You cannot determine safety based on the filename alone. Cybercriminals often disguise malware with names that mimic legitimate software. The genuine version of Huawei’s modem software is usually safe, but malicious copies exist.
If the standard software works fine, why risk the terminal? Because the standard software can’t do these five things:
If you're accessing a terminal directly: huawei modem terminal.exe
Authentication: You might need to log in with a username and password to access certain commands or configurations.
Below is a concise, step-by-step guide to connect to and manage a Huawei USB modem (dongle) from Windows using a terminal-like tool (terminal.exe or similar CLI). Assumptions made: modem uses standard Huawei HiLink or serial/PPP interface; you have Windows 10/11; terminal.exe refers to a simple serial/command terminal program (if you meant a different tool, the steps still apply conceptually). You cannot determine safety based on the filename alone
In many jurisdictions, changing a modem’s IMEI is a criminal offense (e.g., UK Computer Misuse Act, US FCC regulations). However, network engineers use it for legitimate testing. The terminal can send factory-level commands like AT^IMEI="NEW_IMEI"—but do not do this unless you own the device and understand local laws.
| Command | Function | Expected Response |
| :--- | :--- | :--- |
| AT | Basic handshake | OK |
| ATI | Modem model/firmware info | Manufacturer: Huawei |
| AT^CARDLOCK? | SIM lock status | ^CARDLOCK: 0,0 = Unlocked |
| AT+CSQ | Signal strength | +CSQ: 20,99 (20 is good) |
| AT+COPS? | Current network operator | +COPS: 0,2,"310410",7 (T-Mobile) |
| AT^U2DIAG | Change USB modes | ^U2DIAG: 0 = Modem only |
| AT^RESET | Soft reset | Resets modem immediately | Authentication : You might need to log in
In general, executable files with similar names are often associated with Huawei’s mobile broadband devices (3G/4G/LTE USB modems). These modems typically come with software that allows users to manage connections, send SMS, check data usage, and configure network settings. The .exe extension indicates it is a Windows application.
