Chapter 1 Product Overview 

The HUAWEI E220 USB Modem is a terminal available for high-speed wireless 

network access, with which the users can access the Internet in the wireless way at 

home, office, outdoor sites and so on. It is designed in compliance with the 

HSDPA/UMTS (3GPP R99 & R5) and EDGE/GPRS (3GPP R99) specifications. It 

senses the signal strength of the HSDPA/UMTS and EDGE/GPRS network on a 

real-time basis, and allows users to choose the network freely. The HUAWEI E220 USB 

Modem delivers an access rate up to 3.6Mbps on the HSDPA, or 384kbps on the UMTS, 

or 236.8kbps on the EDGE, or 85.6kbps on the GPRS network. At the same time, it 

supports short message services. 

The HUAWEI E220 USB Modem is connected to a portable computer or PC by a USB 

interface. In the service areas or hotspots of HSDPA/UMTS, the Huawei E220 USB 

Modem may access the Internet over the network to transfer and download files or data. 

You can also browse web-site, send and receive messages and emails at any time and 

place. Even when out of the HSDPA/UMTS coverage, you can still enjoy services on 

the Internet with an alternative access through the EDGE/GPRS/GSM network in your 

country. The users can enjoy much more in experiencing the wireless network due to 

the higher speed, the more dependable features and the more convenient operations 

of the HUAWEI E220 USB Modem. Thus, more users will be attracted, and at the same 

time the ARPU of the operators will be increased greatly.
