How to check for the delivery report of the sent message. I am using PHP and I have the smpp account. Can somebody help me with the checking of delivery report. Will I get an delivery report as message like we get in our mobile. Or the status of the send function will do for it?
Answer
Using SMPP you can retrieve delivery report in the following ways.
First choice is to set registered_delivery parameter to 1 when you send submit_sm PDU. This case SMSC should send you deliver_sm PDU with esm_class = 0x04 containing delivery report.
Other way is to request delivery status with query_sm command but this may generate more traffic if polling SMSC too often.
