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.

Changing the IMEI (International Mobile Equipment Identity) of a Quectel module is a procedure typically used for "repair" purposes, such as restoring a corrupted IMEI (e.g., IMEI showing as "0000..." or "null"). While it is technically possible via AT commands on many models, it is important to note that Quectel does not officially support or document this command, and changing an IMEI may be illegal in many jurisdictions. Prerequisites & Preparation

Before attempting any changes, you must establish a stable communication link with the modem.

Drivers: Ensure you have installed the correct Quectel USB Drivers for your operating system (Windows or Linux) to recognize the modem's diagnostic and AT ports.

Terminal Software: Use a serial terminal like QCOM (Quectel's tool), PuTTY, or minicom (Linux) to send commands.

Identify the Port: The AT commands must be sent to the specific "AT Port" or "Modem Port" (e.g., /dev/ttyUSB2 on Linux or a specific COM port in Windows Device Manager).

Stop Interfering Services: On Linux systems, you must stop the ModemManager service (e.g., sudo systemctl stop ModemManager) as it may lock the serial port. Execution via AT Commands

The most common method for modifying the IMEI on Quectel modules (such as the EG25-G, EC25, and EP06 series) is the AT+EGMR command. Using Quectel voice over UAC #2 - GitHub
