How to read SIM Carrier name programmatically in iOS using Swift4 - ios

Question

Before going in-depth, let me tell you all that - Yes, I've gone through all possible solutions provided on Stack-Overflow.
Problem Statement : I'm not able to read 'CarrierName' of my available SIM using iPhone
What did I tried : I've tried two different solutions, but I'm unable to read CarrierName.
Solution 1 : When I tried this solution I've received only "Carrier" as output, instead of CarrierName.
Solution 1 :
//--------------- CodeBase : Solution1 -----------------
let networkInfo = CTTelephonyNetworkInfo()
let carrier = networkInfo.serviceSubscriberCellularProviders?.first?.value
if let carrierName = carrier?.carrierName {
cell.textLabel?.text = carrierName
}
else{
cell.textLabel?.text = "No Data"
}
//-------------------------------------------------------
Output : Carrier
Solution 2 : When I tried this solution I've received "iPhone X" as output, instead of CarrierName.
Solution 2 :
//--------------- CodeBase : Solution2 -----------------
let networkInfo = CTTelephonyNetworkInfo()
let carrier = networkInfo.serviceSubscriberCellularProviders?.first?.value
if var carrierName = carrier?.carrierName {
if carrierName.contains("Carrier"){
carrierName = self.getCarrierName() ?? "No Data"
}
else{
cell.textLabel?.text = carrierName
}
}
else{
cell.textLabel?.text = "No Data"
}
//-------------------------------------------------------
Func : getCarrierName()
//--------------- CodeBase : Part of Solution2 -----------------
func getCarrierName() -> String? {
var carrierName: String?
let typeName: (Any) -> String = { String(describing: type(of: $0)) }
let statusBar = UIApplication.shared.value(forKey: "_statusBar") as! UIView
for statusBarForegroundView in statusBar.subviews {
if typeName(statusBarForegroundView) == "UIStatusBarForegroundView" {
for statusBarItem in statusBarForegroundView.subviews {
if typeName(statusBarItem) == "UIStatusBarServiceItemView" {
carrierName = (statusBarItem.value(forKey: "_serviceString") as! String)
}
}
}
}
return carrierName
}
//-------------------------------------------------------
Output : iPhone X i.e. It returns ModelName instead of CarrierName
Can someone, please help me to get - CarrierName.

Answer 1

In my case (Xcode 11.4, Swift 5.2, iPhone 8, iOS 13.3.1), I can get the proper carrier name.
Code snippet:
import CoreTelephony
if #available(iOS 12.0, *) {
if let providers = CTTelephonyNetworkInfo().serviceSubscriberCellularProviders {
providers.forEach { (key, value) in
print("key: \(key), carrier: \(value.carrierName ?? "nil")")
}
}
} else {
let provider = CTTelephonyNetworkInfo().subscriberCellularProvider
print("carrier: \(provider?.carrierName ?? "nil")")
}
The result in console is:
key: 0000000100000001, carrier: 中国电信
