Title: An Analysis of IMEI Modification Procedures on Quectel Cellular Modules: Technical Mechanisms, Security Implications, and Regulatory Compliance
Abstract
This paper explores the technical processes involved in modifying the International Mobile Equipment Identity (IMEI) on Quectel cellular modules. While Quectel modules are widely deployed in IoT and M2M applications, the ability to alter the IMEI raises significant security and legal concerns. This document analyzes the command interfaces, specifically AT commands and QMI/RIL interfaces, used to access non-volatile memory (NVRAM) for identity modification. Furthermore, it examines the distinction between legitimate repair/recalibration and illicit activities such as device cloning and counterfeiting. The paper concludes with an overview of the regulatory frameworks, including GSMA standards and regional telecommunications laws, that render unauthorized IMEI alteration a criminal offense in many jurisdictions.
The primary command is AT+EGMR. The syntax varies by firmware variant.
For GSM/UMTS/LTE modules (Standard):
AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI"
Example:
AT+EGMR=1,7,"867994056789012"
OK
For Dual-SIM or specific variants (Rare):
Use AT+EGMR=1,10 for SIM 1 and AT+EGMR=1,11 for SIM 2.
An IMEI is a 15-digit unique identifier assigned to every cellular device. It is the hardware’s fingerprint to the mobile network.
For consumer phones, IMEI changes are almost always illegal. For industrial Quectel modules, there are grey areas and legitimate use cases:
