Auto register to network disable

Technical Subjects Software General Function

Hi all,

Is there an opportunity to disable the auto register to network and only enable if I really need it, to save power? I use the BC660K.

hi,patrech:
you can execute:

at+cfun=0

re-boot module:

at+cfun=1

at+cfun=0 looks like not saved to non-volatile memory. After reset, modem starts again registration immediately.
Is it possible to boot modem to cfun=0 by default after power-up ?
