public class SplahActivity extends AppCompatActivity {

    private Context context;
    private SubscriptionManager mSubscriptionManager;

    public static boolean isMultiSimEnabled = false;
    public static String defaultSimName;

    public static List<SubscriptionInfo> subInfoList;
    public static ArrayList<String> Numbers;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        context = this;
        setContentView(R.layout.activity_splah);

        Numbers = new ArrayList<String>();
        mSubscriptionManager = SubscriptionManager.from(context);
        GetCarriorsInformation();

    }

    private void GetCarriorsInformation() {
        subInfoList = mSubscriptionManager.getActiveSubscriptionInfoList();
        if (subInfoList.size() > 1) {
            isMultiSimEnabled = true;
        }
        for (SubscriptionInfo subscriptionInfo : subInfoList) {
            Numbers.add(subscriptionInfo.getNumber());
        }
    }
