As I understand it, the SIM card stores all your data such as contacts, pictures, et al. You can set your phone to store all data on your phone via the SIM card, or in the cloud. If you remove the SIM card from one phone with all the data and insert it into another phone, you should be able to access that data on the second phone but not the original phone since you removed the storage on the SIM card.
I’m not sure that’s a perfect answer.
Nothing in my life is perfect, so I'll give it a try.
