Hi Neil,

You will most likely need to install some additional package into
whatever distro you're thinking of and will almost certainly need to
change the USB vendor ID (-v 0x12d1) and USB product ID (-p 0x1446) to
match the dongle in question.

/lib/udev/modem-modeswitch -v 0x12d1 -p 0x1446 -t option-zerocd

After issuing this Linux would seem to re-probe the specific USB device
ignoring anything that looks like a CD drive, and so finding the USB
serial port.

After it has found the serial port, you can treat it just like any
other serial modem.  I used to use wvdial when connecting to t'Internet
via my Nokia N95 in modem mode.

Your wvdial.conf might need to look something like this:

[Dialer Defaults]
Init1=ATZ
Init2=ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3=AT+CGDCONT=1,"IP","three.co.uk","",0,0
Baud=460800
Modem Type=Analog Modem
ISDN=0
Phone = *99#
Username = user
Password = passwd
New PPPD = yes

[Dialer Dongle0]
modem=/dev/ttyUSB0

Changing the entries in the Init3 line to match your mobile provider's
specs.  Google is your friend here.

Once this is in place, you should be able to initiate a PPP connection
by issuing:
# wvdial Dongle0

Hope this helps.
Grant. :)
