IMEI modification on EG25G

IoT Modules LTE Standard Module
1

Hello.

I have a device with the EG25-G modem, software version EG25GGCR07A02M1G.

I have tried to modify the IMEI with AT commands but the process fails.

The command I use is:

AT+EGMR=1,7,“new_IMEI_number”

I wonder what I am doing wrong, or if I need to change to another firmware that supports the necessary command?

Thank you.

First of all, it is not allowed for the customer to modify the IMEI of the module. Quectel cannot guarantee that it works if modify the IMEI or after the IMEI.

Maybe my question wasn’t clear.

Quectel would not provide any command to modify the IMEI.
Does it shows CME error? Please check the IMEI you set.

Solved.

On my device, the AT command is successful only when the modem interface is in a certain condition - and the interface is not up, or not fully up, while my particular device is also connected to WAN via Ethernet. The solution was to disconnect the WAN Ethernet cable and have the modem up and connected while entering the AT command.
