In the world of IoT (Internet of Things), Quectel is a giant. Their modules—ranging from the legacy GSM/GPRS M95 to the cutting-edge 5G RM520N—power millions of devices worldwide, from electric vehicle chargers and industrial routers to asset trackers and smart meters.

Mobile networks maintain Equipment Identity Registers (EIR). If a Quectel module uses a cloned or invalid IMEI, it may be banned permanently (IMEI blacklist).
Factory Backup Utility: Automatically backs up the original factory IMEI to a secure, read-only partition before any modification. This allows for a "Restore to Factory" option if network registration fails. quectel change imei

Furthermore, many cellular providers use IMEI/TAC (Type Allocation Code) validation. If a module’s IMEI is changed to a string that does not match the device’s hardware profile, the network may reject the connection, or the device may fail to receive necessary over-the-air (OTA) updates. Conclusion
The unauthorized alteration of IMEI numbers undermines the integrity of mobile networks, facilitates the use of stolen hardware, and violates criminal statutes in most jurisdictions. Therefore, research into these mechanisms should be strictly limited to defensive security analysis and the development of anti-tampering technologies. the network may reject the connection
Quectel modules with modified IMEIs cannot receive official firmware updates. Over-the-air (OTA) provisioning may fail, bricking the device.
