Meanwhile, on Ubuntu 16.04 and with network-manager 1.2.2-0ubuntu0.16.04.3, from my side I have no longer the described issues. Both ModemManager, NetworkManager and nm-applet are working flawlessly.

Regularly (if not always) the nm-applet icon is not showing in the Unity panel after logon. Syslog shows these error messages: Jan 23 21:07:21 desk1 gnome-session[3904]: (nm-applet:4812): nm-applet-WARNING **: Could not find ShellVersion property on org.gnome.Shell after 5 tries Jan 24 09:42:37 desk1 gnome-session[19922]: (nm-applet:20700): libnm-glib-WARNING **: Error in get_property: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist Jan 24 09:42:38 desk1 gnome-session[19922]: (nm-applet:20700): nm-applet-WARNING **: Cannot grab information for modem at /org/freedesktop/ModemManager1/Modem/0: No ModemManager support Jan 24 09:42:38 desk1 gnome-session[19922]: (nm-applet:20700): nm-applet-WARNING **: ModemManager is not available for modem at /org/freedesktop/ModemManager1/Modem/0 Jan 24 09:42:38 desk1 gnome-session[19922]: message repeated 3 times: [ (nm-applet:20700): nm-applet-WARNING **: ModemManager is not available for modem at /org/freedesktop/ModemManager1/Modem/0] Jan 24 09:42:38 desk1 gnome-session[19922]: nm-applet:ERROR:applet-device-broadband.c:644:get_icon: assertion failed: (info) Manually starting nm-applet from a Terminal works, sometimes however only after some attempts where error messages similar to the ones above are shown (btw, even when succeeding, the first 2 warning/error messages on the ss signature and the ShellVersion show up). Once nm- applet is started, the 3G modem connection signal bars are shown and sometimes indeed a network connection (through 3G modem) is available. Often however, several manual disconnect and subsequent connect operations are needed before having the network connection really up and running. I suspect hence that there is an issue with my ModemManager and/or NetworkManager configuration or implementation, and that nm-applet is not robust enough to properly deal with these connection failures. I have no issues on another Ubuntu 15.10 system with the same version of network-manager installed.
