Transfer AT&T eSIM to a Replacement iPhone

Switching to a new iPhone doesn’t mean you have to visit an AT&T store or wait for a physical SIM card. If your current iPhone uses an AT&T eSIM, you can transfer it to your replacement iPhone in a few minutes—either during the iPhone’s setup process or later from the Settings app. This guide walks you through both methods, what to do if something goes wrong, and common pitfalls to avoid.

What You’ll Need

• Your current iPhone with the active AT&T eSIM (it must be turned on and unlocked).
• Your replacement iPhone (must be compatible with eSIM—iPhone XS or newer, except iPhone SE 1st gen).
• Both iPhones connected to Wi-Fi or a cellular network.
• Your AT&T account PIN or passcode (in case you need to verify your identity).
• iOS 16 or later on both devices for the quick transfer method.

Step-by-Step

There are two main ways to transfer your eSIM: during the iPhone setup process or later via Settings. Choose the one that fits your situation.

Method 1: Transfer During iPhone Setup

1. Turn on your new iPhone and place it near your current iPhone (which should have the active AT&T eSIM).
2. Follow the on-screen prompts until you reach the “Quick Start” screen. Your current iPhone will show a message asking if you want to set up the new iPhone—tap Continue.
3. When you get to the “Set Up eSIM” screen, tap Transfer from Nearby iPhone.
4. Your current iPhone will display a confirmation. Tap Confirm on the old phone to authorize the transfer.
5. Wait for the new iPhone to activate the eSIM. This may take a minute or two. Once done, you’ll see “eSIM activated” or a checkmark.
6. Finish the rest of the setup (Face ID, Apple Pay, etc.). Your AT&T line will now be active on the new iPhone.

Method 2: Transfer Later via Settings

1. On your new iPhone, go to Settings > Cellular (or Mobile Data).
2. Tap Add Cellular Plan.
3. Choose Transfer from Nearby iPhone. Your new iPhone will scan for nearby devices.
4. On your old iPhone, a pop-up will appear asking if you want to transfer your plan. Tap Transfer.
5. Enter your AT&T account PIN if prompted (this is the same PIN you use for your AT&T account).
6. Wait for the activation to complete. You may see a message like “Your eSIM is ready.”
7. If you have multiple lines, label the new one (e.g., “Personal”) so you can identify it later.

If neither method works, you can also use the AT&T app or website to download a new eSIM to your replacement iPhone. Log in to your AT&T account, go to My Device > SIM, and follow the steps to get a new eSIM QR code. Then on the new iPhone, go to Settings > Cellular > Add Cellular Plan and scan the QR code.

Common Mistakes

• Turning off the old iPhone too soon. The transfer requires the old phone to be on and nearby until the eSIM is activated on the new one.
• Not checking compatibility. Both iPhones must support eSIM. The old iPhone must be running iOS 16 or later for the quick transfer; otherwise, you’ll need to scan a QR code.
• Forgetting your AT&T PIN. Some transfers require the account PIN. If you don’t have it, you’ll be stuck until you reset it.
• Removing the eSIM from the old phone before the new one is active. This can cause a temporary loss of service if the transfer fails.
• Assuming the transfer is instant. It can take up to 10 minutes. Don’t panic if it doesn’t appear immediately.

Tips

• Keep both iPhones plugged into power during the transfer to avoid a dead battery mid-process.
• If you’re trading in your old iPhone, make sure to erase it after the eSIM transfer is confirmed, not before.
• If you have multiple AT&T lines (e.g., personal and business), repeat the transfer for each line.
• Write down your IMEI and eSIM ICCID (found in Settings > General > About) before you start—this helps if you need to contact AT&T support.
• If you’re traveling internationally, you can still transfer the eSIM, but the new iPhone must be unlocked or compatible with AT&T’s network.

Troubleshooting

If the transfer doesn’t go smoothly, try these steps in order:

1. Restart both iPhones. A simple reboot can clear temporary glitches.
2. Make sure both are on the latest iOS. Go to Settings > General > Software Update on both devices.
3. Turn off Wi-Fi on the old iPhone. Sometimes the transfer works better over cellular.
4. Try the QR code method. Log into your AT&T account and generate a new eSIM QR code. On the new iPhone, go to Settings > Cellular > Add Cellular Plan and scan it.
5. Contact AT&T support. They can push the eSIM to your new iPhone remotely. Have your account number and PIN ready.
6. If you see “No SIM” or “Invalid SIM” on the new iPhone, remove the eSIM (Settings > Cellular > Remove Cellular Plan) and add it again using the QR code method.

Frequently Asked Questions

Q: Can I transfer my AT&T eSIM without the old iPhone?
A: Yes, but you’ll need to contact AT&T or use your online account to get a new QR code. You can’t use the “Transfer from Nearby iPhone” feature without the old device.

Q: Will I be charged for transferring my eSIM?
A: AT&T typically doesn’t charge for eSIM transfers, but it’s always a good idea to check your account for any fees.

Q: How long does the transfer take?
A: Usually 1-5 minutes, but it can take up to 10 minutes in some cases. If it takes longer, restart the process.

Q: Can I transfer my eSIM to an iPhone that is still locked to another carrier?
A: No, the replacement iPhone must be unlocked or locked to AT&T. If it’s locked to another carrier, you’ll need to unlock it first.

Q: What happens to my old iPhone’s eSIM after transfer?
A: It should be automatically deactivated. If not, you can manually remove it in Settings > Cellular > Remove Cellular Plan.

Q: I have an eSIM and a physical SIM on my old iPhone. Can I transfer both?
A: Yes, you can transfer the eSIM as described. The physical SIM can be moved to the new iPhone if it has a SIM slot, or you can convert it to an eSIM via AT&T.
