MNC and MCC of a secondary SIM

问题

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.

        List<SubscriptionInfo> subscriptionInfoList=new ArrayList<>();
        subscriptionInfoList=subManager.getActiveSubscriptionInfoList();
