Any Update?

Below function we are using static func getMccMnc() -> (mcc: String, mnc: String) {     let bgTask = UIApplication.shared.beginBackgroundTask {       print("BackgroundTask Expired")     }           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)       return ((ctCarrier?.mobileCountryCode ?? ""), (ctCarrier?.mobileNetworkCode ?? ""))             }

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 ?? ""))} This code give wrong MNC in Roaming
