No USSD responses

IoT Modules MC/EM Series
1

Hi,

I am trying to send a USSD message using my MC7304.

I have tried lots of variations of AT+CUSD and I always receive “OK” but no network (or device) response.

Is it really supported by the device or is there some command I need to give to directly read the USSD?

thanks
