We are using this to get the MCC & MNC  let networkInfo = CTTelephonyNetworkInfo()     var carrier: [String:CTCarrier]? = nil           if #available(iOS 13.0, *) {       guard let str = networkInfo.dataServiceIdentifier else {         UIApplication.shared.endBackgroundTask(bgTask)         return ("","") }       carrier = networkInfo.serviceSubscriberCellularProviders       let ctCarrier = carrier?[str]       guard let _ = ctCarrier?.mobileCountryCode, let _ = ctCarrier?.mobileNetworkCode else {         UIApplication.shared.endBackgroundTask(bgTask)         return ("","")}       UIApplication.shared.endBackgroundTask(bgTask)       //NewChanges       return ((ctCarrier?.mobileCountryCode ?? ""), (ctCarrier?.mobileNetworkCode ?? ""))       //return ((ctCarrier?.mobileCountryCode!)!, (ctCarrier?.mobileNetworkCode!)!)             }
