Quectel Change Imei Jun 2026

Modules based on ASR or Spreadtrum chipsets—commonly found in portable Wi‑Fi hotspots and some 5G CPEs—use a different set of commands. These devices often require entering a before the IMEI can be written.

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

Users should be aware that a factory reset may revert IMEI changes. One user documented that "The IMEI check returns the new one but once AT+QCFG='ResetFactory' is called my previously used IMEI is restored" . The restoration uses the original IMEI stored in the module's base configuration, not the donor's XQCN IMEI. quectel change imei

Ensure the Quectel USB drivers are correctly installed. In Windows Device Manager, look for the entry labeled Quectel USB AT Port .

: After application, use AT+CGSN or AT+GSN to verify the change. Modules based on ASR or Spreadtrum chipsets—commonly found

: You must provide your location, the purpose of the change, and your email address.

The real culprit? A grey-market reseller had bought returned units, used a PC utility and AT commands ( AT+EGMR=... ) to overwrite the IMEIs on the Quectel modules, and resold them. They hadn’t just changed numbers — they’d broken the law and poisoned Aisha’s entire dataset. The IMEI is stored in: Users should be

Modifying an IMEI is subject to heavy legal penalties in many global jurisdictions. Before exploring any technical methods, it is crucial to understand the regulatory landscape. The Legitimate Use Cases

A tutorial from telecomHall outlines a straightforward process:

The file contains device-specific calibration data and identifiers, including the IMEI. Using Qualcomm tools like QPST/QFIL, it is theoretically possible to modify the IMEI by editing the QCN file.

Before attempting changes, use these standard AT commands to query current module information: : AT+GSN or AT+CGSN=1 . Get Manufacturer : AT+CGMI . Get Model : AT+CGMM . Get Firmware Version : AT+CGMR . 3. Community-Reported Methods (Unverified)
