Changing a cellular module's International Mobile Equipment Identity (IMEI) is a specialized process often required during hardware prototyping, cellular network testing, or device repair. This technical guide outlines how to interface with Quectel modules, establish AT command communication, and flash necessary firmware or identifiers.
This is a more advanced method, primarily used for disaster recovery rather than casual modification. A file is essentially a full backup of the module's non-volatile memory, including its calibration data, serial numbers, and IMEI.
The module firmware may have locked security sectors. You need to upgrade or downgrade to an engineering firmware version that permits identity configuration.
Quectel modules utilize specific AT commands to read and overwrite identification numbers stored in the module's non-volatile memory (NVRAM). Follow these steps systematically. Step 1: Connect and Verify Communication quectel change imei install
The module is actively trying to communicate with a SIM card or registered network. Run AT+CFUN=0 to turn off the radio functionality completely before trying to overwrite the IMEI.

Quectel is a leading provider of wireless communication modules, widely used in various industries such as IoT, industrial automation, and smart cities. One of the key features of Quectel modules is the ability to change the IMEI (International Mobile Equipment Identity) number, which is a unique identifier assigned to each mobile device. In this article, we will explore the process of changing the IMEI on Quectel modules, the reasons behind it, and the benefits it offers.

For Quectel modules built on non-Qualcomm chipsets (such as certain BG95 or standard IoT variants): A file is essentially a full backup of
Run AT+GSN again to confirm the modem reflects the new number.
Disclaimer: Changing an IMEI may be legally restricted or illegal in certain jurisdictions depending on local telecommunications laws. Ensure you comply with all local regulations before proceeding. 1. Hardware and Software Prerequisites
Method A: Standard Quectel Production Command (Qualcomm Chipsets) Quectel modules utilize specific AT commands to read
To legitimately modify the IMEI (for instance, to configure a custom hardware setup approved by your cellular provider), you must generally go through the following steps with the manufacturer:
