Why do I have to enter the pin to my SIM after returning from flight mode

[Nordlig]

I set my phone to flight mode every night and each morning, besides the pass code to the phone, I have to enter the pin to my SIM (actually pins to two SIMs). Its an awful lot of pins - cant the SIM pin be saved somehow when I use flight mode? Is it a setting I missed? Having this situation I wont forget the SIM pins, that is for sure

You can deactivate the Sim Code under Settings > Security.

Why you have to do this is because with flight mode you ‘disable’ your SIM card. But, as @timbuktu suggested, turning your SIM PIN-code off should do the trick.

I found the setting and it works perfectly! Thank you @timbuktu and @Robin
