2. Insert the SIM card: If you have a physical SIM card, insert it into your iPhone. To do this, use a SIM eject tool or even a paperclip to open the SIM tray on the side of your device.

You can find the model by going into your iPhone's settings, selecting "General" and then opening "About." Once you have found the tray, insert a paper clip or SIM removal tool into the small hole.

This means that if you want to set up a new iPhone, or simply protect your personal information from being stolen while the phone is away, you should take out the SIM card. Luckily, doing so is easy.

To remove the SIM card in your ‌iPhone‌ or iPad, you'll need the SIM eject tool that Apple includes in the device's box. If you don't have one, you can use a regular paper clip.

A SIM card is a small chip that you insert into your phone and allows you to connect to your carrier's network. You can then make phone calls, send messages, and use mobile data through your carrier.
