Get SimOperatorName for Dual SIM Phone

Get operator Sim name for dual SIM phone.

I am working on an application where I need the details of a custom SIM for its operator name. How to get his number both SIM and operator name for both connections.

This is my code ...

    private static String getOutput(Context context, String methodName,  int slotId) {


    TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

    Class<?> telephonyClass;
    String reflectionMethod = null;
    String output = null;
    try {
        telephonyClass = Class.forName(telephony.getClass().getName());
        for (Method method : telephonyClass.getMethods()) {
            String name = method.getName();
            if (name.contains(methodName)) {
                Class<?>[] params = method.getParameterTypes();
                if (params.length == 1 && params[0].getName().equals("int")) {
                    reflectionMethod = name;
                }
            }
        }
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    if (reflectionMethod != null) {
        try {
            output = getOpByReflection(telephony, reflectionMethod, slotId, false);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    return output;
}

private static String getOpByReflection(TelephonyManager telephony, String predictedMethodName, int slotID, boolean isPrivate) {

    //Log.i("Reflection", "Method: " + predictedMethodName+" "+slotID);
    String result = null;

    try {

        Class<?> telephonyClass = Class.forName(telephony.getClass().getName());

        Class<?>[] parameter = new Class[1];
        parameter[0] = int.class;
        Method getSimID;
        if (slotID != -1) {
            if (isPrivate) {
                getSimID = telephonyClass.getDeclaredMethod(predictedMethodName, parameter);
            } else {
                getSimID = telephonyClass.getMethod(predictedMethodName, parameter);
            }
        } else {
            if (isPrivate) {
                getSimID = telephonyClass.getDeclaredMethod(predictedMethodName);
            } else {
                getSimID = telephonyClass.getMethod(predictedMethodName);
            }
        }

        Object ob_phone;
        Object[] obParameter = new Object[1];
        obParameter[0] = slotID;
        if (getSimID != null) {
            if (slotID != -1) {
                ob_phone = getSimID.invoke(telephony, obParameter);
            } else {
                ob_phone = getSimID.invoke(telephony);
            }

            if (ob_phone != null) {
                result = ob_phone.toString();

            }
        }
    } catch (Exception e) {
        //e.printStackTrace();
        return null;
    }
    //Log.i("Reflection", "Result: " + result);
    return result;
}

      

        
        
        
      

    

to call the method is ...

  final String optName1 = getOutput(getApplicationContext(), "getSimOperatorName",0);
  final String optName2 = getOutput(getApplicationContext(), "getSimOperatorName",1);
