This article is for educational purposes and authorized device management only. Changing an IMEI to bypass legal tracking, evade theft blacklists, or commit fraud is illegal in nearly all jurisdictions (USA, EU, UK, China). You must own the hardware and have a legitimate operational reason (e.g., network whitelisting) to change the IMEI. Part 1: What is an IMEI and Why Do People Want to Change It on Quectel Modules? An IMEI is a 15-digit unique identifier assigned to every cellular device. It is the hardware’s fingerprint to the mobile network. quectel change imei
