ConnectionManager is created by the ofono_gprs atom.  This atom can be 
created either in post_sim or post_online state.

The earlier state is preferred (e.g. post_sim), but some hardware 
implementations might want to delay this until post_online for whatever 
reason.  I think the majority of oFono modem drivers initialize 
ofono_gprs in the post_sim state.

Note that the functionality of ConnectionManager will be largely 
unavailable without network registration.  So you won't be able to 
activate / deactivate contexts until you are registered to the network. 
  You can however manipulate context settings and other settings (e.g. 
in Airplane mode or without being registered to a network)
