Correct.

See oFono documentation on Connection Context.

/*
  * The way this plugin works is following:
  *
  *   powered -> SubscriberIdentity or Online = True -> gprs, context ->
  *     attached -> netreg -> ready
  *
  * Depending on the modem type, this plugin will behave differently.
  *
  * GSM working flow:
  *
  * When a new modem appears, the plugin always powers it up. This
  * allows the plugin to create a connman_device. The core will call
  * modem_enable() if the technology is enabled. modem_enable() will
  * then set the modem online. If the technology is disabled then
  * modem_disable() will just set the modem offline. The modem is
  * always kept powered all the time.
  *
  * After setting the modem online the plugin waits for the
  * ConnectionManager and ConnectionContext to appear. When the context
  * signals that it is attached and the NetworkRegistration interface
  * appears, a new Service will be created and registered at the core.
  *
  * When asked to connect to the network (network_connect()) the plugin
  * will set the Active property on the context. If this operation is
  * successful the modem is connected to the network. oFono will inform
  * the plugin about IP configuration through the updating the context's
  * properties.

I have only a vague memory on this topic, but I think to remember that 
oFono will only show the CM if the APN was provisioned in oFono. Maybe I 
have false memory on it.

Thanks,
Daniel
