That shouldn't really happen. If operator wants to show you something like
this, that comes as a response to your USSD comand request either as a
clear response or a text message.

I think those should be MMI commands not USSD ones. MMI commands are
executed immediately when the command parser recognizes the command, and
are not sent out to the network. They look pretty similar to USSD ones,
however they have this tiny exception.

So, do I get it right, that operator/oem specific MMI commands (not USSD)
can be provided through some plugin system?

If the previous question of mine is valid, i.e. operators/oems can provide
their MMI command interpreters, then I think that's more or less we need to
have.
