You're missing the steps between install nm/mm packages and "Expected result".
E.g.
1. Created a new NM connection via "Edit Connections : Mobile Broadband tab - entered the following values..."
2. Selected new connection from the NM applet menu
3. Applet icon started spining, eventually went back to disconnected icon
4. etc...
