How to Change Your SIM Card on iPhone

The basic steps to swap SIM cards

To change your SIM card on an iPhone, you need to open the SIM tray on the side of the phone, remove the old card, and insert the new one. The process takes about two minutes and requires only the SIM ejector tool that came in your iPhone box — or a straightened paperclip if you cannot find it.

The SIM tray is a small rectangular slot on the side of your iPhone. On newer models (iPhone XS and later), it is on the right side. On older models, the location varies slightly, but it is always on an edge of the phone. You will see a tiny hole next to the slot.

Push the SIM ejector tool straight into that hole with gentle, steady pressure. The tray will pop out slightly. Pull it the rest of the way out with your fingers. The old SIM card sits in a small indent in the tray — lift it out and set it aside. Slide your new SIM card into the same indent, making sure the gold contacts face downward and the cut corner of the card lines up with the cut corner of the tray.

Key Takeaways

The SIM tray is on the edge of your iPhone and opens with the SIM ejector tool or a paperclip pushed into the small hole next to it.
The SIM card slides into the tray with the gold contacts facing down and the cut corner matching the tray's cut corner.
Push the tray back in until it clicks — you should feel and hear a small snap when it is fully seated.
Your iPhone will recognize the new SIM card within a few seconds; if it does not, restart the phone by turning it off and back on.

Inserting the tray back into your phone

Once the new SIM card is in the tray, hold the tray level and slide it back into the slot on the side of your phone. Push it in slowly and steadily until you feel it click into place. You should hear a small snap and feel the tray seat flush with the edge of the phone. Do not force it — if you meet resistance, pull it out and check that the SIM card is sitting flat in the indent.

Your iPhone will recognize the new SIM card within a few seconds. You may see a message asking you to enter your PIN (a security code your carrier provided with the SIM card). If the phone does not recognize the card after 30 seconds, restart your iPhone by holding the power button until the shutdown screen appears, then slide to power off. Wait 10 seconds and turn it back on.

What to do if your iPhone does not recognize the new SIM

If your iPhone still does not recognize the SIM card after a restart, the card itself may be damaged, or the tray may not be fully inserted. Remove the tray again and inspect the SIM card for cracks, bends, or dirt on the gold contacts. If the contacts are dirty, wipe them gently with a soft, dry cloth.

Check that the card is sitting completely flat in the tray indent and that the cut corner is aligned correctly. Reinsert the tray and restart the phone again. If the problem persists, contact your carrier — they can confirm whether the SIM card is active and send you a replacement if it is faulty.

Differences between physical SIM cards and eSIM

Newer iPhones (iPhone 13 and later) can use an eSIM, which is a digital SIM card stored in your phone's software rather than a physical card. If your carrier supports eSIM, you can add a second line to your iPhone without opening the SIM tray at all.

To set up an eSIM, go to Settings, tap Cellular, then tap Add Cellular Plan. Your iPhone will guide you through scanning a QR code or entering information your carrier provides. You can have both a physical SIM card and an eSIM active at the same time on newer iPhones, which is useful if you travel or need two phone numbers.

If you are switching to eSIM and no longer need your physical SIM card, you can remove it from the tray and keep the tray empty. The phone will continue to work with the eSIM alone.

Before you remove your old SIM card

Before you swap SIM cards, contact your current carrier and ask them to deactivate the old card. This prevents someone else from using it and protects your account. Most carriers can do this over the phone or through their website in a few minutes.

If you are switching to a new carrier, they will usually set up your new SIM card remotely once you insert it. You may need to restart your phone for the set up to complete. If you are keeping the same carrier and just replacing a damaged card, they will transfer your phone number and service to the new card automatically.

Troubleshooting a stuck SIM tray

If the SIM tray will not pop out, do not force it. The ejector tool should require only light pressure — if you are pushing hard, you may damage the tray or the phone.

Make sure you are pushing straight into the hole, not at an angle. If the tool keeps slipping, try a straightened paperclip instead — it may grip the hole better. If the tray still will not budge, it may be stuck due to debris or corrosion. Try again in a few minutes, or contact Apple Support for help.

What happens to your data when you change the SIM card

Changing your SIM card does not affect any of your data — your photos, messages, contacts, and apps all stay on your phone. The SIM card only stores your phone number and carrier information. Your iPhone backs up everything else to iCloud or your computer, depending on how you have it set up.

When you insert a new SIM card, your phone number and carrier service will change to match the new card, but all your personal data remains exactly as it was. You will not lose anything by swapping SIM cards.

Frequently Asked Questions

Do I need to turn off my iPhone before removing the SIM card?

No, you can remove and insert the SIM card while your iPhone is on. The phone will not be harmed. However, you may want to turn it off if you are nervous about the process — it does not hurt, and it gives you time to work without the phone trying to connect to a network.

What if I lose my SIM ejector tool?

A straightened paperclip works just as well. You can also use a small safety pin, a thin earring, or the tip of a sewing needle. The hole is small, so the tool needs to be thin and pointed. Avoid anything too thick or too sharp that might slip and scratch your phone.

Can I use a SIM card from a different carrier in my iPhone?

Yes, as long as your iPhone is not locked to a specific carrier. Most iPhones sold in the United States are unlocked and will work with any carrier's SIM card. If your phone is locked, contact your original carrier and ask them to unlock it — this is usually free once your contract is complete.

How long does it take for my iPhone to recognize a new SIM card?

Usually a few seconds to a minute. Your iPhone will display the carrier name at the top of the screen once it recognizes the SIM card. If it takes longer than two minutes, restart your phone.

Will changing my SIM card change my phone number?

Only if the new SIM card belongs to a different carrier or a different account. If you are replacing a damaged SIM card with a new one from the same carrier and account, your phone number stays the same. Your carrier will transfer your number to the new card automatically.
