While not officially documented for consumer use, several technical forums cite specific AT commands for "repairing" or modifying the IMEI, particularly on devices like the PinePhone or GL.iNet routers using EC25 modems:
Replace 123456789012345 with your target 15-digit IMEI number. AT+EGMR=1,7,"123456789012345" Use code with caution.
echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2
Searching for the phrase typically leads to fragmented information: half-working AT commands, warnings about legal issues, or outdated firmware guides. quectel ec25 change imei
If the IMEI resets back to original factory parameters upon power-cycling, the module firmware might possess an OTP (One-Time Programmable) secure lock or secure boot enabled by the hardware integrator.
Configuring the Access Point Name ( AT+QICSGP ) to ensure connectivity.
Your new 15-digit IMEI.

Connect your EC25 device to your computer via USB. Open your computer's Device Manager. Under "Ports (COM & LPT)", look for the "Quectel USB AT Port". Note the COM port number (e.g., COM3 on Windows) or the device path (e.g., /dev/ttyUSB2 on Linux).
Networks cache IMEIs. To confirm the new IMEI is active on the live network, force a re-attach: While not officially documented for consumer use, several
Before proceeding, you must understand the legal implications of changing an IMEI:
After extensive testing across EC25E, EC25A, EC25V, and EC25-MiniPCIe variants, only two practical methods exist. Neither is officially documented by Quectel.
