What will happen if I take my sim out of my iPhone 5

Hey so I want to change my number and just get a new sim over all… If I take my sim out of my phone will I lose anything? Because my iPhone icloud storage has been full for a whole so some of the stuff isn't backed up so I was wondering if I change sim will I lose pictures etc?

You will turn into a brick.

Sim cards only hold contacts… And that is IF you CHOOSE to save your contacts on the simc ard or the phone…

everything else is saved on the phone

Everything will remain on your iPhone as long as you don't physically go in and delete it.

Nothing will change. Except contacts might be missing if they were saved onto the sim
