How to detect someone's sim card is active or not

Question

I have daily 40 to 50 phone numbers. Currently we are manually calling to each to detect each one's status like phone number is active(if call ringing) or not.I want to do this programmatically. Is it possible, to programmatically call each number and if phone ring is going on then set it's status active otherwise deactive?

Answer 1

Yes it is possible but better to use sms Delivery Report to check in android u may create a program in which if it shows delivery report than automatically added to active otherwise inactive

BroadcastReceiver sendBroadcastReceiver = new sentReceiver();
    BroadcastReceiver deliveryBroadcastReciever = new deliverReceiver();;

    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();

        try {
            unregisterReceiver(sendBroadcastReceiver);
            unregisterReceiver(deliveryBroadcastReciever);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    try {
        unregisterReceiver(sendBroadcastReceiver);
        unregisterReceiver(deliveryBroadcastReciever);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

    send_sms.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                if (textView.getText().toString().equals("")
                        | textView.getText().toString().equals(null)) {
                    Toast.makeText(SendSMS.this, enter_ph_no, Toast.LENGTH_LONG)
                            .show();
                } else {


                        sendSMS(textView.getText().toString(), "sms_content");
                        finish();


                }

            }
        });
private void sendSMS(String phoneNumber, String message) {
        String SENT = "SMS_SENT";

        PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(
                SENT), 0);

        PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
                new Intent(DELIVERED), 0);

        registerReceiver(sendBroadcastReceiver, new IntentFilter(SENT));

        registerReceiver(deliveryBroadcastReciever, new IntentFilter(DELIVERED));
        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);


    }
