Change Imei Install [repack]: Quectel
Note: Ensure the new IMEI is exactly 15 digits long and wrapped in quotation marks.
This is the most widely discussed method and relies on a specific AT command that was historically supported on many Quectel modules but is increasingly being removed or disabled. The command is AT+EGMR .

Navigate to Start Clients -> Software Download -> Backup . Save a backup copy of your module's original .qcn file. Never skip this step.
An evaluation board or a device integrated with a Quectel module (e.g., EC25, EP06, RM500Q, BG96). quectel change imei install
Ensure your USB adapter board is supplied with adequate external power (5V, 2A minimum). Relying solely on a PC USB port often triggers brownouts.
Install the official Quectel LTE/5G Windows or Linux USB drivers to expose the virtual COM ports.

Re-open your serial terminal and reconnect to the Quectel USB AT Port . Query the identity profile again: AT+GSN Use code with caution. Note: Ensure the new IMEI is exactly 15
The ability to freely change IMEIs on Quectel modules is a dwindling practice. As legal pressures increase and anti-fraud measures tighten, manufacturers like Quectel are actively closing these loopholes in their firmware. The future points toward where identity is managed securely by the carrier, and toward certified hardware where the IMEI is a hardware-trusted value. The methods described in this article are based on historical and current community knowledge, but they are not guaranteed to work on newer modules or future firmware releases.
The current firmware on the module has disabled direct IMEI modification via the AT+EGMR command for security compliance.
This report addresses the technical inquiry regarding the modification (changing) of the International Mobile Equipment Identity (IMEI) on Quectel cellular modules. While the technical capability to alter IMEI numbers on such devices exists via AT commands or proprietary tools, this practice is heavily restricted by hardware design (Write-Once fuses) and is illegal in most jurisdictions.
Applications like QCOM (Quectel's official tool), PuTTY, or Tera Term are required to send commands to the module. Step-by-Step Installation and Modification Process I can provide the specific firmware commands or
Wait for the terminal response. A successful command returns: OK Use code with caution. Method B: Engineering Mode Unlock (Advanced Modules)
Open Command Prompt as Administrator and navigate to the QFirehose folder.
Once the ports are mapped, use a terminal program to establish communication with the module. Open your terminal emulator (e.g., QCOM or PuTTY).
Enter the required security access code or engineering mode command (varies strictly by chipset model). Use the proprietary write command structure: AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI" Use code with caution.
