You can with a sim reader.

If you lose your phone they can just transfer your number to a new sim for you.

Mind you though, SIMs are useless for storage now. Use cloud based contacts so you can add more details, emails, addresses etc.

what if it's a prepaid phone (the kind that uses refill cash cards), can you keep your phone number if you lose it?

If you provided ID to activate it, yes.

Otherwise no way to identify it as yours.
