Yes, but that is not what you outlined in the code.  You were watching 
for SIM_STATE_READY which only means just that.

Also note that we can bring the modem online even in pre_sim state (e.g. 
for emergency calls), in which case the lte atom doesn't exist yet.

I don't see what set_property is buying you.  Anyway, feel free to come 
up with a more detailed proposal, but my impression is that this 
approach will quickly become way too complicated.
