this is not correct.

Just leave "connection.interface-name" unspecified, for example via:

    $ nmcli connection modify NAME connection.interface-name ""


and check it with

    $ nmcli connection show NAME



Thanks Thomas for this trick.

I have redacted this /etc/NetworkManager/system-connections/gsm1 file:
--------------------------------------------------------------------
[connection]
id=gsm1
uuid=f5e7b733-beea-4fcb-b213-b2dfcbd61073
type=gsm
timestamp=1432623762

[gsm]
number=*99#
apn=<redacted>

[ipv6]
method=auto

[ipv4]
method=auto
--------------------------------------------------------------------
And it work as expected after a 'nmcli connection reload'.

For my curiosity, where this is documented ?

The meanings of the properties are documented in
  man nm-settings

On recent NM versions there is also
  man nm-settings-keyfile

(which has some further details when you edit the config-file directly).



You ~can~ edit the files by hand, followed by
  nmcli connection reload
or
  nmcli connection load /etc/NetworkManager/system-connections/gsm1


alternatively, you can use nmcli. See also `man nmcli` 
and `man nmcli-examples`.
