Quectel Ec25 Change Imei [cracked] -

The new IMEI must appear.

AT+COPS=?

Your new 15-digit IMEI.

Engineers often use the AT+EGMR command, which is a standard interface for managing mobile equipment identifiers. For example, the command AT+EGMR=1,7,"[NEW_IMEI]" is frequently cited in technical documentation as the method to write a new identifier to the module's firmware.

Test the connection by typing AT and pressing Enter. The module should respond with OK . Step 2: Verify the Current IMEI

The Quectel EC25 uses the Qualcomm platform. The commands used to read and, sometimes, alter modem parameters are standard Qualcomm AT commands.

You cannot simply type 15 random numbers. An IMEI is validated by the Luhn algorithm (Mod 10). If you write an invalid IMEI, the modem may accept it, but the cellular tower will reject the registration request (Location Update Reject).

This is the most common error when using AT+EGMR .

Not all firmware versions expose the same method. If the above fails, use the factory tool: or QPST with Quectel’s secure IMEI writing command.
