Do I remove my SIM card from old phone

Hello!

Please see the image I attached. On the left side of your iPhone is a small hole into which you can put a sim tool which was included inside the iPhone box on models before iPhone 14 as that one is ESiM only.

If you are selling to trading your phone, yes, you remove the sim card. But if you are buying a new iPhone, you will want to set it up using eSim as opposed to a physical sim, assuming your carrier supports eSim.
