Using Huawei E220 HSDPA modem in GNUNTU

E220 works perfectly with wvdial on ubuntu Hardy Haron.
Here are the steps…
(1) Plug in the modem and run
sudo wvdialconf
(2) Then edit the wvdial.conf file…
sudo vim /etc/wvdial.conf Uncomment Username and Password lines in wvdial.conf and add the following to the end of the file "stupid mode = yes"
(3) Save the wvdial.conf
(4) run wvdial to get connected :)

If you are using ubuntu 8.10 then the Graphical Network Manager recognizes the modem and connects you within seconds.
