i used windows hypertrminal to send USSD commands by my New  GSM Modem:
D-LINK DWM-156 HW ver:A7 and F/W ver:7.0.1.ME.

i send AT and retrive OK

Send: AT+CUSD=1,"*100#",15

i just receive "AT+CUSD=1,\"*100*1#\"\r\n\OK\r\n" and not another message in hyper terminal windows.

i go to check these commands with another modem and my phone and they returned operator message but i can not retrieve operator message on this model of modem what is wrong with me?
please guide me

i send these command with modems own windows application and it works fine and i found that this model of modem may be have special command before or after sending USSD commands

I'm confuse because this is the simple command and it should works.

You'll need to phone contact your regional D-Link support office and ask about this.
