Comment 3 for bug 212980

Here is a workaround to at least get it working:

1. Open a terminal and run: cd ~ && wget http://utils.eurion.net/hosted/huaweiAktBbo-i386.out && sudo mv huaweiAktBbo-i386.out /usr/local/etc/huaweiAktBbo-i386.out && sudo chmod +x /usr/local/etc/huaweiAktBbo-i386.out && sudo cp /etc/wvdial.conf /etc/wvdial.conf.backup

2. Run gksudo gedit /etc/wvdial.conf (either in a terminal or in the window that pops up when you press Alt + F2; if you are on KDE replace "gedit" with "kate") and write there the following text (without the -------- lines):

---------------------------------------------------------------------------------------------------------------------
[Dialer Defaults]
Phone = *99***1#
Username = vodafone
Password = vodafone
Stupid Mode = 1
Dial Command = ATDT

[Dialer hsdpa]
Modem = /dev/ttyUSB0
BAUD = 460800
Init2 = ATZ
Init3 = ATE0V1&D2&C1S0=0+IFC=2,2
ISDN = 0
Modem Type = Analog Modem
Init5 = AT+CGDCONT=1, “IP”, “ac.vodafone.es”
---------------------------------------------------------------------------------------------------------------------

You will have to change the value of Username, Password, Init5 (and perhaps Phone, too), depending on what provider you use. For example, if you are with Movistar you will find the necessary stuff in the first comment in http://bloc.eurion.net/archives/2007/vodafone-mobile-connect-3g-ubuntu/.

3. Again in the terminal, run: sudo touch /usr/local/bin/connect && sudo chmod +x /usr/local/bin/connect && sudo gedit /usr/local/bin/connect and write the following code into the file:

#/bin/sh
echo ""
sudo modprobe usbserial vendor=0x12d1 product=0x1003
echo "Executed modprobe..."
sleep 5
echo ""
sudo /usr/local/etc/huaweiAktBbo-i386.out
sleep 5
echo ""
sudo wvdial hsdpa

4. That's it. Now, running connect each time you want to go online should be enough (remember that some times if it doesn't work it might be necessary to pull the modem out, wait for 10 seconds, put it back in, wait 10 seconds more, and try again running "connect" once or twice).
