get mesage ID without DLR

[Gustavo Mohme C.]

Hi All,
I am currently using mask=31. Nevertheless, it is generating unnecessary
traffic since I am only interested in getting the message_id from the
submit_sm_resp. Is there a way to get the message_id without using mask=#?
 The reason I only need to get the message_id is because, after the id is
stored, I use query_sm to check the status(SMSC doesn't support DLR) of the
message. What would be the simplest mask value that would get this job
done(mask=1 maybe?).
Thanks a lot!
Gustavo
