This section provides a safe, reproducible method. Warning: Incorrect AT commands can permanently damage your modem. Proceed at your own risk.
Many Huawei routers and modems have this feature hidden within the settings.
If the risk seems too high, consider these alternatives:
However, for true low-level control, nothing replaces a direct Huawei Modem Terminal Download.
Depending on your specific Huawei model, there are three main ways to access the terminal.
Summary statement
A. Identifying device and chipset
B. Accessing terminal (AT/serial) interface
C. Official firmware update (recommended)
D. Recovery/low-level flashing
E. NVRAM / IMEI / configuration backup and restore

Huawei Modem Terminal: Guide to Features and AT Commands Huawei Modem Terminal
is a specialized utility used to interact with Huawei 3G and 4G USB modems by sending AT commands over a serial interface
. It is primarily utilized by advanced users and technicians to modify device behavior, such as disabling "HiLink" mode or unlocking specific network bands. vutlan.atlassian.net Core Functionality
The terminal allows you to communicate directly with the modem's firmware through a COM port. Common use cases include: vutlan.atlassian.net Mode Switching
: Changing a modem from "HiLink" (web interface mode) to "Stick" mode (serial interface mode). Port Management : Activating debug ports or network card interfaces (NCM). Information Retrieval
: Checking signal strength (RSSI), IMEI, firmware versions, and supported command lists. Network Locking
: Forcing the modem to stay on specific frequency bands or network types (e.g., 3G only or LTE only). vutlan.atlassian.net Common AT Commands
Once connected, you can input these commands into the terminal:
Basic "handshake" to check if the modem is responsive; should return "OK". Displays manufacturer information and model details. Checks the current radio signal strength. AT^SETPORT? Queries current port configurations. AT^U2DIAG=0 Switches the modem to "Modem Only" mode. Restarts the modem without physically unplugging it. How to Use the Terminal Preparation : Connect your Huawei modem to a USB port. Ensure the latest modem drivers
are installed so the computer recognizes the serial interface. Connection : Launch the program and select the port labeled "HUAWEI Mobile Connect - PC UI Interface" from the dropdown menu. Huawei Modem Terminal Download
. Type your desired command in the bottom input field and press Enter. A successful command usually returns a "Receive: OK" message. vutlan.atlassian.net
Depending on your technical need, you will require one of these three common tools:
PuTTY (Recommended): A lightweight, free terminal emulator used to send AT commands to USB modems or access CLI on routers.
Huawei eNSP (Enterprise Network Simulation Platform): A specialized simulator for learning and testing Huawei device CLI commands.

Step-by-Step: Connecting via Terminal (PuTTY)
If you are trying to communicate with a Huawei USB modem or router via serial terminal: Find the COM Port: Connect your Huawei device to your PC. Open Device Manager on Windows.
Expand Modems and Ports (COM & LPT). Look for "Huawei Mobile Connect - PC UI Interface" and note the COM number (e.g., COM3). Configure PuTTY: Launch PuTTY. Select the Serial radio button.
Enter the Serial line (e.g., COM3) and Speed (typically 9600 or 115200). Open Connection: Click Open. A black terminal window will appear.
Type AT and press Enter. If you receive an OK response, your terminal connection is successful. 4. Alternative: Accessing the Web Terminal (ONT/Router)
For Huawei GPON or Fiber modems, the "terminal" is usually a web-based GUI: Address: Typically 192.168.100.1 or 192.168.1.1.
Credentials: Check the label on the bottom of your device. Common defaults include: Username: admin or telecomadmin. Password: admin or admintelecom. Important Safety Note This section provides a safe, reproducible method
Only download firmware and management software from official Huawei Support or Consumer sites. Third-party "unlocker" tools may contain malware. If you'd like, let me know:
The exact model number of your Huawei modem (e.g., B612, E3372).
If you are trying to unlock the device or just configure Wi-Fi.
The operating system you are using (Windows, macOS, or Linux).
I can then provide specific AT commands or the exact firmware link for your device.
Logging In to a Device for the First Time Through a Console Port
Once your terminal is active, here are the most valuable commands. (Note: Commands may vary by chipset—HiSilicon vs. Qualcomm.)
| Function | AT Command | Expected Output |
| :--- | :--- | :--- |
| Signal Quality | AT^HCSQ | ^HCSQ: "LTE",20,49,149,20 |
| Network Info | AT^NETINFO | Current cell ID, MNC, MCC |
| Device IMEI | AT^IMEI | 15-digit IMEI |
| Unlock modem | AT^CARDLOCK="code" | OK if valid |
| Band Locking | AT^SYSCFGEX="03",3FFFFFFF,1,2,4C0,,"LTE" | Sets LTE band priority |
| Factory reset | AT^RESET | Modem reboots |
| Hardware Revision | AT^HWVER | Board ID and chipset |
Important: To lock bands, you need a hex mask calculator. For example, 3FFFFFFF means all bands. Changing this to 200000002000 (Band 3 only) requires careful calculation.
Before any terminal software can work, your PC must recognize the modem’s diagnostic port (often COM3, COM4, etc.).
