Why? The earlier firmware HE910 did not have a concept of 'Online'.
CFUN=1 triggered full functionality, while CFUN=4 disabled the SIM. So
for oFono's purposes, CFUN=4 was a powered down modem.
If the plugin does not provide .set_online, then oFono core assumes the
modem only supports Powered = False and { Powered = True, Online = True
}. { Powered = True, Online = False } mode is not possible to achieve.
I have no idea if ConnMan supports this setup.
I believe Telit made CFUN=4 only affect the TX/RX circuits in their
latest firmware, but my information might be a year or two out of date
and my memory may be faulty :)

No idea.
