[Hilo] How to get SMS Delivery report? How to receive an acknowledgment after sending a SMS?
Answer: To enable the SMS Delivery report URC, you need to set <AT+CNMI=2,1,2,1,0> whatever SMS is PDU or TEXT mode.
Also, if in text mode, you need to enable the report feature by setting <AT+CSMP=49,167,0,0>… (Please make sure the report bit is 1. 49 = 110001(B))
If in PDP mode, you need to enable the report feature in the PDU field.
Be careful, AT+CSMP has an effect only on all NEW SMS sent or written into the SIM. All OLD SMS already stored in the SIM will not be impacted.
For example:

AT+CNMI=2,2,0,1,1 ----Set 1 to enable the URC of +CDS (status report)
OK

OK
AT+CSMP?
+CSMP: 17,167,0,0 ----The configuration of CSMP(Disable the status report) is ignored when sending PDU SMS.
