GL -X3000 Spitz AX IMEI won’t update

I have a new GL-X3000 Spitz AX router that I’m trying to change the IMEI number. I’ve entered the manual command but it does not update. Any help would be greatly appreciated I’m trying to use an AT& T sim from my IPad.

What result do you get by executing the AT command?

It’s says error

You used AT+EGMR=1,7,"012345678901234" where 012345678901234 is your new IMEI?

AT+EGMR=1,7,"861585040740945"
This is the command I used but with my IMEI

Please make sure your IMEI is 15 digits long. Is this the case?

Yes, it is if characters long

Please try to write the command and don't copy it. Make sure you use " instead of

Still no change

What IMEI do you want to use? I mean, where does it come from?

It comes from an Apple ipad

Can you check that the IMEI is a correct one by using an online service like https://imei24.com/?
Please make sure to turn off your GSM module in your iPad before trying to set the modem IMEI.
