Answer 1

Hi,

You should use another AT command to send USSD commands. Its AT+CUSD=1,<ussd_command>,15

 Unfortunately this command return OK to any command you send. After the operator response to command module get unsolicited message which you can't see using gsmctl.

Thanks. returns Ok. How can I read the answer from the operator?
