One of the most frequent technical queries regarding these modules involves the modification of the International Mobile Equipment Identity (IMEI). This comprehensive guide explains the technical mechanisms behind IMEI management on Quectel modules, the specific AT commands involved, and the essential troubleshooting steps. Understanding IMEI in Quectel Hardware
Quectel modules store the IMEI in a non‑volatile memory partition. Depending on the module family and firmware version, the IMEI can be modified using one of several methods:
On many Quectel modules (EC25, EG95, etc.), the command syntax is: quectel change imei
AT+QENG=1
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.
