Is there API for checking if eSIM is installed in iphone?

Question

I need to check, is esim installed in iphone. Using react-native for creating app. Found react-native-carrier-info which uses CTTelephonyNetworkInfo and CTCarrier

Can CTTelephonyNetworkInfo and CTCarrier show if esim installed or some info about this to make such conclusion? On simulator I could not see any info

Read coretelephony But I am not sure, is there native api for this task or which api can help me to make such conclusion

In Swift, if you want to check eSim connectivity only, you can :

  // First, check if the currentRadioAccessTechnology is nil
  // It means that no physical Sim card is inserted
  let telephonyInfo = CTTelephonyNetworkInfo()
  if telephonyInfo.currentRadioAccessTechnology == nil {
    // Next, on iOS 12 only, you can check the number of services connected
    // With the new serviceCurrentRadioAccessTechnology property
    if #available(iOS 12, *) {
      if let radioTechnologies =
        telephonyInfo.serviceCurrentRadioAccessTechnology, !radioTechnologies.isEmpty {
        // One or more radio services has been detected,
        // the user has one (ore more) eSim package connected to a network
      }
    }
  }

You can reinforce checking by using the new supportsCellularPlan() method on CTCellularPlanProvisioning.

I hope that is to help you:

Basically do you need to create a Library to access the native library in Objective-C:

1 - npm install -g react-native-create-library
2 - react-native-create-library MyLibrary
3 - npm install

And into a new Library do you implement your access a native library:

#import <React/RCTBridgeModule.h>

@interface NetworkInfo : NSObject <RCTBridgeModule>
@end

Implementation:

// NetworkInfo.m
#import "NetworkInfo.h"
#import <React/RCTLog.h>

@implementation NetworkInfo

// To export a module named NetworkInfo
RCT_EXPORT_MODULE();

RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location)
{
  RCTLogInfo(@"Pretending to create an event %@ at %@", name, location);
}

@end

And in your Javascript:

import {NativeModules} from 'react-native';
var NetworkInfo = NativeModules.NetworkInfo;

....your code

Thanks for answer. What Is NetworkInfo api? I could not find it on https://developer.apple.com/documentation?changes=latest_minor And NetworkInfo - will provide me any info about esim ? – teacake Apr 25 '19 at 08:42
The NetworkInfo was the name that I put for example, do you put the name that you to want. The class created in this example to able access the native library´s objective c and you can get information the eSim through the library describe here https://developer.apple.com/documentation/coretelephony and to the solution to your request look here https://stackoverflow.com/questions/13644502/detect-if-sim-card-is-available-in-iphone-programmatically – Luciano Nascimento Apr 25 '19 at 12:46
Oh I see. But the main question is - which native api can help me to get info about esim ( installed or not or may be help me to make such conclusion). and seems CTTelephonyNetworkInfo and CTCarrier do not help me with my problem according to https://stackoverflow.com/a/55520052/9136852 – teacake Apr 25 '19 at 14:07

So, I try to create a example to you when I arrive in my home, at the moment I´m in my work. Sorry not to help you right now. :( – Luciano Nascimento Apr 25 '19 at 15:12

Hello! I implement a example and put it on git https://github.com/lucklpn/SimCardInfo I used the example that I found in this site https://www.npmjs.com/package/react-native-carrier-info I did find easier to implement this. I hope to help you! ;) – Luciano Nascimento Apr 27 '19 at 02:06
Thank you for helping. I will test this in few days – teacake Apr 29 '19 at 09:07

Make it simple!

Supports iOS 12+, Make sure to test it on eSim supported devices.

import CoreTelephony

func eSimSupported() -> Bool {
    let telephonyInfo = CTTelephonyNetworkInfo()
    guard let radioTechnologies =
            telephonyInfo.serviceCurrentRadioAccessTechnology,
          !radioTechnologies.isEmpty else {
        return false
    }
    return true
}

print("eSimSupported = \(eSimSupported())")

Is there API for checking if eSIM is installed in iphone?
