E220 should work with NetworkManager (ModemManager). In order to found the 
issue, please provide more information on what are the symptoms, how you 
configure the connection, etc.

What NetworkManager and ModemManager versions do  you use?
What lsusb says about the modom?
What's in /var/log/daemon.log?

You can follow the steps at [1] in 'Debugging NetworkManager 0.8.x 3G 
connections' section to get detailed traces.

For a reference, you can look at [2].
