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?
your module is registred to network?
What is the result of AT+CREG? and AT+CSQ
I have tried on multiple networks & RATs with different SIM cards.
Yes the SIM is registered and I can make calls.
Thanks for any help
which FW version are you using?
I checked the FW version with my supplier and have a new version so it now works fine.
