EG06-E USSD not replying

Hello everyone! I am trying to send a request for a USSD, sending occurs, an OK response comes, but I do not receive an informational response. What am I doing wrong?
Found on the forum a topic that BG96 does not support USSD, but what about EG06?

tty_data_handler:240: AT+CUSD=1,*201#,15

Thanks for your query in Quectel forums.
EG06-A and EG06-AUTL support USSD, but EG06-E does not support USSD, BG96 only supports BG96MAR04A02M1G_01.002.01.002 this version supports USSD,thanks.

Thanks for the answer!

Tell me please about EP06-E support USSD? I have the same thing as the topic starter, in response, OK and silence…

Thanks for your query in Quectel forums.
Unfortunately, EP06 does not support USSD,thanks.
