To change the IMEI on a Quectel EC25 modem, you can use the AT+EGMR command. While Quectel does not officially document this for customer use to avoid legal or carrier issues, it is often used for "IMEI repair" when the number has been lost during firmware updates.  Steps to Change IMEI 

• Testing & Certification: During type approval or carrier certification, labs may need to temporarily use a test IMEI range or mimic an existing certified device.
• Development Kits: Prototype boards often ship with a generic or invalid IMEI. Changing it to a valid, allocated range is required for live network testing.
• IMEI Cloning for Redundancy (Controversial): Some industrial setups clone IMEIs from a primary module to backup modules for seamless failover. This is legally gray and often forbidden by carriers.

Interface Lock: Modification may fail if the module is connected via certain WAN interfaces. Disconnect external ethernet or network cables during the process. 2. Fastboot Method (For Advanced Recovery) quectel ec25 change imei
