I believe this was a bug in ModemManager that Alexander Sack just fixed.
ModemManager should not be running the CFUN commands on Nokia phones,
since CFUN=0 makes the phone shut off.  The MM enable sequence calls
CFUN=1, which the nokia phones do not support (so much for standards)
and an error is returned, then when NM directs MM to clean up the
connection attempt, MM runs CFUN=0 which makes the phone shut down.

Look for an update in 9.10 soon.
