The following cards/phones works 100% with next scripts/configs:

  • Novatel Merlin U630
  • Option Fusion
  • Option Quad
  • Motorola E1000
  • Nokia 6680 (just don't set the speed/service - no 3gonly and 384k configs)
  • Option HSDPA Card
  • Novatel HSDPA Card
  • Huawei/E620
  • ["Huawei/E220"]



You need to download the new wvdial.conf for the HSDPA stuff to work !!!

This was originally written for Gentoo Linux which compiles everything from source. As a result of things might be a bit different, but we can work around it. Firstly, we need to get Linux to detect your card, start your PCMCIA services - normally this can be done using (most distros do this for you):

Before you insert your card, open a console/switch to an open console and as root run the following :

invoke-rc.d pcmciautils start

This will allow you to "see" what Linux is doing :

tail -f /var/log/messages 

Right, now insert your card and you should see some stuff happening. I have included log traces of what the two cards "look" like under /var/log/messages in the attachment section.

If you see only the inline:option_insert_nousb.txt messages using an option card run the following command:

modprobe usbserial vendor=0x0af0 product=0x5000

If you had to run the above command, you will need to save the attachment:vmc_g file attached into /etc/modules.d

Now we need to find out where your card is - you will see in the messages where the card is - /dev/ttyS? for novatel or /dev/ttyUSB? for option

find /dev/ | grep ttyS

Should show /dev/ttyS0 or /dev/ttyS1 for a Novatel Card.

find /dev/ | grep ttyUSB

Should show /dev/ttyUSB0 and USB1 and USB2 for an Option Card. (or /dev/tts/ttyUSB0-2 for udev)

Once we found that, we need to change /etc/wvdial.conf to match your settings, attached is my working attachment:wvdial.conf. Now we can start dialing up

For Novatel

wvdial novatel internet 3gonly 384k

For Option

wvdial option internet 3gonly 384k

If you need to send your PIN, add "pin" infront of all the commands, e.g.

wvdial pin novatel internet 3gonly 384k

Once your connection is up - surf away Now you can setup things like KPPP and Gnome's Modem Lights to do your dialing for you.

Extra Steps for the HSDPA card

Download the kernel module from the link below. Extract it to a directory somewhere safe.

Compile the driver using the following commands:

make clean && make

Once this is done, run the following command to insert the module into the kernel

insmod nozomi.ko

Once you have done that, use the following command to setup the connection:

wvdial hsdpa

Extra steps for the Novatel U740 Card

Until I get time to update the files etc. our Novatel Linux Users out there can just type this command before using the normal dialing command:

modprobe usbserial vendor=0x1410 product=0x1400


modprobe usbserial vendor=0x1410 product=0x1410

Using ["lsusb"] will show you the Vendor and Product ID's or cat /proc/bus/usb/devices will do the same.I will still add them into the FAQ but at least this should help for now

This will add the USB's like the 3G Option did - am I seeing a swap here ? - so just dial /dev/ttyUSB0 or so - check the logs

==Extra Steps for the Huawei Cards == None really - just make sure usbserial is loaded and the card will come up on /dev/ttyUSB0 - check the logs again to confirm

If the card doesn't come up, unload usbserial and reload with the following command:

rmmod usbserial
modprobe usbserial vendor=0x12d1 product=0x1001

I am still trying to work on the USB only card, so at the moment, I don't know if it will work under Linux.

Huawei E220

I have found that this modem will only work with the short cable supplied...not the long one with two plugs...*shrug*

Same as the E620, except use the following modprobe command:

rmmod usb-storage
modprobe usbserial vendor=0x12d1 product=0x1003

(Some have reported an ID of 0x1001 - use lsusb to confirm) After that, you will notice only one USB serial coming up, then, remove the device and re-attach it, you shouldn't need to re-insert usbserial.


I have only seen 3G speeds on this device, but I think it is because of my RF conditions and location. More on this to follow...




How do I enable "Internet Connection Sharing" ?

A) Since the 2.6 kernel is main stream etc. I will only cover IPTables and Kernel 2.6. I am also assuming that ppp0 is your dialup and eth0 is your lan. ?BR Firstly - we need to add some rules to iptables - run the following commands:

#This will CLEAR ALL RULES !!!
iptables -F 
#Enable NAT (through the ppp0 interface)
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

#then we need to enable routing:
echo "1" > /proc/sys/net/ipv4/ip_forward
That should do it - from here you can add rules to block incomming connections etc.
My card is broken/replies "ERROR" to all the commands
A) You didn't send your PIN to the card - either add the "pin" command or disable the PIN on the SIM
My Novatel card is very slow - +-800 bytes per second

A) Try running "setserial -a /dev/ttyS1 low_latency spd_warp" - replace /dev/ttyS1 with your port ?BR Once you have your setserial command, insert it into /etc/ppp/ip-up.local - this will cause the command to be ran everytime a connection is made.

What does all the wvdial sections do/mean ?
  • Defaults - What to do if nothing is selected (Always included)
  • pin - send your pin to the card
  • novatel - select the novatel card
  • option - select the option card
  • hsdpa - Option HSDPA card
  • e1000 - select the E1000 via USB
  • onboard - select the onboard modem of my notebook
  • internet - select the internet APN
  • internetvpn - select the internetvpn APN
  • myapn - select your apn
  • 384k,144k,64k - select the speed of your 3G connection
  • 2gonly - select GPRS only
  • 3gonly - select 3G only
  • How do I see the usage under Linux ?
    Linux Usage


    • Make the Option card call "modprobe usbserial" by itself
    • Make the Novatel card register the second port under Linux
    • Do some research into the signal levels reported via +CSQ
    • Get the PIN to work with wvdial and Novatel
