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.

How to stop ofono forcing default at+cgdcont?
by JH
Hi,
What is the default setting in ofono for at+cgdcont?
+CGDCONT: 1,"IPV4V6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
I tried to add APN, every time I changed at+cgdcont, it reversed back
to 1,"IPV4V6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0 by ofono?
That is weird, please advise how to fix it.
Thank you.
Kind regards,
