Where the SIM slot is and what you need to open it
The SIM slot on an iPhone is a small tray on the side of the phone that holds your SIM card — the chip that connects your phone to your carrier's network. You open it with a tool called a SIM eject tool, which is a thin metal pin. Apple includes one free with every iPhone in the box, though many people lose it. If you don't have the original, a straightened paperclip works just as well.
The location of the SIM slot depends on your iPhone model. On newer iPhones (iPhone XS and later), it's on the right side of the phone. On older models, it may be on the right or left side. Look for a small hole about the size of a ballpoint pen tip — that's where you insert the eject tool.
Before you open the slot, power off your iPhone completely. This isn't strictly required, but it's the safest approach and takes only a few seconds. Go to Settings, tap General, scroll down, and tap Shut Down, then slide to power off.
Key Takeaways
- The SIM slot is opened with a thin metal pin called a SIM eject tool, which Apple includes in the box or can be replaced with a straightened paperclip.
- The slot is located on the side of your iPhone — usually the right side on newer models — and marked by a small hole.
- Power off your iPhone before opening the SIM slot to avoid any potential issues with the phone's connection.
- Push the eject tool straight into the hole with gentle, steady pressure until the tray pops out; do not force it or push at an angle.
- The SIM card sits in a small notch on the tray and can be removed by gently lifting it out, then reinserted by placing it back in the same notch.
How to insert the eject tool and open the tray
Hold your iPhone firmly in one hand. With your other hand, take the SIM eject tool (or straightened paperclip) and locate the small hole on the side of the phone. The hole is usually surrounded by a tiny circle or oval marking on the phone's frame.
Insert the tip of the eject tool straight into the hole. Use gentle, steady pressure — do not force it or push at an angle. You should feel a slight resistance, then the tray will pop out slightly. If nothing happens after a few seconds of gentle pressure, you may have the wrong location. Check your iPhone model number in Settings (General > About) and look up the correct slot location online.
Once the tray begins to pop out, use your fingernail or the edge of the tool to gently pull the tray the rest of the way out. The tray will slide out completely and you'll see a small notch or slot where the SIM card sits.
Removing and reinserting your SIM card
The SIM card is a small rectangular chip, usually gold or silver in color. It sits in a notch on the tray and is not glued down — it straightforward rests there. To remove it, gently lift one corner of the card with your fingernail and slide it out of the notch.
If you're replacing the SIM card with a new one, make sure the new card is the correct size for your iPhone. Most newer iPhones use a nano-SIM, which is the smallest standard size. If you're unsure, contact your carrier — they can tell you what size you need and may provide a replacement card at no cost.
To reinsert the SIM card, line it up with the notch on the tray so the cut corner of the card matches the cut corner of the notch. Gently slide the card into place until it sits flat. Then slide the tray back into the phone until it clicks and sits flush with the side of the phone.
What to do if the tray won't open
If you've applied gentle pressure and the tray still won't budge, stop and try a different approach. The most common reason the tray won't open is that you're pushing in the wrong location. Double-check your iPhone model and look up the exact slot location — it varies by year and model.
Another reason is that the hole may be blocked by dirt or lint. Use a clean, dry cloth to wipe around the hole, then try again. If the phone is very new, the tray may straightforward be tight. Wait a moment and try once more with steady, gentle pressure.
If the tray still won't open after several attempts, do not force it. Forcing the tool can damage the internal mechanism or break the tool itself. Contact your carrier or visit an Apple Store — they have the proper tools and can open the slot without risk of damage.
Dual SIM iPhones and which slot to use
Some iPhone models (iPhone XS and later) support dual SIM, meaning they can hold two SIM cards at once. These phones have two separate trays or one tray with two slots. If your phone has dual SIM, both slots work the same way — you open them with the eject tool in the same location, and the tray will have space for two cards.
If you're setting up dual SIM for the first time, your carrier can walk you through which slot to use and how to configure your phone to use both cards. Some people use one slot for a work number and one for personal, or one for a home carrier and one for international travel.
Troubleshooting after you've opened the slot
After you've inserted your SIM card and closed the tray, power your iPhone back on. It may take a minute or two to connect to the network. If you see "No Service" after five minutes, try these steps: first, make sure the SIM card is fully inserted and the tray is completely closed. Second, restart the phone by powering it off and back on. Third, go to Settings > General > Reset and tap Reset Network Settings — this clears out old network information and forces the phone to reconnect.
If you still see "No Service" after these steps, the SIM card itself may be damaged or your carrier may need to set up it. Contact your carrier's support line — they can check whether the card is active and whether there are any issues on their end.
Frequently Asked Questions
Can I use a regular paperclip instead of the SIM eject tool?
Yes. A straightened paperclip works just as well as the official tool. The key is that it needs to be thin enough to fit in the hole and sturdy enough not to bend under gentle pressure. Avoid using anything sharp like a needle or thumbtack, which can slip and scratch the phone.
What happens if I lose my SIM card?
Contact your carrier and request a replacement SIM card. They can usually mail one to you at no cost, or you can pick one up at a store. Once you have the new card, insert it into the slot the same way as the old one. Your carrier will set up it and your phone number will transfer to the new card.
Is it safe to open the SIM slot while the phone is on?
It's not dangerous, but powering off first is safer. Opening the slot while the phone is on can sometimes interrupt the connection briefly, which may cause a momentary error. Powering off avoids this entirely and takes only a few seconds.
My SIM tray is stuck and won't close. What should I do?
Make sure the SIM card is fully seated in the notch and not sticking out. If the card is in the right position and the tray still won't close, the tray itself may be bent. Do not force it closed. Visit an Apple Store or contact your carrier — they can inspect the tray and replace it if needed.
Do all iPhones have a SIM slot?
Most do, but some newer iPhone models sold in certain regions (like China) use eSIM only, which is a digital SIM built into the phone. Check your iPhone's specifications to confirm whether it has a physical SIM slot. If you're unsure, contact your carrier — they can tell you what type of SIM your phone uses.
