You need to tell us what modem it is (brand, model). Anyway Mitch was right on the link, although today, things are a bit easier.

For telling model of modem, on a console:

sudo lsusb

Method 1

  1. Take a look at the output of lsusb. You should see your modem assigned to ttyUSB* ports:

    sudo ls /dev/ttyUSB*

    ttyUSB0 - Should be the modem
    ttyUSB1 - Should be the USB module

  2. Download a dialer

    sudo apt-get install wvdial ppp
  3. Configure your connection

    gksudo gedit /etc/wvdial.conf

    and use something like the following:

    [Dialer hsdpa]
    Phone = *99***1#
    Username = vodafone
    Password = vodafone
    Stupid Mode = 1
    Dial Command = ATDT
    Modem = /dev/ttyUSB0
    Baud = 460800
    Init2 = ATZ
    Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
    ISDN = 0
    Modem Type = Analog Modem

    You need to set your Phone number, username and password, these are values given by your operator.

    Also set the connection on Modem (/dev/ttyUSB0)

    The name hsdpa, is generic, you can use whatever name you want.

When dialing your connection, is this name you use.

If using PIN code add this before Init2

    Init1 = AT+CPIN=9999

where 9999 is changed for your PIN-code

  1. Start your connection

    sudo wvdial hsdpa

hsdpa is the example name i've used, you have to use the one you choosed in wvdial.conf
