierNetworkCode = [[carrier mobileNetworkCode] intValue];
  switch(carrierNetworkCode)
  {
  case 00: case 02: case 07:
  return UIDeviceCarrierChinaMobile;
  break;

      case 01: case 06:
          return UIDeviceCarrierChinaUnicom;
          break;
  
      case 03: case 05:
          return UIDeviceCarrierChinaTelecom;
          break;
  
      default:
          return UIDeviceCarrierUnknown;
          break;
  

  }

}
