Smsmanager class to know if you really sent the text

Question

I use the Smsmanager class to text in my app like this

smsManager.sendMultipartTextMessage (telefones.get(i), null, smsManager.divideMessage(men), enviados, entregues);

there’s this part of the code here that returns whether you can send it or not

context.registerReceiver(new BroadcastReceiver(){
    @Override
    public void onReceive(Context context, Intent arg1) {
        switch (getResultCode())
        {
            case Activity.RESULT_OK:
                j++;
                Toast.makeText(context, j + " SMSs enviados", 
                        Toast.LENGTH_SHORT).show();

                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                Toast.makeText(context, "Falha Geral", 
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                Toast.makeText(context, "Sem serviço", 
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                Toast.makeText(context, "Null PDU", 
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                Toast.makeText(context, "Radio desligado", 
                        Toast.LENGTH_SHORT).show();
                break;
        }
    }

}, new IntentFilter(SENT));

was wanting to pass the phones together with the sent Internet , someone knows how to do this?
