You're looking for information on how to change the IMEI (International Mobile Equipment Identity) of a Quectel EC25 module. The Quectel EC25 is a popular LTE module used in various IoT and M2M applications. Changing the IMEI of such a module can be necessary for certain applications, especially when multiple devices need to share a single cellular subscription or for testing purposes. However, it's crucial to note that modifying the IMEI can be against the law in some jurisdictions and can also violate the terms of service with your mobile network provider. Always ensure you have the legal right and proper authorization to make such changes.
Changing the IMEI of a Quectel EC25 module involves specific AT commands. However, consider the legal implications and whether such a change aligns with your use case and compliance requirements. Always consult with a legal expert or relevant authorities if you're unsure about the regulations in your area.

Before resorting to IMEI modification, consider these alternatives:
If the IMEI resets back to original factory parameters upon power-cycling, the module firmware might possess an OTP (One-Time Programmable) secure lock or secure boot enabled by the hardware integrator.

The fastboot oem stay command tells the bootloader to remain in fastboot mode after the reboot so you can continue with the recovery procedure.
The module should reply:
If the above command fails, try the alternative syntax structure: AT+EGMR=1,5,"123456789012345" Use code with caution. Or simply: AT+CGSN="123456789012345" Use code with caution. Method 3: Using the Quectel +QNV Command (Advanced)
In rare, legitimate diagnostics, an IMEI might become corrupted and need rewriting.
To restore the factory IMEI, simply re-run AT+EGMR with the original number you saved in Step 2. However, it's crucial to note that modifying the
One of these will work depending on your EC25 firmware revision (check with AT+CGMR ).
Modifying the International Mobile Equipment Identity (IMEI) of a Quectel EC25 module is a sensitive procedure typically reserved for legitimate device repair or manufacturing restoration. While the process is not documented in standard AT command manuals, it can be achieved using specific engineering commands.
