That (mmcli) will only be available in ModemManager >= 1.x, BTW. And
beware of --set-logging=debug, as syslog may limit those if MM sends
too many too fast. In general I usually prefer to ask for --debug
output just in case:
http://www.freedesktop.org/wiki/Software/ModemManager/Debugging/

I saw the reporter talk about Ubuntu Precise (12.04) and Trusty
(14.04), so only in the latter mmcli will be available (if I'm not
mistaken). For Precise, this Ubuntu page shows how to enable debug
logs:
