#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTTelephonyNetworkInfo.h>

// Setup the Network Info and create a CTCarrier object
CTTelephonyNetworkInfo *networkInfo = [[[CTTelephonyNetworkInfo alloc] init] autorelease];
CTCarrier *carrier = [networkInfo subscriberCellularProvider];

// Get carrier name
NSString *carrierName = [carrier carrierName];
if (carrierName != nil)
  NSLog(@"Carrier: %@", carrierName);

// Get mobile country code
NSString *mcc = [carrier mobileCountryCode];
if (mcc != nil)
  NSLog(@"Mobile Country Code (MCC): %@", mcc);

NSString *mnc = [carrier mobileNetworkCode];
