Imei: Quectel Change

Changing an International Mobile Equipment Identity (IMEI) number on a Quectel module is a technical process typically performed for development, testing, or restoration purposes. While the IMEI is a unique 15-digit identifier designed to be permanent, certain scenarios—such as repairing a corrupted NVRAM or testing network behavior in a lab—require modification. Understanding the IMEI

To make this a "solid" feature, it must include safeguards to prevent accidental bricking or illegal use: quectel change imei
