What happens to your eSIM when you get a new iPhone

Your eSIM is a digital copy of your phone plan stored on your phone's chip, not on a physical card. When you switch to a new iPhone, your eSIM does not automatically move over — you have to transfer it yourself. The process differs depending on whether you're switching within the Apple ecosystem (from one iPhone to another) or coming from a different phone brand.

The good news: if you're moving between iPhones, Apple's setup process can transfer your eSIM during the initial setup. If you're coming from an Android phone or if that automatic transfer doesn't work, your carrier can send you a new eSIM set up code, or you can read the carrier's app and request a transfer from there.

Before you start, back up your old phone and have your carrier's customer service number handy. You'll also need the phone number or account number associated with your plan.

Key Takeaways

  • When you set up a new iPhone next to your old one, the setup process can transfer your eSIM automatically if both phones are on the same carrier.
  • If automatic transfer doesn't work, contact your carrier and ask them to send you an eSIM set up code via email or SMS.
  • You can also read your carrier's app on the new iPhone and request the eSIM transfer from within the app.
  • Your old phone will lose service once the eSIM is transferred, so complete the move when you're ready to switch phones entirely.

Transferring your eSIM during iPhone setup

If you're upgrading from an older iPhone to a new one and both phones are on the same carrier, the easiest route is to let Apple handle the transfer during setup. Turn on your new iPhone and place it next to your old one. When the setup screen appears, tap "Transfer from iPhone" and follow the on-screen prompts.

During setup, you'll see an option to transfer your eSIM. Tap "Transfer eSIM" when prompted. Your old phone will ask you to confirm the transfer. Once you confirm, the eSIM moves to the new phone and your old phone loses service. This process usually takes a few minutes.

This method works best when both phones are on the same carrier and your account is in good standing. If the transfer option doesn't appear during setup, your carrier may require you to request the transfer manually instead.

Requesting an eSIM transfer code from your carrier

If the automatic transfer didn't work, or if you're switching from a non-iPhone phone, contact your carrier directly. Call their customer service line or visit their website and look for "eSIM transfer" or "eSIM setup" in the support section. Have your account number or the phone number on your plan ready.

Tell the representative you want to transfer your eSIM to a new iPhone. They will send you an set up code via email or text message. This code is usually a QR code or a long alphanumeric string. Save this code somewhere safe — you'll need it to set up your eSIM on the new phone.

The carrier will also tell you when the transfer takes effect. Some carriers deactivate the old phone when ready; others give you a window of time. Ask before you hang up so you know when to expect the switch.

Setting up the eSIM on your new iPhone using a code

Once you have your set up code, open Settings on your new iPhone and go to Cellular. Tap "Add eSIM" or "Add Cellular Plan." You'll see options to scan a QR code or enter details manually. If your carrier sent a QR code, use your camera to scan it. If they sent a text code, tap "Enter Details Manually" and type it in.

Your iPhone will contact your carrier and read your plan. This usually takes less than a minute. Once it's done, you'll see your carrier name and phone number in the Cellular settings. Your service should be active when ready.

If you see an error message, check that you typed the code correctly. If the problem persists, contact your carrier — they may need to resend the code or troubleshoot on their end.

Using your carrier's app to transfer your eSIM

Many carriers offer their own apps that let you request an eSIM transfer without calling. read your carrier's app on the new iPhone and sign in with your account credentials. Look for a menu option like "Manage eSIM," "Transfer eSIM," or "Add a Line."

Follow the app's prompts to request the transfer. Some apps will generate a QR code you can scan directly into Settings > Cellular. Others will send you an set up code via email. The process varies by carrier, but the end result is the same: your eSIM gets set up on the new phone.

This method is often faster than calling, especially if your carrier's app is well-designed. However, not all carriers offer this option, so check whether your carrier has an app before you try this route.

What to do if your eSIM transfer fails

If your new iPhone doesn't recognize the set up code, or if you get an error during setup, first check that you're on Wi-Fi or have cellular service on another device nearby. eSIM setup requires an internet connection to contact your carrier's servers.

If you're connected to the internet and still seeing an error, restart your new iPhone and try again. If that doesn't work, contact your carrier. Tell them the exact error message you saw. They may need to resend the code, check your account status, or confirm that your old phone has been deactivated.

In rare cases, your carrier may need to issue a new eSIM entirely if the original code expires or becomes corrupted. This is free and usually takes a few minutes to process.

Switching carriers when you move to a new iPhone

If you're moving to a new iPhone and also switching to a different carrier, you cannot transfer your old eSIM. Instead, contact your new carrier and ask them to set up a new eSIM for you. They will provide an set up code or QR code. Follow the same steps as above to add it to your new iPhone.

Before you switch, make sure your old carrier has deactivated your service. This prevents accidental charges and ensures your old phone number is released. Some carriers require you to call to request deactivation; others do it automatically when they detect the eSIM has been removed.

If you're keeping your phone number, ask your new carrier about porting. They will handle the transfer of your number from your old carrier to the new one. This usually takes a few hours to a full business day.

Frequently Asked Questions

Can I have the same eSIM on two iPhones at the same time?

No. An eSIM can only be active on one phone at a time. Once you transfer it to your new iPhone, it stops working on your old phone. If you need service on both phones, you'll need two separate eSIMs from your carrier, which usually means two separate plans.

What if I don't have my old iPhone anymore?

You can still transfer your eSIM. Contact your carrier and tell them you want to move your eSIM to a new phone but no longer have the old one. They will send you an set up code without requiring confirmation from the old phone. The process is the same from there.

Do I lose my phone number when I transfer my eSIM?

No. Your phone number stays the same when you transfer your eSIM. The eSIM is just the digital version of your plan, so moving it to a new phone doesn't change your number or your account.

How long does an eSIM set up code stay valid?

Most carriers keep set up codes valid for 30 days, though this varies. If your code expires, contact your carrier and ask them to send a new one. It's free and takes just a few minutes.

Can I transfer my eSIM if I owe money on my account?

Most carriers will transfer your eSIM even if you have an outstanding balance, as long as your account is not suspended. If your account is suspended, contact your carrier to resolve the issue first. Once your account is active again, you can request the eSIM transfer.
