How to Change and Install a New IMEI on Quectel Modules: A Complete Technical Guide

Introduction

Quectel is one of the world’s leading suppliers of IoT modules, including the popular EC25, EG95, BG96, and UC20 series. These modules are widely used in routers, tracking devices, and industrial gateways. However, a common challenge faced by system integrators and developers is the need to change or install a new IMEI (International Mobile Equipment Identity) number on a Quectel module.

To change the IMEI on a Quectel modem, you typically use specific AT commands through a terminal interface. While Quectel does not officially document or support this feature for general users, it is often possible using the AT+EGMR command, which is frequently used for "repairing" or setting the identifier on modules like the EG25-G. Prerequisites & Installation

Changing the IMEI on a Quectel module can have risks and considerations: quectel change imei install

QCN Backup: Professional engineers often use the Quectel NV Item Manager to back up the QCN file. If an IMEI "install" fails, the QCN can be edited and reflown back into the module using QPST.

The module must now report the new IMEI. Also check with: How to Change and Install a New IMEI

Confirm the Result: If successful, the module will return an OK response.
