Dear Oren,

Please read chapter 10.8 of the included Quectel_BG96_AT_Commands_Manual_V2.3.pdf
Quectel_BG96_AT_Commands_Manual_V2.3.pdf (1.5 MB)

Good luck ;o)

Thank you very much Leonardus,

I saw the AT+CUSD command and still failed to execute it.

It seems like the BG96 doesn’t support this command …
According to Stephen the BG96 doesn’t support AT+CUSD command.

Dear Oren, After asking with R&D, indeed BG96 can not support USSD.
The command AT+CUSD will be removed from the AT manual.
The reason is that USSD uses 2G CS (Circuit Switched)，but the BG96 has no CS domain, only PS (Packet Switch) domain.
