How to check if device can make a phone call (iOS 8)?

Question

On iOS <8 you could use function - (BOOL)canOpenURL:(NSURL *)url.

On iOS 8 this function returns YES, even on iPad. I guess it\'s connec

Ok, so I just encountered the same problem. Seems like iPad and iPod return YES value for canOpenURL method. Please see my answer below since this worked for me. I had a custom collection view cell and that is why had this code in my awakeFromNib file. However, you should write this code in ViewDidLoad of that perticular viewController.

Make sure to include "CoreTelephony.Framework" in your project.

Include below files in the view controller:

 #import 
 #import 

    - (void)awakeFromNib {
    // Initialization code

    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"tel://"]]) {
        // Check if iOS Device supports phone calls
        CTTelephonyNetworkInfo *netInfo = [[CTTelephonyNetworkInfo alloc] init];
        CTCarrier *carrier = [netInfo subscriberCellularProvider];
        NSString *mnc = [carrier mobileNetworkCode];
        // User will get an alert error when they will try to make a phone call in airplane mode.
        if (([mnc length] == 0)) {
            // Device cannot place a call at this time.  SIM might be removed.
        } else {
            // iOS Device is capable for making calls
        }
    } else {
        // iOS Device is not capable for making calls
    }



    if ( ! [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"sms:"]]) {
       // iOS Device is not capable to send SMS messages. 
    }
}
