Changing or installing a new IMEI on a Quectel module is a multi-step process involving driver installation, diagnostic mode entry, and using specialized tools like QFirehose, QDM, or AT+EGMR. While it is a valuable capability for integrators and developers, it carries legal responsibilities.
Always ensure you have legal authorization, backup the original IMEI, and test thoroughly on a development setup before deploying to production. With the right preparation and this guide, you can successfully change the IMEI on most Quectel modules in under 15 minutes.

Quectel IMEI change process is widely reviewed by the DIY router community as a powerful but technically demanding task that allows users to bypass carrier-specific device restrictions. While Quectel officially states they do not support IMEI modification, many enthusiasts use specific AT commands to "repair" or spoof IMEIs on modems like the to use phone-only SIM plans on routers. Core Review: Pros and Cons
Modifying the International Mobile Equipment Identity (IMEI) of a Quectel module is typically done for repair purposes, such as restoring a factory IMEI after a firmware corruption. While Quectel does not officially support or provide commands for customers to modify IMEIs, the industry-standard AT+EGMR command is widely used by developers for this purpose. Prerequisites and Installation
To interact with your Quectel module, you must first install the necessary drivers and communication tools on your computer.
Install USB Drivers: Download and install the Quectel USB drivers for your specific operating system (Windows/Linux) to ensure your computer can recognize the module's serial ports.
Identify the AT Port: Once installed, open Device Manager (Windows) to identify the COM port labeled as the Quectel USB AT Port.
Serial Terminal Software: Install a serial port tool like PuTTY or MobaXterm to send commands to the module.
Settings: 115200 baud rate, 8 data bits, 1 stop bit, no parity (115200n81). Guide to Changing IMEI via AT Commands
Follow these steps to read or write a new IMEI number to your Quectel module. quectel change imei install
Query the Current IMEI: Open your serial terminal and enter the following command to see the current 15-digit IMEI: AT+EGMR=0,7 Alternatively, AT+CGSN can be used to read the number.
Write the New IMEI: Use the write variation of the command, replacing the digits below with your target 15-digit IMEI: AT+EGMR=1,7,"123456789012345" Verify and Save: If successful, the module will respond with OK. Restart the module to apply the changes. Confirm the change by running AT+EGMR=0,7 or AT+CGSN again. Critical Considerations

Open QCOM or PuTTY. Connect to the AT COM port (e.g., COM5) at 115200 baud rate. Type:
AT
Expected response:
OK
Now check the current IMEI:
AT+CGSN=1
or
AT+GSN
The module will return its existing IMEI.
While technical documentation or illicit software may suggest methods for "Quectel IMEI installation," the practice is:
Recommendation: If a specific IMEI is required for development or legacy integration purposes, the proper channel is to contact Quectel sales representatives to order modules pre-programmed with custom identifiers during the manufacturing process, or to use the assigned factory IMEI.

Changing the IMEI on a Quectel module involves using specific AT commands through a serial terminal. This process is typically used for "IMEI repair" rather than standard installation. Prerequisites & Installation
Before modifying the IMEI, you must establish a serial connection with the module:
Install Drivers: Download and run the setup file for the Quectel USB Drivers to ensure your PC recognizes the module's COM ports.
Identify the Port: Open Device Manager and find the port labeled Quectel USB AT Port.
Terminal Tool: Use a serial port tool like PuTTY or MobaXterm set to the default baud rate (usually 115200) to send commands. How to Change the IMEI
For most modern Quectel modules (like the EC25 or EG25-G), the following commands are used: Query Current IMEI: AT+CGSN or AT+EGMR=0,7. Write New IMEI: AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI".
Alternative (MikroTik/LTE6): Some kits use AT*MRD_IMEI=W,0101,11JAN1970,YOUR_NEW_IMEI after entering a specific "non-production" mode. Important Constraints & Risks
Legal Restrictions: Tampering with an IMEI is illegal in many jurisdictions, including the UK and India, as it can be used to bypass blacklists or interfere with law enforcement.
Firmware Support: Quectel officially states they do not provide commands to modify IMEIs to customers. Some firmware versions may block these commands entirely.
Carrier Issues: If a carrier detects an unauthorized IMEI change, they may block the device from the network. How to change the IMEI of Mikrotik SXT LTE6 kit
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. Need more help
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:
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.
Here’s a clear, technically appropriate text regarding IMEI modification on Quectel modules, intended for educational or developmental use (e.g., testing in a lab environment).
Important Legal Notice:
Changing the IMEI of a Quectel cellular module may violate local laws and regulations. IMEI modification is typically permitted only for authorized testing, development, or with explicit device owner consent. Do not use this for fraudulent or illegal purposes.
