Removing a SIM card from an iPhone is usually pretty straightforward. First, you’ll need a SIM ejector tool or a small paperclip to gently push into the small hole next to the SIM tray, which is on the side of your iPhone. The tray will pop out, and you can remove or replace the SIM card. How comfortable do you feel with doing this? If you’d like any specific guidance or tips, feel free to ask!
