On most iPhones, the SIM card is in a small tray on the side of the phone, but newer U.S. iPhone 14/15 models use eSIM only and have no physical SIM tray at all.

Physical SIM tray location

For iPhones that still use a physical SIM card (iPhone 13 and earlier worldwide, and many non‑US iPhone 14/15 models):

  • The SIM tray is on the side of the phone as a thin rectangular slot.
  • You’ll see a tiny round hole next to the tray where you insert a SIM eject tool or straightened paper clip to pop it out.
  • On most recent models (iPhone X and later), the tray is on the right edge when you’re looking at the screen.

How to open it (quick steps)

  1. Power off your iPhone (recommended but not required).
  2. Find the small hole next to the thin tray on the side of the phone.
  1. Gently push a SIM tool or paper clip straight into the hole until the tray pops out.
  1. Pull the tray out, check or replace the SIM, then slide the tray back in the same way it came out.

If your iPhone has no SIM tray

  • Some newer iPhones sold in certain regions (like the U.S. iPhone 14/15) use eSIM only , so there is no physical SIM card slot anywhere on the device.
  • In that case, your “SIM” is digital and managed in:
    • Settings → Mobile Data / Cellular → SIMs or eSIM settings.

If you just want SIM info (not the card itself)

If you only need SIM details (number, carrier, etc.) and not the physical card:

  • Go to Settings → Mobile Data / Cellular.
  • Tap your SIM/eSIM and view its information there.

TL;DR:

  • Look for a thin tray with a pin hole on the side of your iPhone; that’s where your SIM card sits.
  • If your phone has no tray at all, it likely uses eSIM, so everything is in Settings under Cellular/Mobile Data.
