One problem I have is I never receive notification of SIM insertion, i.e. the Present propertyChanged.  Looking at the code it seems pretty obvious why, unless I'm (probably) missing something.

Everything is working as it should, what exactly is the problem?  You 
can call ofono_sim_inserted_notify before the atom is registered, but 
that means the Present property will be 'True' when you perform the 
initial GetProperties call.

This is meant for devices which do not support SIM hot-swap (e.g. most 
USB devices and many earlier phones where the SIM is behind the battery).
