Hello. I want the same, how the question from Option not to remember pin after the factory reset? for higher security. In my case for an TRB500 modem. Is a Custom script*, an solution? But exist a event in the case of Factory reset is starting? And then what is the command to set SIM PIN on zero or none?

Under https://wiki.teltonika-networks.com/view/TRB500_Device_Recovery_Options#Factory_reset stand

Additional note: SIM PIN on the main SIM card is the only user parameter that is kept after a factory reset.

* = TRB500_Custom_Scripts.

Thank you for taking note that.

See here - when you run firmware 07.07.1 and greater, SIM pin will be safely deleted when using the reset button.
And only reset button!

Hello,

I recommend updating your TRB500 to the newest firmware version, TRB500_R_00.07.07.1. This update allows you to choose whether to reset the router with PIN and some other settings saved, or to fully reset it to defaults when completing a factory reset.

Best Regards,
