and than you need to make a request for the below parameters in your page.

Message Id is the message id you may have got while submitting the sms via sendsms.php please note that this is not supported for bulksms.php or groupsms.php calls where sms are sent in bulk.
Once you are through you need to provide the callback page under the same link for us to push back the dlr in your system once we have the status in realtime in order to avoid loads on our server.
Hope this helps and you could request further information from the support team and your account manager on the guidelines.
