Overview
The Huawei E220 is a portable USB 3G modem (also known as a “wireless broadband stick”) produced by Huawei Technologies Co., Ltd., a Chinese multinational telecommunications equipment manufacturer. Designed for consumer and small‑business markets, the device enables mobile broadband connectivity by interfacing with third‑generation (3G) cellular networks and presenting a standard USB interface to personal computers.
Technical specifications
- Network compatibility: Supports UMTS/HSPA (3G) bands 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz; backward compatible with GSM/GPRS/EDGE (2G) on 850/900/1800/1900 MHz.
- Interface: USB 2.0 Type‑A connector; recognized by Windows operating systems as a virtual CD‑ROM containing drivers and as a network adapter after driver installation.
- Data rates: Maximum theoretical download speed of up to 7.2 Mbps (HSDPA) and upload speed of up to 384 kbps (HSUPA).
- Power: Draws power directly from the host computer’s USB port; does not require an external power source.

Release and market reception
The Huawei E220 was introduced in the mid‑2000s (circa 2007) as part of Huawei’s expanding line of mobile broadband devices. It gained popularity in regions where 3G coverage was emerging, offering a low‑cost alternative to built‑in cellular modems in laptops. The device was widely distributed by mobile network operators and third‑party retailers, often sold bundled with data plans or as a “pay‑as‑you‑go” dongle.
Compatibility and driver support
Official driver packages were provided for Microsoft Windows (XP, Vista, 7) and later updated for newer Windows versions. Unofficial driver support and community‑maintained tools have enabled operation under Linux (via the usb_modeswitch utility) and macOS, though official support from Huawei was limited to Windows platforms.
Legacy
The Huawei E220 contributed to the early adoption of mobile broadband in consumer markets, preceding later USB‑type 4G/LTE devices. Its form factor and plug‑and‑play approach influenced subsequent generations of portable cellular modems. The model has largely been superseded by newer devices supporting higher‑speed LTE and 5G networks.
