No Sim Card Installed Pop up showing twice in calling feature - objective-c

Question

I am using calling feature in App . Problem is that if no sim card installed in device then "No sim card installed" Alert view showing 2 times . I am using this code :
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:phoneNumber]])
{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
}
Note: 1st Alert view automatically hide and again 2nd one is appearing .

Answer 1

Finally Found alternate solution for this :
Actually this is not an issue , This is transition effect :
To resolve it i have integrated below code before calling feature :
#import CoreTelephony;
CTTelephonyNetworkInfo *networkInfo = [CTTelephonyNetworkInfo new];
CTCarrier *carrier = [networkInfo subscriberCellularProvider];
if (!carrier.isoCountryCode) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"No SIM Card Installed" message:nil delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
else{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
}
