I want to get sms delivery report with my own windows application by using AT commands.

but when i send my sms i just get the ok message how can i do this? what command i should send after sms sending to my network?

I have a Nokia 6630 phone and D-LinkDWM156 GSM modem and Huawei E171 GSM Modem. i installed all of them on my pc with their original windows applications and it's very interesting to me why all of theme have not delivery report for sent SMS(text message).

when you sent a sms from their own applications there is no place to find that sms has been delivered or not, WHY?

to send sms

AT
AT+CMGF=0
AT+CMGS= + (sendData.Length / 2 - 1).ToString() //just to show

after sending i got this

+CMGS: 35   //i think it's sms index number on sim

to get report i send

"AT+CNMI=2,1,2,2,0"

and got "ok" and nothing else
