Hi Dan,

# nmcli con show eth0
Error: eth0 - no such connection profile.

Not sure of what you are talking about.  I am pretty certain that eth0 
is the real device interface.

# nmcli d
DEVICE   TYPE      STATE      CONNECTION
eth0     ethernet  connected  Wired connection 1
ttyACM0  gsm       connected  gsm1
ppp0     unknown   connected  ppp0
lo       loopback  unmanaged  --
sit0     sit       unmanaged  --
wlan0    wifi      unmanaged  --

The configuration is mostly the default one, just unmanage the WiFi and 
configure the GSM APN.

# cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

[keyfile]
unmanaged-devices=mac:00:0b:6c:41:eb:24

# cat /etc/NetworkManager/system-connections/gsm1
