Huawei E220

Technically it is a modem, USB and (due to the ISO 9660 format) virtual CD-ROM device.

Launched on 21 June 2006,[1] the device is used for wireless Internet access using 3.5G, 3G, or 2G mobile telephony networks.

Huawei's Dashboard and updates for it are also available from Huawei's website,[10] or the 11.313.02.00.01 firmware for 7.2 Mbit/s from NetCom (in reality 'flashing' this device means writing a firmware image to its internal flash memory, which is different from "updating the dashboard", which is simply writing a new ISO 9660 disc image to the USB mass storage device that appears in the operating system).

Flashing the firmware of this device doesn't change the USB Mass Storage memory used for the operator's software, therefore connection settings (such as APN) will be retained.

It is possible to remove the operator branding by flashing the device with Huawei's Mobile Partner software.

If the connection is frequently disrupted or is unstable (or usable at slow speeds only), the two plug USB cable should be used instead.

Since the release of Windows 7 users have reported a number of issues that require a firmware upgrade to the modem.
