How are you intending to use the "sequence_number"?

I think you might be expecting functionality in SMPP which is not present.

The SMPP spec says:


quote:

This field contains a sequence number which allows SMPP requests and responses to be associated for correlation purposes. The use of sequence numbers for message correlation allows SMPP PDUs to be exchanged asynchronously.




However, this does not mean that you can submit a reply with message text back to that sequence number. The sequence number is only a protcol element ... it is used to acknowledge back to the SMSC that we received the message (no further reply is allowed).

The registered delivery flag can be set by submitting a message with the a parameter of "DeliveryReceipt=Yes" included in the HTTP request.
