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

Changing the International Mobile Equipment Identity (IMEI) of a cellular module is a complex procedure often necessitated by regional regulations, network compatibility issues, or device testing requirements. When working with Quectel modules—such as the popular EC25, EP06, or RM500Q series—understanding how to "install" or reconfigure an IMEI requires a mix of specific hardware drivers, AT commands, and specialized software tools.

This guide provides a comprehensive overview of the process, the tools required, and the critical legal considerations involved. 1. Critical Legal and Ethical Warning

Before proceeding, it is vital to understand that changing an IMEI is illegal in many jurisdictions, including the United States (under the Mobile Device Theft Deterrence Act), the UK, and much of the EU. The IMEI is intended to be a unique, permanent identifier.

Authorized Use: This process should only be performed for legitimate development purposes, such as restoring an IMEI to a repaired board or testing private LTE/5G network authentication.

Unauthorized Use: Changing an IMEI to bypass blacklists or "unblock" stolen devices is a criminal offense in many regions. 2. Prerequisites for Installation

To interact with a Quectel module and modify its internal identity, you need a specific environment: quectel change imei install

Quectel USB Drivers: You must install the official Quectel Windows/Linux USB drivers to expose the AT Port and the Diagnostic (DM) Port.

Hardware Interface: The module must be connected via a Mini PCIe to USB adapter, an M.2 to USB bridge, or a development evaluation board (EVB).

Terminal Software: Tools like QCOM (Quectel’s proprietary utility), Putty, or Tera Term are required to send commands.

Quectel QPST/QFlash: In some recovery scenarios, these tools are used to interact with the Qualcomm-based firmware layers. 3. The "Installation" Process: Step-by-Step Step A: Identify the Current State

Connect your module and open your terminal software. Select the Quectel AT Port (usually at 115200 baud). Check the current IMEI by typing: AT+GSN Use code with caution.

This confirms the module is communicating and displays the current 15-digit identifier. Step B: Entering Production/Engineering Mode

Quectel modules often require a "security password" or a specific command to unlock the write-protection on the IMEI field. Depending on the specific firmware version, you may need to use: AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI" Use code with caution.

Note: The 1,7 parameters specifically target the IMEI storage in the module's NVRAM. Step C: Verifying the Change

After sending the command, the module should return OK. To finalize the "installation" of the new identity, you must restart the module: AT+CFUN=1,1 Use code with caution.

Once the module reboots, run AT+GSN again to verify the new IMEI is active. 4. Troubleshooting Common Issues If the command returns ERROR, consider the following:

Locked Firmware: Some newer firmware versions (especially those sold to specific carriers) have the IMEI field "hard-fused." In these cases, standard AT commands will not work.

QCN Backup: Professional engineers often use the Quectel NV Item Manager to back up the QCN file. If an IMEI "install" fails, the QCN can be edited and reflown back into the module using QPST.

Driver Conflicts: Ensure that no other software (like Windows Modem Manager) is occupying the AT port while you are trying to send commands. 5.
