Features:

The device contains not only the cellular antenna but also about 22MB (10MB on older versions) of storage memory accessible to the operating system as a USB mass storage device formatted with CDFS, thus emulating a CD-ROM drive. In this memory, E220 devices supplied by mobile operators may contain 3G dialer software written by the operator, while Huawei-branded devices contain Huawei's original firmware. Huawei's firmware and updates for it are also available for flashing from Huawei's website, or the firmware for 7.2 Mbit/s from the URL we provided in Email.( In reality "flashing" this device means writing a firmware image to its internal flash memory). Flashing the firmware of this device doesn't change the memory used for their operator's software, therefore connection settings (such as APN) will be retained. The software loaded on the device may start automatically through Windows's autostart facility, which can be bypassed by pressing the Shift key while inserting the USB cable of E220.

E220 connects to the computer with a standard Mini USB cable. The device comes with two cables, one short and one long. The long one has two USB A interfaces, one used for data and power and the other optionally only for assistance power in case the computer is not able to provide the full 500 mA (milliamperes) required for the device to work from one USB interface only. If your connection gets disrupted often or isn't really stable, consider using the two plug usb cable and supplying secondary power.

The E220 antenna is internal; the USB cable does not act as an antenna. There is a way to connect an external antenna even though there is no antenna connector. Together with a high gain antenna like an LPDA or an OMNI booster antenna and an adapter, signal strength can be considerably improved. There is also a way to open the modem, remove the small internal antenna, and solder a umts-antenna cable onto the board. You will invalidate the guarantee, but it can be a cheap and functional way to connect an external antenna.
