5.4 Enquire message status (04)
CIMD Interface Specification
This operation is used to request a status report for a previously submitted
message.
An enquire message status operation can be performed independently of the
status report request parameter used in the submit message operation. However,
a returned status code usually indicates that the status is unknown, because the
SMS Center will not keep track of statuses unless requested at submission time
for performance reasons.
No multiple enquiries are allowed in one enquire message status message packet,
so SMEs have to request each status report separately.
Note that, because of the nature of USSD, a USSD Center connection will always
return a negative response packet.
