The EC25-J model is unable to use USSD codes, such as *100#, with the Quectel USSD command.

After executing the command quectel ussd quectel0 *100#, the dongle hangs and is unable to make calls.

The CLI output indicates an error during USSD transmission:

*CLI> quectel ussd quectel0 *100#
[quectel0] USSD queued for send
    -- [quectel0] Error sending USSD 0x5baf1dbc0d60

Hi,@mewaj78948
Could you tell me you current firmware version? It may be because the USSD function is not supported.
