Technical Deep Dive: Modifying IMEI on Quectel Modules Managing the International Mobile Equipment Identity (IMEI) of a Quectel module—such as the popular
—is a common task for developers and hobbyists. Whether you are performing a "repair" after a corrupted firmware update or need to align a 5G CPE device with a specific IoT plan, the process involves precise AT commands and driver installation. ⚠️ Legal and Practical Warning Before proceeding, understand that changing an IMEI number is illegal in many jurisdictions
, including the United States and India, as it can be used to bypass blacklists or commit fraud. Quectel officially does not support or recommend user-level IMEI modification. Proceed only if you have a legitimate, legal reason, such as restoring a device's original identity after a repair. Phase 1: Driver and Tool Installation
To communicate with a Quectel module via a PC, you must first install the correct serial port drivers.

To change the IMEI on a Quectel modem, you typically use specific AT commands through a terminal interface. While Quectel does not officially document or support this feature for general users, it is often possible using the AT+EGMR command, which is frequently used for "repairing" or setting the identifier on modules like the EG25-G. Prerequisites & Installation
Before running commands, you need a way to communicate with the modem:
Drivers: Ensure you have the proper USB drivers installed for your OS to recognize the modem's diagnostic or serial ports.
Terminal Software: Use a serial terminal like Minicom, PuTTY, or QNavigator.
Modem Access: On Linux systems (like the PinePhone), you must often stop the modem-manager service first to prevent it from locking the serial port. Step-by-Step Procedure
Check Current IMEI:Open your terminal and verify the existing IMEI using:AT+GSN or AT+EGMR=0,7.
Apply New IMEI:Use the following command format to update the identifier:AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI".
Verify the Change:Run AT+GSN again to confirm the modem reflects the new number.
Reboot the Modem:To ensure the change is persistent and active on the network, restart the device:AT+CFUN=1,1. Important Considerations
Legal Compliance: In many regions, changing an IMEI is illegal and can lead to network blacklisting or prosecution.
Official Support: Quectel representatives generally state that they do not provide commands for modification and cannot guarantee device stability afterward.
Integration: For advanced users, tools like the asterisk-chan-quectel driver on GitHub allow for complex call handling using specific IMEIs.
Device Specifics: On some Android-based devices, you may need root access and a terminal emulator to run AT+EGMR=1,10,"IMEI_NUMBER" instead. Disclaimer: Changing the IMEI on a cellular module
Use IMEI overwrite via USB QMI or MBIM commands if supported, or test using a simulated environment (e.g., Quectel QCM) rather than real cellular networks.
You're looking to modify the IMEI (International Mobile Equipment Identity) on a Quectel module, which is a type of cellular module used in IoT devices.
Disclaimer: Changing the IMEI on a cellular module or any device may be subject to local regulations and laws. It's essential to ensure that any modifications comply with the relevant laws and regulations in your region.
That being said, here are the general steps to change the IMEI on a Quectel module:
Prerequisites:
Step-by-Step Instructions:
AT and press Enter to enter AT command mode. The module should respond with OK.AT+QCFG="imei",1 and press Enter. This command enables IMEI modification.AT+QIMEI="XXXXXXXXXXXXXXX" and press Enter, replacing XXXXXXXXXXXXXXX with the new IMEI value (15 digits).AT+CGMI and press Enter to verify that the new IMEI has been set.Generate a feature: To generate a feature for changing the IMEI, you can create a simple script using a programming language like Python.
Here's a basic example using Python and the pyserial library:
import serial
def change_imei(imei):
# Open the serial port
ser = serial.Serial('COM3', 115200, timeout=1) # Replace COM3 with your actual serial port
# Enter AT command mode
ser.write(b'AT\r')
response = ser.readline().decode().strip()
if response != 'OK':
print('Error: Failed to enter AT command mode')
return
# Enable IMEI modification
ser.write(b'AT+QCFG="imei",1\r')
response = ser.readline().decode().strip()
if response != 'OK':
print('Error: Failed to enable IMEI modification')
return
# Set the new IMEI
ser.write(f'AT+QIMEI="imei"\r'.encode())
response = ser.readline().decode().strip()
if response != 'OK':
print(f'Error: Failed to set IMEI to imei')
return
print(f'IMEI changed to imei')
# Example usage
new_imei = '123456789012345'
change_imei(new_imei)
This script is for illustrative purposes only and may require modifications to work with your specific Quectel module and setup.
Keep in mind: Changing the IMEI on a cellular module may have implications for device certification, regulatory compliance, and network operator requirements. Ensure that you understand the potential consequences before making any modifications.
The International Mobile Equipment Identity (IMEI) is a unique 15-digit code used to identify cellular devices on a network. For Quectel modules, changing the IMEI is often necessary for legitimate hardware repairs or identity restoration after data corruption.
Below is a detailed guide on the installation and technical process for modifying the IMEI on a Quectel module using AT commands. 1. Prerequisites and Installation
To interact with a Quectel module, you must first install the necessary drivers and software on your host machine.
USB Driver Installation: Download and install the official Quectel LTE Windows USB Driver. Once installed, connect the module to your computer via USB. Open the Device Manager to verify that several serial ports have appeared, specifically the Quectel USB AT Port. Quectel module (e
Serial Port Tool: Use a serial communication tool such as PuTTY, MobaXterm, or QCOM (Quectel's proprietary tool) to send commands to the module.
Port Settings: Configure your serial tool to the following default settings: Baud Rate: 115200 Data Bits: 8 Parity: None Stop Bits: 1 2. Verifying Current IMEI
Before attempting a change, verify the module's current identification to ensure it is communicating correctly. Open the serial port corresponding to the AT Port. Send the following command to query the current IMEI: AT+CGSN Use code with caution.
Alternatively, use AT+EGMR=0,7 to retrieve the IMEI string specifically.
Record the current number as a backup in case you need to restore the original factory settings. 3. How to Change the IMEI (Step-by-Step)
Quectel modules utilize specific AT commands for identity management. The most common command for this task is AT+EGMR.
Stop Conflicting Services: If you are using Linux (e.g., PinePhone), stop the ModemManager service first to prevent it from locking the serial port: systemctl stop ModemManager.service ``` Use code with caution.
Execute the Change Command: In your serial terminal, enter the command below, replacing the placeholder with your desired 15-digit number: AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI" ``` Use code with caution.
Confirm the Result: If successful, the module will return an OK response.
Verify the New IMEI: Run AT+CGSN again to confirm the module is now broadcasting the new identification.
Reboot: Restart the module to ensure the changes are finalized across all internal systems. 4. Troubleshooting and Firmware Issues
If the command fails or returns a CME ERROR, consider the following: How to get Quectel standard firmware - Technical Subjects
AT+EGMR commands.Quectel_QCM_NDIS_Driver or Quectel_USB_Driver to expose diagnostic ports (e.g., COM port for AT commands).qmi_wwan or option driver – no extra install usually needed.Note: The following procedure is known to work on Quectel EC25, EC21, EG95, BG96, and UC20 with firmware version R02 or later. For older modules (UC15, M95), a different method (using QLoader) is required.
This is not a standard "install" feature for end-users. Quectel does not provide a one-click installer to change IMEI. Instead, it is a low-level diagnostic command feature.
To enable IMEI change functionality on a Quectel module, you need to install the proper USB drivers and use terminal software.
