Comment 30 for bug 414604

I have had the same problem with Novatel MC950D 1410:4400.
After updating the system with networkmanager from trunk ppa and with not realesed updated (2.6.31-15-generic-pae)
the problem have not dissapeared.
Following the instructions in https://wiki.ubuntu.com/DebuggingModemmanager I noticed that the call number was *99***1#***1#
instead of what I have inserted in knetworkmanager config (*99***1#), I changed the number to *99#, and now it works.
I have had also problems with usb-switch, following this instructions "http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=247&view=next&sid=4e40a70b2235b2e73caaa95451ca898b" now it works. In kubuntu 9.10 the problem seems to be /lib/udev/rules.d/61-modem-switch.rules file.
