You’re staring at that tiny, stubborn hole on the side of your expensive titanium or aluminum frame. Maybe you just bought a shiny new iPhone 15 or 16 and realized your old physical SIM won't fit because you're in the US and it's all eSIM now. Or maybe you're traveling, and you need to swap in a local carrier's plastic card to avoid those soul-crushing roaming charges. Whatever the reason, figuring out how to open the iPhone SIM card tray feels like performing microsurgery on a device that costs a month's rent.
It’s nerve-wracking.
Most people worry they’re going to poke the wrong hole. You see two little dots—one is the SIM tray, and the other is a microphone. Stick a pin in the wrong one, and you’re looking at a very expensive repair bill for a punctured waterproof mesh.
Where is the tray actually located?
Apple isn't exactly consistent. Over the years, they’ve moved the SIM slot around like a game of musical chairs. If you have an iPhone 12 or newer, look on the left side. It’s usually sitting right below the volume buttons. If your phone is an older model—say, an iPhone 11, an XR, or even that trusty old iPhone 6—you’ll find it on the right side, just under the power button.
Then there’s the big "oops" for American buyers. If you bought an iPhone 14, 15, or 16 in the United States, stop looking. There isn't a tray. Apple ditched physical SIMs entirely for the US market, moving fully to eSIM. If you see a seam on the side of a US-model iPhone 15, that’s actually the mmWave 5G antenna window, not a SIM slot. Don't try to pry it open. You'll regret it.
Finding the right tool for the job
Ideally, you still have that little silver "poker" that came in the original iPhone box. It’s technically called the SIM eject tool. It’s flimsy, easy to lose, and probably sitting at the bottom of a junk drawer under three dead AA batteries.

If you can't find it, don't panic. A standard paperclip is the universal gold standard for this. Just bend the outer leg out. Avoid using needles or safety pins if you can help it. They’re too sharp and can slip, scratching the finish of your phone or, worse, sliding past the internal lever and getting stuck. A thumbtack is okay in a pinch, but the grip is awkward.
How to open the iPhone SIM card tray like a pro
Here is the secret: you have to push harder than you think, but with total control.
First, power down the phone. Technically, you can hot-swap a SIM card while the phone is on, but it’s a bad habit. It can occasionally confuse the software, leading to "No Service" errors that require a full network reset anyway. Just turn it off.
Insert your tool into the small circular opening on the tray. Keep the tool perpendicular to the phone. If you angle it, you’re just gonna scrape the side. Apply firm, steady pressure. You’ll feel a slight "pop." That’s the internal spring-loaded lever releasing the catch. The tray will jump out about two millimeters.
Once it's popped, use your fingernails to pull it the rest of the way.
Dealing with a stuck tray
Sometimes the tray won't budge. This usually happens because of "pocket lint glue." Over a year or two, tiny fibers and skin oils migrate into the seam, creating a seal that's surprisingly strong.
If it’s stuck, do not—under any circumstances—use a screwdriver to pry it. You will bend the metal frame. Instead, try a quick blast of compressed air into the hole to clear out debris. If that fails, a tiny drop of high-percentage isopropyl alcohol on the end of your paperclip can sometimes dissolve the grime holding the gasket in place.
Apple uses a rubber O-ring around the tray to keep the iPhone water-resistant (standard IP68 rating). If that rubber has degraded or gotten sticky, it might require a bit more "oomph" to break the seal.

Navigating the eSIM transition
We have to talk about the elephant in the room. Physical SIM cards are dying.
Apple’s push toward eSIM is annoying for people who like to swap phones frequently, but it’s actually more secure. If someone steals your phone, they can’t just pop out the SIM to stop you from tracking it via Find My. With an eSIM, the "card" is embedded in the motherboard.
If you’re trying to open the tray because you’re switching carriers, check your settings first. Go to Settings > General > About and scroll down to "Carrier Lock." If it says "SIM Locked," it doesn't matter how many times you open that tray; a new card won't work. You’ll need to contact your original provider to unlock the IMEI.
Putting it all back together
When you’re ready to close things up, look at the tray. It only goes in one way. There’s a tiny notch in one corner of the SIM card that matches the tray's shape. It’s like a puzzle piece.
- Lay the card flat in the tray.
- Ensure it's flush. If the card is sticking up even a fraction of a millimeter, it will snag when you slide it in.
- Align the hole on the tray with the internal pin.
- Slide it back in until you hear or feel a click.
If you feel significant resistance, stop. Pull it out and check the alignment. Forcing a misaligned tray is the fastest way to break the internal pins on the logic board, which is an "out-of-warranty" replacement of the entire guts of the phone.

Troubleshooting the "No SIM" error
You've put it back in, you've turned the phone on, and... nothing. "No SIM Card Installed."
Don't assume the tray is broken. Usually, it’s just a smudge. Skin oils are surprisingly non-conductive. Take the tray back out and wipe the gold contacts of the SIM card with a microfiber cloth or a clean t-shirt. Avoid touching the gold part with your bare fingers.
If it still doesn't work, try the card in another phone. SIM cards actually have a lifespan. They can "burn out" or get corrupted. Most carriers will give you a replacement SIM for free if you walk into a retail store and show them the old one isn't registering.
Why the hole is actually a lever
It’s interesting how this works internally. When you push the pin into the hole, you aren't actually pushing the tray. You're pushing a small metal lever. This lever pivots and pushes the tray out from the inside. This design is why you need a blunt tool like a paperclip rather than a sharp needle. A sharp point can actually slide off the lever's surface and jam into the internal chassis.
If you’ve accidentally poked the microphone hole (the one without the tray outline around it), don’t panic yet. Most modern iPhones have a protective L-shaped channel for the microphone. This means the pin usually hits a wall before it hits the delicate waterproof membrane. If your mic still sounds clear in Voice Memos, you got lucky.
Actionable steps for a smooth swap
Before you go poking around at your $1,000 smartphone, keep these final tips in mind to ensure you don't end up at the Genius Bar.
- Work over a flat, light-colored surface. SIM cards are tiny. If you drop a Nano-SIM on a dark shag carpet, it’s gone forever.
- Check for the "notch." Always match the diagonal cut on the corner of the card to the tray.
- Keep your old SIM. Even if you're switching to eSIM, keep the physical card for a few days. Sometimes you need to receive a final "porting" text message on the old line to authorize the transfer.
- Verify your model. If you have a Chinese or Hong Kong model iPhone, your tray might be "double-sided." These models support two physical SIM cards back-to-back rather than one SIM and one eSIM.
If the tray is physically damaged or bent, don't try to straighten it with pliers. A replacement tray costs about $5 online. Using a bent tray can permanently damage the internal slot, making it impossible to ever get a card in or out again. Just buy a new tray that matches your phone's color and save yourself the headache.
Once the card is seated and the tray is flush with the frame, your iPhone should automatically pick up the network signal within 30 seconds. If it doesn't, toggle Airplane Mode on and off to force a fresh handshake with the cell tower.
