How to Replace or Switch an iPhone SIM/eSIM (7-16)

How to Replace or Switch the SIM Card on iPhone (iPhone 7 to iPhone 16)

To replace the SIM card on an iPhone, you generally need to eject the side tray using a removal tool, though newer models often use digital eSIMs instead. Whether you are upgrading your device, switching carriers, or traveling internationally in 2026, the process depends on your specific model. This guide covers everything from the physical trays found on the iPhone 7 through iPhone 13, to the eSIM-only configuration of US-based iPhone 14, 15, and 16 models.

Summary

Changing your SIM card allows you to switch phone numbers or carriers while keeping your device. This guide walks you through locating the SIM slot, using the ejector tool safely, and managing the digital transition for newer iPhones that lack physical trays. You will learn the specific differences between older models and the latest iPhone 16 lineup to ensure a smooth swap.

TLDR

• Identify if your iPhone uses a physical Nano-SIM or a digital eSIM before starting.
• Use a SIM ejector tool or a small bent paperclip to pop open the tray on compatible models.
• US models of the iPhone 14, 15, and 16 do not have physical SIM trays; you must use settings to transfer service.
• The SIM tray is located on the right side for iPhone 7-11 and on the left for iPhone 12-16 (international models).
• Make sure to align the notched corner of the SIM card correctly when placing it in the tray.
• Restarting your phone after the swap helps the device recognize the new network signal.

Does My iPhone Have a Physical SIM Card Slot?

Determining if your device has a slot is the first step, especially with the changes made in recent years. If you are holding an iPhone 13 or older (including the iPhone SE lines), your phone definitely has a physical SIM card slot.

However, confusion often arises with newer generations. If you bought an iPhone 14, 15, or 16 in the USA, your device is eSIM-only and does not have a physical tray. Apple removed the physical hardware to save space and improve water resistance in the US market. If you are looking for the "iphone 16 sim card slot" on a US model, you will not find one.

Conversely, if you purchased your iPhone 14, 15, or 16 in Europe, Asia, or other international markets, it likely still retains the physical slot. Therefore, "do iphone 13 have sim cards" is a definite yes, while questions like "iphone 14 pro sim free" depend entirely on where the device was manufactured.

How to Remove the SIM Card from iPhone (Physical Tray)

If you have confirmed your device has a tray, learning how to remove the SIM card from your iPhone is a straightforward mechanical process. This method applies universally to all Apple phones with trays, whether you need to replace the SIM card on an iPhone 7 or an iPhone 11.

Locating the SIM Tray on Your Model

The location of the tray shifts slightly depending on the generation of your phone. You are looking for a small oval cutout on the metal band of the phone with a tiny pinhole next to it.
• iPhone 12 through iPhone 16 (International): The tray is located on the left side of the device, below the volume buttons.
• iPhone 4 through iPhone 11 (and iPhone SE 2/3): The tray is located on the right side of the device, usually midway down or near the power button.

Ejecting the Tray and Swapping the Card

To perform an iPhone SIM card removal, follow these steps carefully:
1. Insert the SIM ejector tool (or a paperclip) into the small pinhole on the tray.
2. Push firmly toward the device—not sideways—until the tray pops out.
3. Gently pull the tray completely out of the phone.
4. Remove the old card and place your new Nano-SIM into the tray.
5. Notice the "notch" or cut corner on the SIM card; it will only fit into the tray in one specific orientation.
6. Slide the tray back into the phone until it clicks shut.

Once the hardware is physically installed, you may need to activate your new SIM card through your carrier if it is a fresh plan. If you are searching for "how to open sim card slot" or "how to get sim card out of iphone," these steps are the universal standard for all physical trays.

How to Open the SIM Slot Without a Tool

If you have lost the official Apple tool, you can still learn how to open the SIM card slot without a tool using common household items. The safest alternative is a sturdy paperclip. Bend one end of the paperclip straight and use it just like the original tool.

Other options include a safety pin (use the blunt end if possible) or a stiff earring post. However, be very careful. Do not use sewing needles or extremely sharp, brittle objects. These can snap off inside the hole or damage the internal mechanism, making it impossible to get the SIM card out later.

Replacing or Transferring an eSIM (iPhone 14, 15, 16)

To replace the SIM card on an iPhone 14, 15, or 16 purchased in the US, you must perform a digital transfer because there is no physical card to touch. This is known as an eSIM (embedded SIM).

Instead of using a tool, you will navigate to Settings > Cellular > Add eSIM. Your carrier will typically provide a QR code to scan, or they may push the plan directly to your phone notification center. If you are switching from an older iPhone to an iPhone 16, Apple offers a "Transfer from nearby iPhone" feature during the setup process that moves your number wirelessly. This answers the need to "replace sim card on iphone 15" or newer models without hunting for a paperclip.

Troubleshooting SIM Card Issues

After you replace the card, you might encounter minor issues. If you see a "No SIM" or "Invalid SIM" error, try restarting your iPhone first; this forces the modem to re-read the card. If that fails, eject the tray again and ensure the card is seated perfectly flat. If the tray itself feels stuck and won't open, do not force it. It is better to take the device to an Apple Store than to break the internal pins.

FAQ

Can I put my SIM card in another phone?

Yes, you can put your SIM card in another phone as long as the new device is unlocked or locked to the same carrier. Since the iPhone 5, Apple has used the Nano-SIM standard, so the physical size of the card is compatible all the way up to the international iPhone 16.

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

No, you do not need to turn off your iPhone. iPhones support "hot-swapping," which means you can change the SIM while the phone is powered on. The phone will briefly lose signal and then search for the new network. However, a restart is often recommended if the new signal doesn't appear immediately.

Where is the SIM card on iPhone 7 specifically?

The SIM card on the iPhone 7 is located on the right side of the device. It is positioned roughly halfway down the side rail, below the power button.

Will I lose my data if I change my SIM card?

No, you will not lose your personal data. Your photos, apps, messages, and contacts are stored on the iPhone's internal memory or in iCloud. The SIM card only holds your phone number and carrier account information.
