I found a workaround. I have installed the package "comgt". If I plug in the modem, let it settle, then run comgt in a command line, it asks for the PIN and it registers in the network (also switches the LED from red to blue) then if i restart networmanager (and wait for ~30seconds) I can enable the mobile broadband and connect using the network manager applet.

Registered on Home network: Failed to register smiki@smiki-AOD257:/var/log$ sudo /etc/init.d/modemmanager restart Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service modemmanager restart Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the stop(8) and then start(8) utilities, e.g. stop modemmanager ; start modemmanager. The restart(8) utility is also available. modemmanager stop/waiting modemmanager start/running, process 11425 smiki@smiki-AOD257:/var/log$ syslog output after modemmanager restart (the comgt does not spit out anything to the logs): Jan 4 20:40:41 smiki-AOD257 modem-manager[11327]: <info> Caught signal 15, shutting down...
