Don't know about USSD - of course you can try 

dbus-send --system --type=method_call --print-reply=True \
 --dest=com.nokia.csd.SS /com/nokia/csd/ss \
   com.nokia.csd.SS.USSD.Command string:'*#21**89#' string:

and see what you get for response.

Call-UI does not recognize the non-standard basic service number (89)
used for ALS, so you can not enter the code directly on call ui.

The modem does not support ALS line 2, it would have required special
modem firmware. With the current modem firware, you can only divert line
2 calls to line 1.
