IMEI is a 15-digit number that serves as a unique identifier for a mobile device. It is used to identify a device on a cellular network and is essential for various purposes such as:

AT+CFUN=1,1

Once the ports are mapped, use a terminal program to establish communication with the module. Open your terminal emulator (e.g., QCOM or PuTTY).

This guide provides an exhaustive, step-by-step technical breakdown of how to change, configure, and verify the IMEI on Quectel modules using standard AT commands. ⚠ Important Legal and Compliance Notice quectel change imei install

OK

Select the corresponding to the Quectel USB AT Port . Set the speed to 115200 baud (default). Type AT and press Enter. The module should respond with OK . 2. Query Current IMEI

Newer 5G modules often require target slot indexing if they support dual SIM or dual connectivity features: AT+EGMR=1,7,"123456789012345",0 Use code with caution. (The trailing ,0 specifies the first SIM slot index). Method C: Engineering Mode Command (Alternative Chipsets)

After completing the installation and modification workflow, you must verify that the cellular stack registers the change successfully. Verification Steps Before attempting any modification, ensure you have the

Upon installation, check the . You should see multiple ports listed under "Ports (COM & LPT)," including the Quectel USB AT Port . 3. Install a Serial Port Tool

This guide provides a comprehensive, technical overview of how to change and verify the IMEI on Quectel modules using AT commands and official software tools. Legal and Regulatory Warning

Verify the existing IMEI and connection status by running: AT+GSN Use code with caution. AT+CGSN Use code with caution. The module will return the current 15-digit IMEI string.

Only alter an IMEI if you own the device, operate in a closed lab environment, or have explicit authorization for testing, compliance, or repair purposes. Open your terminal emulator (e

Applications like QCOM (Quectel’s official tool), PuTTY , or Tera Term .

If the module returns ERROR , ensure your AT command syntax is correct and you are using the correct AT Port, not the DM or NMEA port.

By following this structured approach, engineering teams can successfully simulate different hardware endpoints, ensuring thoroughly tested IoT assets before wide-scale market deployment.
