Where the SIM card slot is and what you need

The SIM card slot on an iPhone is a small tray on the side of the phone. On newer iPhones (iPhone XS and later), it is on the right side. On older models, the location varies—check your phone's manual if you are unsure. You will need a SIM ejector tool, which is a thin metal pin that comes in the box with your iPhone. If you have lost it, a straightened paperclip or a small safety pin works just as well.

Before you start, power off your iPhone completely. This is not strictly required, but it prevents any accidental data loss or damage to the phone's systems while the tray is open. You do not need to remove the SIM card from your old phone first—you can do that after you have the new one ready.

Key Takeaways

  • The SIM card slot is a small tray on the side of your iPhone, and you open it by inserting a SIM ejector tool (or paperclip) into the tiny hole next to the slot.
  • Push the tool straight in until the tray pops out, then lift the tray gently and remove the old SIM card by sliding it out.
  • Insert the new SIM card into the tray with the gold contacts facing down and the notched corner matching the tray's shape, then push the tray back in until it clicks.
  • After reinserting the tray, power your iPhone back on and wait for it to recognize the new SIM card, which usually takes a few seconds to a minute.
  • If your phone does not recognize the new SIM card, restart the iPhone or contact your carrier to confirm the SIM is active.

How to eject the SIM card tray

Locate the small hole next to the SIM card slot on the side of your iPhone. Insert the SIM ejector tool (or paperclip) straight into this hole and push gently but firmly until you feel resistance. You should not have to force it—if it feels stuck, you are likely in the wrong hole or at the wrong angle.

Once you push in the tool, the tray will pop out slightly. Remove the tool and gently pull the tray all the way out using your fingernail or the edge of the tool. The tray is small and straightforward to drop, so do this over a table or surface where you can see it clearly.

Removing the old SIM card and inserting the new one

The SIM card sits in a small slot on the tray. Slide it out gently—it should come free without much resistance. If it feels stuck, do not force it; instead, check that you are sliding it in the correct direction (usually toward the edge of the tray, away from the center).

Take your new SIM card and orient it so the gold contacts face downward. The card has a notched corner; this notch must align with the notch in the tray. Slide the new card into the slot until it sits flat and flush with the tray. The card should not stick up or sit at an angle.

Reinserting the tray and powering on

Hold the tray level and slide it back into the slot on the side of your iPhone. Push it in gently until you hear or feel a click—this means the tray is fully seated. Do not force it; if it does not slide in smoothly, remove it and check that the SIM card is positioned correctly.

Once the tray is back in place, power your iPhone back on by holding the side button (or top button on older models) until the Apple logo appears. Wait for the phone to fully boot up. Your carrier's name should appear in the status bar at the top of the screen within a few seconds to a minute, which means the SIM card has been recognized.

What to do if the phone does not recognize the new SIM card

If your iPhone shows "No SIM" or "SIM Not Supported" after you power it on, first try restarting the phone. Hold the side button and either volume button until the power-off slider appears, then slide to power off. Wait a few seconds, then power the phone back on.

If the message persists, the SIM card may not be active yet. Contact your carrier to confirm the SIM has been activated and is compatible with your phone. Some carriers require you to set up a new SIM through their website or app before it will work. If you are switching carriers, make sure the new SIM is for the correct carrier and that your account is set up with them.

Differences between physical and eSIM

Newer iPhones (iPhone XS and later) support both a physical SIM card and an eSIM, which is a digital SIM stored on the phone itself. If your carrier offers eSIM, you can set it up through the Settings app without opening the physical SIM slot. Go to Settings > Cellular > Add Cellular Plan and follow the prompts.

You do not have to use both at the same time. Many people use the physical SIM for their main carrier and the eSIM for a second line or a carrier they use while traveling. If you want to use only eSIM and remove the physical SIM entirely, you can leave the tray empty—the phone will still work on the eSIM alone.

Common mistakes to avoid

The most common error is inserting the SIM card upside down. The gold contacts must face downward into the tray. If you insert it with the contacts facing up, the phone will not recognize it. Remove the tray and flip the card over.

Another mistake is not aligning the notched corner of the SIM card with the notch in the tray. The card will not sit flat if the corners do not match, and the tray may not close properly. Before reinserting the tray, double-check that the card is flush and level.

Do not force the tray back in if it feels stuck. If it does not slide smoothly, remove it and inspect the SIM card position again. Forcing the tray can damage the slot or the card itself.

Frequently Asked Questions

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

Technically yes, but it is safer to power off first. Removing the SIM while the phone is on can occasionally cause errors or data loss. It takes only a minute to shut down and restart, so it is worth doing.

What if I lose my SIM ejector tool?

A straightened paperclip, a small safety pin, or even a thin needle will work. The tool just needs to be small enough to fit in the hole and firm enough not to bend. Avoid anything too sharp that could slip and scratch your phone.

Do I need to remove my phone case to access the SIM slot?

Most phone cases have a cutout for the SIM slot, so you should not need to remove the case. If your case covers the slot, you can either remove the case or carefully peel it back just enough to access the hole. Check your case's design first.

Will changing my SIM card erase my data?

No. Your photos, messages, apps, and settings are stored on the phone itself, not on the SIM card. Changing the SIM only changes which carrier's network your phone connects to. Your data remains untouched.

How long does it take for the new SIM to work after I insert it?

Usually a few seconds to a minute after you power the phone back on. If it takes longer than five minutes, restart the phone or contact your carrier to confirm the SIM is active.
