Inspect the 15-digit response string. If the installation succeeded, the terminal output will show the new identifier rather than the original factory number.
The International Mobile Equipment Identity () serves as the universal fingerprint for cellular hardware. For network administrators, engineers, and IoT developers working with Quectel wireless modules (such as the EC25, EG25-G, or RM502Q), understanding how to read, restore, or modify this identifier is critical for deep testing, regulatory alignment, or hardware recovery.
In many countries (including the US, UK, and EU), changing a device's IMEI is illegal or strictly regulated to prevent fraud and theft.
is a multi-step process involving driver installation, diagnostic mode entry, and using specialized tools like QFirehose, QDM, or AT+EGMR. While it is a valuable capability for integrators and developers, it carries legal responsibilities.
Plug in your module via USB and open . You should see several new ports under "Ports (COM & LPT)": Quectel USB AT Port (Used for sending commands) quectel change imei install
The official Quectel USB serial driver package installed on your operating system.
Quectel modules (e.g., EC20, EC25, BG96) store the IMEI in a Non-Volatile Memory (NVRAM) partition.
Apply the modification command sequence required by that specific firmware line: AT+QIREG="IMEI","YOUR_NEW_15_DIGIT_IMEI" Use code with caution. Step 4: Commit Changes and Reboot the Module
Wait for the module to power off.
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 (International Mobile Equipment Identity) number on a Quectel module.
For Quectel modules built on non-Qualcomm chipsets (such as certain BG95 or standard IoT variants):
Send the following command, replacing new_15_digit_imei with your desired number: AT+EGMR=1,7,"new_15_digit_imei" Use code with caution.
To help you troubleshoot any specific roadblocks with your deployment, could you share: Inspect the 15-digit response string
: Install a serial port tool like PuTTY or MobaXterm to send commands to the module.
Network operators utilize databases like the Central Equipment Identity Register (CEIR) to blacklist cloned or invalid IMEIs.
