Transfer SIM or eSIM from iPhone to iPhone: Step-by-Step

Moving your phone number to a new iPhone is straightforward, whether you’re transferring a physical SIM card or an eSIM. This guide covers both methods, including how to use Quick Start, manual transfer, and carrier apps, so you can get your new device up and running quickly.

What You’ll Need

• Your old iPhone (with the SIM or eSIM you want to transfer)
• Your new iPhone (compatible with the same carrier)
• Both phones charged and connected to Wi-Fi (for eSIM transfer via Quick Start)
• Your carrier’s account information or app (for manual eSIM setup)
• A SIM ejector tool (if you’re moving a physical SIM)

Step-by-Step

Transferring a Physical SIM

1. Power off both iPhones. This prevents any SIM-related errors during the swap.
2. Locate the SIM tray. On most iPhones, it’s on the right side (or left on older models). Use the SIM ejector tool (or a paperclip) to gently push into the small hole next to the tray.
3. Remove the SIM tray and card. Pull the tray out and take the physical SIM card off it. Handle it by the edges to avoid touching the gold contacts.
4. Insert the SIM into the new iPhone. Place the SIM card into the tray of the new phone, matching the notch orientation, then push the tray back in until it clicks.
5. Power on the new iPhone. It should recognize the SIM automatically. If it doesn’t, check that the SIM is seated properly and restart the phone.

Transferring an eSIM (Using Quick Start)

1. Place both iPhones near each other. Ensure both are on, unlocked, and have Bluetooth and Wi-Fi enabled.
2. Start the Quick Start process. On your new iPhone, follow the initial setup until you see the “Quick Start� screen. Tap “Continue� and use your old iPhone to scan the animation on the new phone.
3. Complete the initial setup. Follow the on-screen instructions for Face ID, Touch ID, and Apple ID. When you reach the “Set Up Cellular� screen, you should see an option to “Transfer Your SIM� or “Transfer eSIM.�
4. Tap “Transfer eSIM.� This will initiate the transfer from your old iPhone to the new one. The old phone will show a confirmation prompt—tap “Confirm� on the old device.
5. Wait for the transfer to complete. The eSIM will be downloaded to your new iPhone. This may take a few minutes. Once done, your cellular plan will be active on the new device.

Transferring an eSIM (Manual Setup)

1. On your new iPhone, go to Settings > Cellular > Add Cellular Plan.
2. Choose how to add the plan. If you have a QR code from your carrier, select “Use QR Code� and scan it. Otherwise, choose “Enter Details Manually� and input the SM-DP+ address and activation code provided by your carrier.
3. Follow the prompts to activate. Your carrier may require you to confirm the transfer via text or phone call on your old device.
4. If you have a carrier app, use it. Many carriers have an app that lets you manage your eSIM. Log in and look for an option like “Transfer eSIM to New Phone� or “Add eSIM.�

Common Mistakes

• Not powering off before swapping a physical SIM. While it’s not always dangerous, it can cause the SIM to be read incorrectly or, in rare cases, corrupt data.
• Forgetting to remove the SIM from the old phone before selling or trading it. This leaves your number active on a device you no longer have.
• Assuming eSIM transfer is automatic. Quick Start doesn’t always offer the transfer, especially if your carrier doesn’t support it. You may need to contact them.
• Deactivating the eSIM on the old phone before the transfer completes. This can interrupt the process and cause errors.
• Ignoring carrier-specific requirements. Some carriers require you to contact them or use their app for eSIM transfers.

Tips

• Check carrier compatibility first. Not all carriers support eSIM transfers between iPhones. A quick call or website check can save you time.
• Keep your old iPhone until the transfer is confirmed. If something goes wrong, you still have a working phone.
• If using Quick Start, make sure both phones are on iOS 15 or later. The eSIM transfer feature is available on these versions.
• For physical SIMs, label the tray. If you’re moving multiple SIMs, a small sticker helps avoid mixing them up.
• After transferring, restart both phones. This helps clear any network glitches.

Troubleshooting

• New iPhone says “No SIM� or “Invalid SIM.� Remove the SIM, inspect it for damage, clean the gold contacts with a soft cloth, and reinsert it. If it still fails, try the SIM in another phone to rule out a damaged card.
• eSIM transfer fails during Quick Start. Restart both phones and try again. If it still fails, use the manual method (Settings > Cellular > Add Cellular Plan) or contact your carrier.
• eSIM is on the old phone but not on the new one. Go to Settings > Cellular on the new phone and tap “Add Cellular Plan.� If you see the plan listed, select it. If not, contact your carrier to re-send the activation details.
• You can’t receive texts to verify the transfer. Make sure the old phone has service. If it doesn’t, contact your carrier to authenticate you another way.
• After transferring, calls go to voicemail but data works. This often indicates a carrier-side issue. Toggle Airplane Mode on and off, then restart. If it persists, contact your carrier.

Frequently Asked Questions

Can I transfer a physical SIM to an iPhone with only an eSIM?

No, if the new iPhone doesn’t have a physical SIM tray (like some US models), you’ll need to convert your physical SIM to an eSIM. Contact your carrier to do this.

Does transferring an eSIM delete it from the old iPhone?

Yes, when you transfer an eSIM using Quick Start, it’s removed from the old phone automatically. If you use a manual method, you may need to remove it manually from the old phone’s settings.

How long does an eSIM transfer take?

Typically, it takes 2–5 minutes. It can be longer if your carrier needs to verify your identity manually.

Can I have the same number on two iPhones?

No, a phone number can only be active on one device at a time. Transferring the eSIM or SIM moves the number to the new phone.

What if my carrier doesn’t support eSIM transfer?

You can still move your physical SIM if you have one. If you’re using an eSIM, contact your carrier to get a new QR code or activation code for the new phone.

Do I need to contact my carrier before transferring?

Not usually for physical SIMs. For eSIMs, it depends on your carrier. Some allow self-service transfer, while others require you to call or use their app.
