Introduction

The Quectel EC25 series is a family of LTE Cat 4 wireless communication modules widely used in Internet of Things (IoT) devices, automotive telematics, industrial routers, and portable hotspots. Each module is factory-assigned a unique International Mobile Equipment Identity (IMEI) number—a 15-digit code that serves as the device’s unique identifier on cellular networks. Under normal circumstances, the IMEI is permanent and non-changeable. However, advanced users, developers, and sometimes unauthorized individuals may seek to alter this identifier. This essay provides a detailed technical examination of why, how, and under what conditions the IMEI on a Quectel EC25 module can be changed, the commands involved, and the associated risks. quectel ec25 change imei

Conclusion

The Quectel EC25’s IMEI can be changed using the proprietary AT+EGMR command, provided the module’s firmware permits write access and the user has legal authority to do so. While technically straightforward, the procedure is heavily restricted by law and network policy. For legitimate engineering (e.g., recovering a corrupted IMEI), users should contact Quectel support for authorized tools. For any other purpose, altering the IMEI is strongly discouraged and often illegal. Understanding the mechanism does not imply endorsement—rather, it highlights the importance of secure IMEI storage and the risks of circumventing device identity protections.
