NETGEAR MR6500 AT command error

[Mysteryhero]

I have a Netgear mr100 that i changed imei a few months ago. I just got Mr6500, tried to do the same, and got this error. Did a bit of research and now I found out its not supported. Please I would like to have my credit back on my account and hold it on for when or if it gets supported. I might probably return this and got something old that guarantee to work .
