Question

Is there a way to get information about the carrier of iPhones programmatically?

Answer 1

1st Import #import <CoreTelephony/CTTelephonyNetworkInfo.h> as well as #import <CoreTelephony/CTCarrier.h>
(make sure you have the CoreTelephone.framework installed too).

CTTelephonyNetworkInfo *phoneInfo = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *phoneCarrier = [phoneInfo subscriberCellularProvider];
NSLog(@"Carrier = %@", [phoneCarrier carrierName]);
[phoneInfo release];
