HUAWEI Mobile Connect - 3G PC UI Interface (COM22) Driver

The HUAWEI Mobile Connect – 3G PC UI Interface (COM22) driver enables Windows to recognize the PC UI serial interface exposed by a compatible Huawei mobile broadband device. It is intended for users whose Huawei modem or connection software cannot communicate with this interface, or whose Device Manager shows a missing driver or warning icon.

Although associated with mobile networking hardware, this component provides a communication port for compatible software rather than acting as the complete mobile broadband connection driver.

Key Features

• PC UI interface support: Allows compatible Huawei utilities to communicate with the device through its serial interface.
• Windows device recognition: Helps Windows identify the interface correctly instead of listing it as an unknown device.
• Legacy Windows compatibility: Supports Windows 10, 8.1, 7, Vista, and XP when you select a package appropriate for your hardware and system architecture.
• COM-port identification: Makes the interface available to software that uses serial ports. COM22 is the assigned port number on this system; another computer may assign a different number.

How to Install HUAWEI Mobile Connect – 3G PC UI Interface (COM22) Driver

1. Check your system and hardware. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the interface’s Hardware IDs to help identify a matching driver package.
2. Choose a compatible download. Before starting a HUAWEI Mobile Connect – 3G PC UI Interface (COM22) driver download for Windows, verify the package’s supported devices and operating systems. For Windows 10/11 searches, note that Windows 11 compatibility is not confirmed here.
3. Download and prepare the files. Obtain the driver from a trusted source. A free download should not require an unrelated paid driver updater. Extract the archive if necessary.
4. Install the driver. Run the included installer, if provided, or open Device Manager, right-click the affected interface, choose Update driver, and browse to the extracted driver folder. Follow the prompts.
5. Verify recognition. Restart if requested, reconnect the Huawei device, and check that the interface appears without a warning icon. If your software requires a specific COM port, confirm its current assignment.

Keep the driver updated when a compatible release addresses a problem or improves reliability. Choose the latest version validated for your specific Huawei hardware and Windows edition rather than assuming every newer package will work. Before an update, retain a working driver copy so you can roll back if needed.
