ZTE UI AT Interface (COM16) Driver

The ZTE UI AT Interface (COM16) driver allows Windows to recognize the AT-command interface exposed by compatible ZTE USB devices. It is intended for users whose ZTE modem or mobile broadband hardware appears as an unknown device, shows a warning in Device Manager, or cannot communicate with its connection software.

This interface provides a serial communication channel for supported management and diagnostic commands; it is not necessarily the driver responsible for the device’s entire internet connection. COM16 is the port number assigned by Windows and may differ on another computer.

Key Features

• USB interface recognition: Helps Windows identify the ZTE AT interface rather than leaving it listed as an unrecognized USB component.
• Serial communication support: Enables compatible software to send AT commands for functions such as checking device status, where supported by the hardware.
• Device Manager integration: Makes the interface available as a COM port so applications can select the appropriate connection.
• Legacy Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your specific device and Windows architecture.

How to Install ZTE UI AT Interface (COM16) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the interface’s hardware IDs if you need to distinguish between similar ZTE driver packages.
2. Choose a compatible package. Before starting your ZTE UI AT Interface (COM16) driver download for Windows, verify the supported hardware and operating systems. If offered as a free download, still check the source and publisher.
3. Prepare the files. Extract the downloaded archive if necessary. Follow any included instructions about connecting or disconnecting the USB device during setup.
4. Install the driver. Run the provided installer, or open Device Manager, right-click the affected interface, choose Update driver, and browse to the extracted driver folder.
5. Verify recognition. Restart if prompted, reconnect the device, and confirm that the interface appears without a warning icon. Select its assigned COM port in your compatible application.

Keep the driver updated when a compatible release addresses connection problems or improves reliability. Choose the latest version verified for your hardware, not simply the newest package available. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed. Avoid an unnecessary update if your current setup works reliably.
