Sierra Wireless Data Port (UMTS) (COM6) Driver

The Sierra Wireless Data Port (UMTS) (COM6) driver helps Windows recognize and communicate with the serial data interface exposed by a compatible Sierra Wireless UMTS modem. It is intended for users setting up mobile broadband hardware or troubleshooting a missing or unrecognized data port in Device Manager.

Key Features

• Data port recognition: Enables Windows to identify the modem’s data interface so compatible software can access it.
• Serial communication support: Provides the driver interface used for communication through the assigned COM port. COM6 is the current port designation; Windows may assign a different number after installation.
• Legacy Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Individual packages may support only some of these versions, so check the package details.
• Troubleshooting support: Installing the correct driver may resolve recognition issues caused by a missing, damaged, or incompatible installation. Mobile broadband connectivity may also require other modem drivers or connection software.

How to Install Sierra Wireless Data Port (UMTS) (COM6) Driver

1. Identify your hardware and Windows version. Open Device Manager and check the device’s Properties. Note its hardware IDs and whether your Windows installation is 32-bit or 64-bit; the COM6 label alone does not identify the correct driver package.
2. Choose a compatible package. Before starting your Sierra Wireless Data Port (UMTS) (COM6) driver download for Windows, confirm that the package matches your modem model, hardware IDs, and operating system. For Windows 10/11 systems, do not assume shared compatibility: Windows 11 is not included in the listed supported operating systems.
3. Download and extract the files. If a free download is offered, verify its source and check the publisher information where available. Extract compressed files before proceeding.
4. Install the driver. Run the supplied installer, if included, and follow its instructions. Alternatively, right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder.
5. Verify the result. Restart Windows if prompted, then check Device Manager for warning icons. Confirm the assigned COM port and select it in your modem software if necessary.

Keep the driver updated when a compatible release addresses a problem or adds needed support. Choose the latest version approved for your specific hardware and Windows release, rather than installing an unrelated package simply because it is newer. Before an update, retain the working installer or create a restore point so you have a recovery option.
