Using the Huawei E220 under Linux is not supported by the 3G operator 3 (in SL). Here’s a guide how to get it working on Ubuntu.
Your connection have a pin-code per default set. Its written on your larger sim-card adapter. In order to simplify alot, lets just remove this. Put the 3g data simcard in your 3g-phone and remove the sim pin. Then put the card into the USB-modem.
If you start up your Ubuntu machine and plug in the USB-modem, it will show as a cd-rom drive (atleast my does). Also I’m getting a folder popping up as if it would be a storage device (it does seems to be a storage device for windows drivers..).
- First step, right click on the newly auto-created cd-rom icon on your desktop and choose eject. Close any windows using the device.
- Start a terminal. The commands below should be ran as root.
rmmod usb-storage
rmmod usbserial
(the later might create an error.)
lsusb
- The last command shoul show the device connected similiar to:
Bus 001 Device 003: ID 12d1:1003
Run:
modprobe usbserial vendor=0×12d1 product=0×1003
Now, disconnect the Huawei E220 USB-modem and wait a few seconds before connecting it again.
- As soon as the device have stopped blinking green you should find three new USB-devices by running the command:
ls -al /dev/ttyU*
Now you can see the Device in connection settings for Mobile Broadband
