No, the HE910 supports CFUN modes 0,1,4,5,7 where:
1: online
4: offline (airplane) mode with SIM powered off
0,5,7: online w/ power saving modes; SMS and phone calls are active in
these modes, but AT command handling seems to be turned off

See Telit Modules Software User Guide, 1vv0300784 rev 11, 2012-09-20,
section 3.6 (page 105) for a description of these modes.

OK, I need to check what CFUN mode we need in order to be able to make
emergency calls.  I think 4 won't work... CFUN=4 is really 'airplane
mode' with antennas off.

My interpretation of modem 'enabled' in ofono is that it's 'airplane
mode'... is this not correct?
