MNC and MCC of a secondary SIM

Question

I know that using TelephonyManager we can get MNC and MCC of our network provider,

TelephonyManager tel = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String networkOperator = tel.getNetworkOperator();

if (networkOperator != null) {
    int mcc = Integer.parseInt(networkOperator.substring(0, 3));
    int mnc = Integer.parseInt(networkOperator.substring(3));
}

But I was able to get MNC and MCC data of only primary sim. I would like to know is there a way to fetch mnc,mcc,lac and cellid's of Secondary sim of a device in android.

Before API 22, it will be hard to achieve what you want.

I believe that before API 22, dual SIM was not originally supported by Android. So, each Mobile vendor should have its own implementation. Maybe, you should get their APIs/SDKs and include them to your project. Only this way, you will have access to their APIs.

From API22 onward, I think you can use SubscriptionManager

    int mccSlot1 = -1;
    int mccSlot2 = -1;
    int mncSlot1 = -1;
    int mncSlot2 = -1;

    SubscriptionManager subManager = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);

    if(subManager.getActiveSubscriptionInfoCount() >= 1) {
        mccSlot1 = subManager.getActiveSubscriptionInfo(0).getMcc();
        mncSlot1 = subManager.getActiveSubscriptionInfo(0).getMnc();
    }

    if(subManager.getActiveSubscriptionInfoCount() >= 2) {
        mccSlot2 = subManager.getActiveSubscriptionInfo(1).getMcc();
        mncSlot2 = subManager.getActiveSubscriptionInfo(1).getMnc();
    }

Question https://stackoverflow.com/a/32871156/4860513 mention the same Android Limitation. So, I really believe it is not possible to achieve that before API22 with pure Android SDK.

Sometimes SubscriptionManager gives the same values for both SIMs. Some other times, it gives wrong values even when only one SIM is installed. That makes it unreliable to use. I am testing against Android 5.1 on a Motorola Moto E device. – Beshoy Fayez Apr 29 '16 at 00:57
@BeshoyFayez Yes i also face same issue when i check this api to ViVo v5 mobile get same value for both sim. if you find any other code to get value of mcc/mnc please put here – Chirag Parmar Dec 29 '17 at 10:10
I have android 6.0.1 face same problem this api give same mcc and mnc for both different operator(One is Airtel and other is Vodafone) sim – Ashish Garg Jan 16 '18 at 11:48
this method returning null. I am testing against android 8.0 Nokia3 – Uzair Qaiser Jul 04 '18 at 06:46
The subId is not alway 0 or 1. SubscriptionManager.getDefaultSubscriptionId() returns 6 in my phone. – James Feng Jun 20 '20 at 04:20
MCC number would be the same for both SIM (Bcz this Country Code), MNC could be different depends on operator type. More detail: https://www.mcc-mnc.com/ – Satwinder Singh Jun 07 '21 at 07:41

        SubscriptionManager subManager = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
        List<SubscriptionInfo> subscriptionInfoList=new ArrayList<>();
        subscriptionInfoList=subManager.getActiveSubscriptionInfoList();
        Log.d("LIST LIST",subscriptionInfoList.toString());

The Log was
