The short answer: newer iPhones still use SIM cards, but Apple removed the physical slot

Starting with the iPhone 14 in the United States, Apple stopped including a physical SIM card slot. Instead, these phones use eSIM (embedded SIM), which is a digital version of the same thing. Your phone still connects to a carrier — it just does so through software instead of a tiny plastic card you insert into a tray.

If you have an iPhone 15, iPhone 14, or any newer model sold in the US, you will set up your carrier connection through your phone's settings menu rather than by sliding a SIM card into the side of the device. Older iPhones — the 13 and earlier — still have the physical slot and still use physical SIM cards, though they can also use eSIM at the same time.

The change matters because it affects how you switch carriers, what happens if your phone breaks, and whether you can use a second phone number on the same device. It does not mean you no longer need a carrier or that your service works differently once it is set up.

Key Takeaways

  • iPhone 14 and newer models in the US have no physical SIM slot and use eSIM instead, which stores your carrier information digitally on the phone itself.
  • Older iPhones (13 and earlier) still have a physical SIM slot and can use either a physical SIM card or eSIM, or both at the same time.
  • Switching carriers with an eSIM is faster than with a physical card because you can do it through settings without visiting a store or waiting for mail.
  • If your iPhone with eSIM breaks or is lost, your carrier can transfer your number to a new phone through their website or app rather than mailing you a replacement card.

What eSIM actually is and how it works

A SIM card — whether physical or embedded — is a small piece of data that tells your phone which carrier you use and which phone number belongs to you. A physical SIM is a card you can hold. An eSIM is the same information, but it lives inside your phone's hardware instead of on a removable card.

When you set up eSIM on an iPhone 14 or newer, you scan a QR code your carrier gives you, or you enter a code manually. The phone downloads your carrier information and stores it. From that moment on, your phone knows it belongs to that carrier. You do not need to insert anything, and you cannot lose the card because there is no card to lose.

The carrier information is tied to that specific phone. If you get a new iPhone, you will need to set up eSIM again on the new device — your carrier can help you do this through their website or app, and it usually takes a few minutes.

How switching carriers works with eSIM versus a physical SIM

With a physical SIM card, switching carriers means getting a new card in the mail or visiting a store, then inserting it into your phone. With eSIM, you can switch entirely through your phone's settings or your new carrier's app, often in under an hour.

Most carriers now let you request an eSIM transfer online. You log into your new carrier's website, request the transfer, scan a QR code, and your phone downloads the new carrier information. Your old carrier's information is replaced. You do not need to visit a store, wait for mail, or touch any hardware.

Some carriers still require you to call or visit in person to switch, but this is becoming less common. If you are thinking about switching carriers, it is worth checking whether your new carrier supports eSIM transfer online — it is one of the real advantages of the change.

What happens if your phone breaks or is lost

If your iPhone with eSIM is damaged, stolen, or lost, your carrier can move your phone number to a new phone without mailing you anything. You contact your carrier, they verify your identity, and they send the eSIM information to your new phone digitally. This usually takes a few minutes to a few hours.

With a physical SIM, the same process requires waiting for a replacement card to arrive by mail, which can take several days. If you travel frequently or cannot afford downtime, eSIM is faster.

One trade-off: if your phone is broken but still powered on, a thief could potentially use it before you report it lost. With a physical SIM, you could remove the card and the phone would be useless to them. With eSIM, you have to contact your carrier to disable the number. Most carriers can do this quickly, but it is one reason to report a lost phone when ready.

Using two phone numbers on one iPhone

iPhones with eSIM can hold two carrier profiles at the same time — one on eSIM and one on a physical SIM (if the phone has a slot), or two eSIMs (on iPhone 13 and newer). This means you can have a work number and a personal number on the same phone, or a US number and an international number.

You can switch between them in settings, and calls and texts will route to whichever one you have active. This is useful if you travel internationally and want to use a local carrier without losing your home number, or if your employer requires a separate work line.

Older iPhones with a physical SIM slot can do this too — one physical SIM plus one eSIM. The difference is that newer iPhones can do it with two eSIMs, so you do not need to carry or swap physical cards.

Which iPhones have eSIM and which still have a physical slot

In the United States, iPhone 14, iPhone 14 Plus, iPhone 14 Pro, iPhone 14 Pro Max, iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max have no physical SIM slot — only eSIM. All earlier models (iPhone 13 and older) have a physical SIM slot.

Outside the US, the situation is different. Some countries still require physical SIM cards for regulatory reasons, so iPhones sold in those regions may still have a physical slot even if they are the same model number. If you are buying an iPhone internationally or traveling with one, check your carrier's website to see what they support in that country.

If you already own an iPhone 13 or older, you do not need to change anything. Your phone works exactly as it always has. You can keep using a physical SIM, or you can ask your carrier to set up eSIM on the same phone if you want to try it.

Why Apple made this change

Apple removed the physical SIM slot to make iPhones thinner and to simplify the design. A SIM tray takes up physical space inside the phone, and removing it allowed Apple to fit slightly more battery or other components into the same size device.

From Apple's perspective, eSIM is also more find — the information is encrypted on the phone itself rather than on a removable card that could be stolen or swapped. And it is faster for carriers to set up service, since they do not have to manufacture and mail physical cards.

The downside is that you cannot physically swap a SIM card between phones anymore. If you have an older phone you want to use temporarily, you cannot just move the card over — you have to contact your carrier and have them set up eSIM on the other phone. This is a real inconvenience for some people, which is why older iPhones with physical slots are still worth buying if you prefer that flexibility.

Frequently Asked Questions

Can I still use a physical SIM card with a new iPhone?

No. iPhone 14 and newer models sold in the US have no physical SIM slot at all. If you need a physical SIM card, you would need to use an iPhone 13 or older. Some countries outside the US still sell newer iPhones with a physical slot, but US models do not.

What if my carrier does not support eSIM yet?

Most major carriers in the US now support eSIM, including Verizon, AT&T, T-Mobile, and many smaller carriers. If your carrier does not, you have two options: ask them when they plan to support it, or consider switching to a carrier that does. You can check your carrier's website to see if they offer eSIM.

If I buy an iPhone 14 or 15, can I use it with my old physical SIM card?

No. These phones have no slot for a physical SIM. You will need to contact your carrier and ask them to set up eSIM instead. This is a free process and usually takes a few minutes.

Do I need to pay extra for eSIM?

No. eSIM is the same service as a physical SIM — it costs nothing extra and does not change your monthly bill. Your carrier may charge you to replace a lost SIM (physical or digital), but setting up eSIM for the first time is free.

Can I travel internationally with eSIM?

Yes. When you travel, you can ask your home carrier to set up a second eSIM profile on your phone with a local carrier's information, or you can temporarily switch your main eSIM to a local carrier. You keep your home number on the second profile and can switch between them in settings. This is one of the main advantages of eSIM for frequent travelers.
