Why do I get +QLWREG: 1

I have a BC66 module and I am sending commands to set connect to the network and set the PSM and do nothing else It all works fine, but I get +QLWREG: 1 when its running. I read about it and I am not using the LwM2M,so why do I get this?

BC66 connects to lwM2M protocol by default, so the corresponding URC will be returned after the module registers the network. +QLWREG: 1 indicates that LWM2M is not registered, you do not need to worry about the use of other application protocols.
