iOS编程中是否有任何方法,功能或属性,我们可以通过它来识别SIM是预付费还是后付费？

我们能否以任何方式使用网络信息来区分前后？

- (NSDictionary *)fetchSSIDInformation { 
       NSArray *interfaceNames = CFBridgingRelease(CNCopySupportedInterfaces());
       NSLog(@"%s: Supported interfaces: %@", func, interfaceNames);
       NSDictionary *SSIDInfo; 
       for (NSString *interfaceName in interfaceNames)
          { 
            SSIDInfo = CFBridgingRelease( CNCopyCurrentNetworkInfo((bridge CFStringRef)interfaceName)); 
            NSLog(@"%s: %@ => %@", __func, interfaceName, SSIDInfo); 
            BOOL isNotEmpty = (SSIDInfo.count > 0); 
            if (isNotEmpty) { break; } 
          }

      return SSIDInfo;
}
