Quectel Ec25 Change Imei [2021]

Ensure your hardware setup supplies adequate current. The EC25 can pull spikes of up to 2A during network registration and reboots. A standard computer USB 2.0 port (limited to 500mA) may cause the module to brown out and reset continuously.

The module will return a 15-digit number representing your current IMEI, followed by OK . Step 4: Write the New IMEI

Searching for the phrase typically leads to fragmented information: half-working AT commands, warnings about legal issues, or outdated firmware guides.

Quectel provides an extended proprietary command structure via AT+EGMR to write an alternate IMEI into the device's secondary configuration sector. AT+EGMR=1,7," " Use code with caution. Example Execution quectel ec25 change imei

A Quectel EC25 module (e.g., EC25-A, EC25-E, EC25-V, etc.) mounted on a PCIe development board or connected via a USB-to-UART adapter.

While altering hardware identifiers is a standard practice in closed-loop lab environments and compliance testing facilities, executing it on public networks carries substantial risks. 1. Legal and Regulatory Violations

In many countries, changing a device's IMEI to evade cellular blocks or spoof cellular identity on public commercial networks is illegal. Ensure you are performing this action in a controlled lab environment or for legitimate development purposes. Ensure your hardware setup supplies adequate current

If the module stops responding after a reboot, check your host computer's Device Manager. The USB endpoints may have re-enumerated under different COM port numbers.

AT+CFUN=1,1

Sometimes, a specialized network is hardcoded to only accept a specific range of IMEIs. If a technician needs to replace an old, broken module with a modern EC25, they might attempt to "clone" the old identity to keep the system running without a total software overhaul. The module will return a 15-digit number representing

Before reading this guide, you must understand that changing the IMEI (International Mobile Equipment Identity) of a cellular modem is illegal in many jurisdictions (including the USA, UK, EU, and China) if done to bypass tracking, evade carrier blacklists, or cover up stolen hardware. This article is for educational purposes only —specifically for developers testing prototype hardware, resetting development modules to default, or cloning a legally owned IMEI from a damaged module to a replacement under the same license agreement. Proceed at your own risk.

Issue the AT+EGMR command to write your new IMEI. Replace your_new_15-digit_IMEI_here with the actual number you have permission to use.
