, the IMEI is managed via AT commands through a serial port connection. Querying the IMEI : The command is standard for retrieving the current 15-digit identifier. Modification Command : Some users have successfully used the command AT+EGMR=1,7,"[NEW_IMEI]" to overwrite the identifier. Software Requirements
Quectel Wireless Solutions manufactures some of the most popular LTE, 5G, and GNSS modules used in IoT devices, routers, and CPE (Customer Premises Equipment). Occasionally, users or developers seek to change the International Mobile Equipment Identity (IMEI) of these modules, often to bypass network restrictions on IoT data plans, allow specific devices to run on consumer cellular plans, or for testing purposes.
Before attempting to read or modify any internal parameters of a Quectel module, you must establish a stable serial connection. 1. Hardware Requirements
Before diving into the technical methods, a crucial disclaimer: This article is provided for educational and informational purposes only. Readers are strongly advised to consult local telecommunications regulations before attempting any modification described herein.
In regions like the United States (under the Mobile Device Theft Prevention Act), the United Kingdom, and the European Union, changing an IMEI string is a criminal offense punishable by fines and imprisonment. quectel change imei
While rare, legitimate IMEI modification scenarios exist:
AT+CGSN AT+GSN AT+EGMR=0,7
set to the module's "AT Port" (often at a baud rate of 115200). Manufacturer Position Quectel officially states that customers are not allowed to modify the IMEI. Support Policy
Most EU member states prohibit IMEI tampering under telecommunications fraud statutes. The general principle: modifying the IMEI is considered a crime because it can be used to pass off stolen phones as legitimate or to evade blocks imposed by telephone companies or authorities. , the IMEI is managed via AT commands
In underground technical forums and among some developers, the phrase “Quectel change IMEI” has gained notoriety. It refers to the process of overwriting the factory-programmed IMEI with a different number. Despite the availability of tools and commands to do so, the practice is illegal in most jurisdictions unless explicitly authorized (e.g., by a network operator for certified repairs). This paper clarifies the technology behind IMEI modification, distinguishes legitimate from malicious intentions, and outlines security best practices.
The following outline is provided for understanding the process.
Modifying the IMEI on a Quectel module generally involves interacting with the baseband processor via serial interfaces (UART/USB). The complexity varies depending on the module series (e.g., BG96, EC25, M10).
There are several reasons why you might need to change the IMEI on a Quectel module: 3. Hardware-Specific Considerations
AT*PROD=0
A: Yes. Any modification to the module’s identity information voids the manufacturer’s warranty.
For the changes to commit and register on the cellular baseband, cycle the power or issue a soft reset command: AT+CFUN=1,1 Use code with caution. 3. Hardware-Specific Considerations
