gsm - how to config CNMI to receive delivary message? -

i have d-link gsm modem (dwm-156) , want config cnmi receive delivery reports after sending text message.

the support cnmi mode on modem returns:

+cnmi: (0-3), (0-3), (0,2,3), (0,1), (0,1) 

the default mode returns:

+cnmi: 2, 1, 0, 0, 1 

when send message not receive delivery report.

i tried changing cnmi to

        2, 1, 2, 1, 0 

but sim card , d-link modem storage still have not stored messages.

this process has worked on (huawei) modem had cnmi:

"at+cnmi=2,1,2,2,0"
