New iPhones use eSIM instead of physical SIM cards in most markets

Starting with the iPhone 14 in 2022, Apple removed the physical SIM card slot from iPhones sold in the United States. Instead, new iPhones use eSIM — a digital SIM that lives in your phone's software rather than a physical chip. If you buy an iPhone 14, 15, or 16 in the US, you will not find a SIM tray at all.

Outside the US, the situation is different. iPhones sold in most other countries still have a physical SIM slot alongside eSIM capability, giving you the choice of which to use. This matters if you travel internationally or buy your phone outside the US and bring it home.

The shift to eSIM-only in the US happened because carriers like Verizon, AT&T, and T-Mobile all supported it by 2022, and Apple wanted to simplify the hardware. You still need a SIM to connect to a carrier — it just lives in your phone's settings instead of in a physical slot.

Key Takeaways

  • iPhones sold in the United States since the iPhone 14 have no physical SIM slot and use only eSIM.
  • iPhones sold outside the US typically have both a physical SIM slot and eSIM capability, letting you choose which one to use.
  • eSIM is activated through your carrier's app or website, not by inserting a physical card.
  • If you switch carriers or travel internationally, you can add a second eSIM to your phone without removing anything.

How eSIM works on newer iPhones

An eSIM is a digital profile that your carrier sends to your phone over the internet. When you set up a new iPhone or switch carriers, you do not insert anything — instead, you scan a QR code, enter a code manually, or use your carrier's app to download the eSIM profile directly to your phone.

Your iPhone stores this profile in a chip inside the phone called the embedded SIM. The phone can hold multiple eSIM profiles at once, though you can only use one carrier at a time. This means you can store an eSIM for your home carrier and a separate eSIM for international travel, then switch between them in Settings without physically changing anything.

The activation process varies by carrier. Verizon, AT&T, and T-Mobile all let you set up eSIM through their apps or websites. Some carriers send you a QR code by email or text; others let you request the eSIM directly in their app. The whole process usually takes a few minutes once you have your account number and PIN.

Which iPhones still have physical SIM slots

If you own an iPhone 13 or earlier, your phone has a physical SIM slot. The iPhone 13, 12, 11, and all older models use a nano-SIM card — a small rectangular chip that slides into a tray on the side of the phone. These phones also support eSIM, so you can use either a physical SIM or a digital one, or both at the same time.

The iPhone SE (third generation, released in 2022) also has a physical SIM slot, even though it came out around the same time as the iPhone 14. Apple kept the SIM slot in the SE because it is positioned as a budget option and some users still prefer physical SIM cards.

If you bought your iPhone outside the United States — even a newer model like the iPhone 15 or 16 — it almost certainly has a physical SIM slot. Apple sells different hardware versions by region. A phone purchased in Europe, Asia, or most other countries will have both a SIM slot and eSIM support.

What to do if you have a US iPhone 14 or newer

When you first set up your new iPhone, you will be asked to activate a carrier. You can do this during setup by scanning a QR code or entering an activation code, or you can skip it and set up eSIM later through Settings. Either way, you need to contact your carrier to get the activation information.

If you are switching from an older iPhone, your carrier can transfer your existing SIM to eSIM. Call your carrier's customer service or visit a store and ask them to convert your SIM to eSIM. They will send you a QR code or activation code, which you scan in Settings on your new phone. The process is free.

If you are keeping your old phone as a backup or selling it, remember that the eSIM is tied to your new phone, not your old one. Your old phone will lose service once you move the eSIM. If your old phone has a physical SIM, you can remove that card and use it in another device if needed.

Traveling internationally with a US iPhone

One advantage of eSIM is that you can add a local carrier's eSIM while traveling without removing anything from your phone. Many countries have carriers that offer eSIM profiles for tourists — you can buy one through their app or website and activate it on your phone within minutes.

Your iPhone can store multiple eSIM profiles. You might have your home carrier (Verizon, AT&T, or T-Mobile) as your primary eSIM and add a second eSIM from a local carrier when you travel. In Settings, you can switch which eSIM is active, or set up dual SIM mode to use both at once.

If you travel frequently and prefer a physical SIM card, you have two options: buy an iPhone with a physical SIM slot (which means purchasing outside the US), or stick with an iPhone 13 or earlier. Otherwise, eSIM is your only choice on newer US iPhones.

Troubleshooting eSIM problems on new iPhones

If your eSIM is not activating, first check that you are connected to Wi-Fi or cellular data — eSIM activation requires an internet connection. If you are already online, restart your phone and try again. If the problem persists, contact your carrier; they can resend the activation code or QR code.

If you see an error message saying "Unable to add eSIM" or "Invalid QR code," make sure you are using the correct code for your phone. Some carriers send different codes for different devices. Double-check the email or text from your carrier and try scanning again, or enter the code manually if the QR code is not working.

If you switched phones and your eSIM did not transfer, your old phone may still be using it. Call your carrier and ask them to deactivate the eSIM on your old phone, then reactivate it on your new one. This usually takes a few minutes and is free.

Frequently Asked Questions

Can I use a physical SIM card in an iPhone 14 or newer?

No, US iPhones from the iPhone 14 onward have no physical SIM slot. If you need a physical SIM, you must use an iPhone 13 or earlier, or buy an iPhone outside the US. All newer US iPhones use eSIM only.

What happens to my eSIM if I get a new phone?

Your eSIM is tied to your old phone until you contact your carrier and ask them to move it. Call your carrier, give them your new phone's details, and they will deactivate the eSIM on your old phone and send you an activation code for your new one. The old phone will lose service once the eSIM is moved.

Can I have two phone numbers on one iPhone?

Yes, if your iPhone supports dual SIM. Newer iPhones can store multiple eSIM profiles and use two at the same time — one for calls and texts, one for data, or both active simultaneously. You manage this in Settings under Cellular. Your carrier determines whether this feature is available on your plan.

Do I need to buy a new SIM card when I upgrade to a new iPhone?

No. If you are upgrading to an eSIM-only iPhone, your carrier will convert your existing SIM to eSIM at no cost. If you are upgrading to an older iPhone with a physical slot, you can reuse your old SIM card if it is still in good condition, or your carrier can send you a new one.

Is eSIM more secure than a physical SIM?

eSIM and physical SIM cards have different security considerations. eSIM cannot be physically stolen or swapped, but it can be compromised if someone gains access to your carrier account. Physical SIM cards can be removed and used elsewhere. Both require your carrier's authentication to activate, so security depends more on protecting your account password than on the SIM type itself.
