How to Change the SIM Card in an iPhone

Where to find the SIM tray and what you'll need

The SIM card slot on an iPhone is a small tray on the side of the phone, not inside the battery compartment like older phones. You'll need a SIM ejector tool — a thin metal pin that comes in the box with most iPhones, or you can use a straightened paperclip or a safety pin if you don't have the original tool.

The exact location of the SIM tray depends on your iPhone model. On iPhone 14, 15, and newer models, it's on the right side of the phone. On iPhone 13 and earlier, it's usually on the right side as well, though some older models have it on the left. If you're unsure, look for a small pinhole on the edge of your phone — that's where you insert the tool.

Before you start, power off your iPhone completely. This prevents any interruption to your phone's connection and protects the SIM card slot from accidental damage. You don't need to remove the SIM card to turn off the phone — just hold the power button and volume button together until the "slide to power off" screen appears, then slide to shut down.

Key Takeaways

Locate the SIM tray on the side of your iPhone using the small pinhole, then power off the phone before removing the old SIM card.
Insert the SIM ejector tool (or a straightened paperclip) straight into the pinhole and push gently until the tray pops out.
Lift the tray out completely, remove the old SIM card, and place the new one in the same position with the gold contacts facing down.
Push the tray back in until it clicks, then power your iPhone back on and wait for the carrier signal to appear.
If your new SIM card doesn't work after 10 minutes, turn the phone off and on again, or contact your carrier to confirm the SIM is active.

Removing the SIM tray with the ejector tool

Hold your iPhone firmly in one hand and position the SIM ejector tool perpendicular to the pinhole — this means the tool should be at a 90-degree angle to the phone's surface, not tilted. Push the tool straight into the hole with gentle, steady pressure. You should feel a slight click or resistance, and the tray will begin to pop out.

Do not force the tool or twist it. If the tray isn't moving after light pressure, you may be in the wrong spot. Check your iPhone model again and look for the pinhole on the correct edge. Once the tray starts to come out, remove the tool and use your fingernail or the tool to pull the tray the rest of the way out. The tray should slide out smoothly without resistance.

Removing the old SIM and inserting the new one

The SIM tray has a small indentation or slot where the SIM card sits. Gently lift the old SIM card out of the tray — it should come free without any force. If it's stuck, do not pry at it; instead, try tilting the tray slightly to help the card slide out.

Place your new SIM card into the tray in the exact same position as the old one. The card should sit flat in the indentation with the gold contacts facing downward — this is the side that touches the phone's internal reader. The SIM card will fit snugly but should not require force to seat. If you're using a nano-SIM (the smallest size), make sure it's fully inserted into the slot and not hanging over the edge of the tray.

Reinserting the tray and powering on

Hold the tray level and align it with the slot on the side of your iPhone. Slide the tray back in slowly and steadily until you hear or feel a click — this means the tray is fully seated and locked in place. The tray should be flush with the edge of the phone when it's fully inserted. Do not force it; if you feel resistance, pull it out and check that the SIM card is positioned correctly.

Once the tray is find, power your iPhone back on by holding the power button until the Apple logo appears. Wait for the phone to fully boot up — this usually takes 30 seconds to a minute. You should see your carrier's name appear in the status bar at the top of the screen, along with signal bars. If you see "No Service" or "SOS Only," wait another 10 minutes for the phone to connect to the network.

What to do if the SIM card isn't recognized

If your iPhone still shows no signal after 10 minutes, turn the phone off and on again. Sometimes the phone needs a restart to fully recognize a new SIM card. Power off completely, wait 10 seconds, then power back on and wait another minute for the signal to appear.

If the phone still doesn't recognize the SIM card, check that the card is positioned correctly in the tray — the gold contacts must face downward and the card must be fully seated. Remove the tray again and reseat the SIM card, making sure it's not tilted or partially inserted. If you've tried this twice and the phone still shows no service, contact your carrier to confirm the SIM card is active and properly registered on their network. Sometimes a new SIM needs to be activated by the carrier before it will work.

Switching between two SIM cards on dual-SIM iPhones

Some iPhone models (iPhone 13 and newer) support two SIM cards at the same time — one physical nano-SIM and one eSIM (digital SIM). If you have a dual-SIM iPhone and want to use a second physical SIM card, you'll need to replace the existing one using the same steps above. The phone can only hold one physical SIM at a time, though you can switch between them by removing and reinserting the tray.

If you want to keep both SIM cards active without swapping them in and out, ask your carrier about setting up an eSIM instead. An eSIM is a digital SIM card that you can set up through your phone's settings without opening the physical tray. This lets you use two different carriers or phone numbers on the same iPhone without physically changing anything.

Common mistakes to avoid

The most common error is inserting the SIM card upside down — the gold contacts must face the phone, not the tray. If you see the card sitting with the gold side facing up, remove it and flip it over. Another frequent mistake is using too much force when pushing the ejector tool into the pinhole. The tray should pop out with light pressure; if you're pushing hard, you're likely in the wrong spot or the tool is at the wrong angle.

Do not attempt to remove the SIM tray while the phone is powered on, and do not leave the tray out for extended periods. Dust or debris can get into the slot and cause connection problems. If you drop the tray or the SIM card, inspect both for visible damage before reinserting. A bent SIM card or a tray with a cracked edge may not make proper contact with the phone's reader and will cause "No Service" errors.

Frequently Asked Questions

Can I change my SIM card without turning off my iPhone?

You can technically remove and insert a SIM card while the phone is on, but it's safer to power off first. Removing the SIM while the phone is active can interrupt the connection and potentially cause data loss if the phone is in the middle of a process. Powering off takes 30 seconds and prevents any risk.

What if I lost my SIM ejector tool?

A straightened paperclip, safety pin, or even a thin earring post will work as a replacement. The tool just needs to be thin enough to fit into the pinhole and sturdy enough not to bend under light pressure. Avoid using anything too sharp or thick, as you could damage the pinhole or the tray.

Do I need to do anything in settings after changing the SIM card?

No, your iPhone should recognize the new SIM card automatically once it's inserted and the phone is powered on. The phone will connect to the carrier's network within a few minutes. If you're switching to a different carrier, you may need to contact them to confirm the SIM is active, but you don't need to change any settings in the phone itself.

Why does my iPhone say "SIM not supported" after I insert a new card?

This message usually means the SIM card is not compatible with your iPhone model or carrier. Some older iPhones only work with specific SIM sizes or carriers. Check with your carrier to confirm the SIM card is the correct type for your phone. You can also try removing and reinserting the card to rule out a seating problem.

How long does it take for a new SIM card to work?

Most new SIM cards connect within a few minutes of being inserted. You should see your carrier's name and signal bars in the status bar within 5 to 10 minutes. If it takes longer than 15 minutes, restart the phone. If the SIM still doesn't work after a restart, contact your carrier — they may need to set up the card on their end.
