Quectel Change Imei Work 💫

The overwhelming consensus from Quectel, community forums, and legal perspectives is . The potential consequences—network failure, a bricked device, a voided warranty, and legal trouble—far outweigh any perceived benefits.

An important nuance: Some countries require "Modem" IMEI ranges rather than "Phone" IMEI ranges for IoT modules. The Quectel EG25-G module uses "Phone" IMEI numbers by default, which can cause registration problems and potentially violate local regulations. This compliance gap drives some legitimate modification needs.

That said, modifying an IMEI is a legally sensitive operation. In many jurisdictions, altering the unique identifier of a cellular device without proper authorization is illegal and can lead to severe penalties. Quectel itself does not officially endorse or support IMEI changes, and the relevant AT commands are not publicly documented. This guide is provided for . You assume full responsibility for any legal or technical consequences that may arise from following these procedures. quectel change imei

Quectel modules use Qualcomm or ASR basebands. The IMEI is stored in:

These factory commands are highly device‑specific. Using them on a module that does not support them may cause unpredictable behavior or permanently damage the module.

The International Mobile Equipment Identity (IMEI) is the unique 15-digit serial number assigned to every cellular device, including the high-performance modules manufactured by . While this number is typically permanent, certain technical scenarios—such as repairing a corrupted parameter partition or ensuring regional compliance—may require modifying it. The Quectel EG25-G module uses "Phone" IMEI numbers

To send these commands, you must connect to the module's using a serial communication tool like PuTTY, MobaXterm, or Quectel's proprietary tools. In many jurisdictions, altering the unique identifier of

Carriers maintain IMEI databases. If two modules broadcast the same IMEI simultaneously on the same network, the carrier may blacklist both devices permanently.

: If a firmware flash goes wrong and corrupts the NVRAM, the IMEI might show as "000000000000000," preventing the device from registering on a network. Restoring the original IMEI is a common fix. IoT Development

This process overwrites the sys_rev partition with a purposefully broken one, writes a new IMEI, calculates its CRC, and flashes to the EFS area.
