Like, I lost my sim card. I’m sure it’s somewhere in my home. I have a ton of old phones. When I call the number it says switch off, I wanna know if it’s the same even if the sim is outside of a mobile? How does it all work.

If you let your provider switch it off it will be deleted in their systems. When you just take it out of the phone the system will still know that it is active and just not connected currently.
A Sim card is nothing else but an ID. Provider system checks sims against a list. If its not on the list, its switched off.
