If a modified IMEI is detected as invalid or suspicious, carriers can blacklist the device entirely, preventing network registration across multiple providers.
For modules based on Qualcomm chipsets, the QMI protocol allows direct communication with the baseband. Tools such as QPST (Qualcomm Product Support Tools) can be used to access the NVRAM items.
The file contains device-specific calibration data and identifiers, including the IMEI. Using Qualcomm tools like QPST/QFIL, it is theoretically possible to modify the IMEI by editing the QCN file. quectel change imei
