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
