Detecting which SIM a incoming call is coming from android?

Question

I neeed to detect target sim card of incoming call on multiple sim devices. I have tired a lot of posts and tried many solutions, but all the solutions are outdated. Not working on newer version of Android.

I tried the below solutions, nothing helps

    int simSlot = intent.getIntExtra("simSlot", -1);
    int simId = intent.getIntExtra("simId", -1);
    int slot = intent.getIntExtra("slot", -1);

These all are returns -1

String[] array = new String[]{
        "extra_asus_dial_use_dualsim",
        "com.android.phone.extra.slot",
        "slot",
        "simslot",
        "sim_slot",
        "subscription",
        "Subscription",
        "phone",
        "com.android.phone.DialingMode",
        "simSlot",
        "slot_id",
        "simId",
        "simnum",
        "phone_type",
        "slotId",
        "slotIdx"
};

for (String item :
        array) {
    Log.i(TAG, "Sim Card - " + item + " -----> " + intent.getExtras().getInt(item));
}

The output is always returns 0

Some articles shows it's not possible. But TrueCaller shows the target simcard for all incomming calls in all android mobiles.

I want to know solution like this

I tried so many ways nothing helps. Any help will be highly appriciated. Thanks in advance

You can try doing this inside your BroadcastReceiver class,

    public class IncomingCallInterceptor extends BroadcastReceiver {
     @Override
    public void onReceive(Context context, Intent intent) {

    String callingSIM = "";
    Bundle bundle = intent.getExtras();
    callingSIM =String.valueOf(bundle.getInt("simId", -1));

    if(callingSIM == "0"){
        // Incoming call from SIM1
    }
    else if(callingSIM =="1"){
        // Incoming call from SIM2
    }
    }

did you clearly read my question bro – Anand Apr 25 '23 at 06:55
this is not working – Anand Apr 25 '23 at 06:55
My apologies. I hope you came across [this](https://stackoverflow.com/a/59831344/14577209) answer. However, the SIM card data could be retrieved from `TelecomManager` class according to [this](https://stackoverflow.com/a/71986007/14577209). But I doubt whether if it is real-time or after receiving the call. Let me know how it goes! – Maleesha97 Apr 25 '23 at 07:27
yes bro , by usin the method we can get it after receiving the call – Anand Apr 25 '23 at 09:24
can you help to solv the issue – Anand Apr 25 '23 at 09:24
I trapped almost 3 days – Anand Apr 25 '23 at 09:24
Did you try it out? Do you need it when the call is coming in real time? not after receiving the call? – Maleesha97 Apr 25 '23 at 09:36
yes bro , I need it on real time – Anand Apr 25 '23 at 09:38
like truecaller showing in the popup – Anand Apr 25 '23 at 09:38
It seems like it is not possible to make it work on all devices but depends on the android version. Which Android version are you trying out the solution for? – Maleesha97 Apr 25 '23 at 09:44
Im trying on android 11, 12,13 not works – Anand Apr 25 '23 at 09:45
but how true caller did – Anand Apr 25 '23 at 09:46
If you find any solution let me know bro – Anand Apr 25 '23 at 09:54
I will try to provide you another solution as a new answer. Give me sometime. Give it a try. – Maleesha97 Apr 25 '23 at 09:58

You can try the following solution for this using SubscriptionInfo class.

But this works only when the phone number is associated with the SIM card.

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
 SubscriptionManager subscriptionManager = SubscriptionManager.from(getApplicationContext());

 // Create a PhoneStateListener to detect incoming calls
 PhoneStateListener phoneStateListener = new PhoneStateListener() {
     @Override
     public void onCallStateChanged(int state, String phoneNumber) {
         if (state == TelephonyManager.CALL_STATE_RINGING) {
             // Retrieve the list of active subscriptions
             List<SubscriptionInfo> subscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();
             if (subscriptionInfoList != null) {
                 // Loop through the list of active subscriptions
                 for (SubscriptionInfo subscriptionInfo : subscriptionInfoList) {
                     // Retrieve the phone number of the SIM card
                     String simPhoneNumber = telephonyManager.getLine1Number(subscriptionInfo.getSubscriptionId());
                     if (simPhoneNumber != null && simPhoneNumber.equals(phoneNumber)) {
                         // The incoming call belongs to this SIM card
                         int simSlotIndex = subscriptionInfo.getSimSlotIndex();
                         Log.d(TAG, "Incoming call belongs to SIM card in slot " + simSlotIndex);
                         break;
                     }
                 }
             }
         }
     }
 };

Register the PhoneStateListener,

telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

Nope. This is what I could find and implement. It should work on latest versions. It's highly depending on various factors such as Sim card association with the phone number, SIM cannot have multiple numbers and such. — Maleesha97, Apr 26 '23 at 16:42
Yes. its possible. you can use `telephonyManager.getSimSerialNumber();` to obtain it from above code. make sure you have READ_PHONE_STATE permission given first. — Maleesha97, Apr 27 '23 at 08:14
