ZTE Mobile Connect AT Device (COM25) Driver

The ZTE Mobile Connect AT Device (COM25) driver lets Windows communicate with the AT-command interface of a compatible ZTE USB modem or mobile broadband device. You may need it if Device Manager shows an unrecognized device, the COM25 interface is missing, or modem-management software cannot communicate with your hardware.

Key Features

• AT-command communication: Provides a serial interface that compatible applications can use to query device information, check modem status, and perform supported control functions.
• USB device recognition: Helps Windows identify the ZTE AT interface correctly rather than leaving it listed as an unknown device.
• COM-port access: Makes the interface available to software through a Windows COM port. Although this device is labeled COM25, the assigned port number can differ between computers or USB connections.
• Legacy Windows support: Intended for compatible configurations running Windows 10, 8.1, 7, Vista, or XP. Select a package that matches your Windows version and 32-bit or 64-bit architecture.

How to Install ZTE Mobile Connect AT Device (COM25) Driver

1. Check your device and system. Open Device Manager and locate the ZTE interface, which may appear under Ports (COM & LPT) or Other devices. Check its hardware IDs and confirm your Windows version and architecture before choosing a driver.
2. Select a compatible package. When choosing a ZTE Mobile Connect AT Device (COM25) driver download for Windows, verify that it supports your specific hardware. Look for the latest version compatible with your system, not simply the newest available package. A free download should still come from a trustworthy source.
3. Extract and install. If the package includes an installer, run it and follow its instructions. Otherwise, extract the files, right-click the device in Device Manager, select Update driver, and browse to the extracted folder.
4. Reconnect if prompted. Follow any restart or reconnection instructions. Allow Windows to finish detecting the interface before opening your modem software.
5. Verify operation. Confirm that Device Manager shows no warning icon and note the assigned COM port. Configure your application to use that port if required.

Keep the driver updated when a compatible release addresses connection issues or improves device recognition. For Windows 10/11 systems, check support carefully: Windows 10 is listed for this device, but Windows 11 compatibility is not confirmed here. Before an update, retain a working driver package so you can restore it if necessary.
