What happens to your eSIM when you get a new iPhone

Your eSIM is a digital copy of your phone plan stored on your current phone's chip. When you switch to a new iPhone, the eSIM does not automatically move over — you have to transfer it yourself or ask your carrier to send you a new one. The method depends on whether your old phone still works, whether your carrier supports eSIM transfers directly, and which iPhone models you own.

The fastest route is usually to transfer the eSIM during iPhone setup using your old phone and new phone together. If your old phone is broken or unavailable, your carrier can deactivate the eSIM on the old device and send you a new one for the new phone. Both paths take a few minutes to an hour, depending on your carrier.

Key Takeaways

  • If your old iPhone still works, use the transfer option during setup on your new phone — this is the fastest method and works with most carriers.
  • You need both phones present and powered on to transfer an eSIM during setup, and the transfer happens over Wi-Fi or cellular.
  • If your old phone is broken or unavailable, contact your carrier directly and ask them to deactivate the eSIM and issue a new one for your new device.
  • Some carriers let you manage eSIMs through their app or website; check your carrier's support page to see what options they offer.
  • After transfer, your old phone will lose cellular service on that plan, though it can still use Wi-Fi calling if you set it up beforehand.

Transfer your eSIM during iPhone setup (both phones working)

This is the standard path when your old iPhone is still powered on and functional. Start the setup process on your new iPhone and keep your old iPhone nearby.

When the new iPhone reaches the "Transfer Your SIM" screen during setup, tap Transfer eSIM. The new phone will show a code on screen. On your old iPhone, go to Settings > Cellular > Cellular Plans (or Mobile Data on older iOS versions), find your plan, and tap the three dots or menu icon next to it. Select Transfer to Another iPhone or Transfer eSIM, then scan the code shown on the new phone using the old phone's camera. The transfer usually completes in one to two minutes.

After the transfer finishes, your old phone will show no cellular service on that plan. Your new iPhone will have full service. If you plan to keep using the old phone on Wi-Fi, make sure you set up Wi-Fi calling before you transfer — you cannot add it after the eSIM leaves.

Request a new eSIM from your carrier (old phone unavailable)

If your old iPhone is lost, broken, or you do not have it with you, contact your carrier's customer service by phone, chat, or their mobile app. Tell them you have a new iPhone and need to transfer your eSIM. They will ask for your account details and the phone number associated with the plan.

The carrier will deactivate the eSIM on your old device and send you a new eSIM for your new iPhone. This usually arrives as a QR code via email, text, or through their app within a few minutes. On your new iPhone, go to Settings > Cellular > Add Cellular Plan and scan the QR code, or tap the link in the email or text message. The new eSIM will activate within a few minutes.

Some carriers charge a small fee (typically $5 to $15) to issue a replacement eSIM, though many waive this if you explain the situation. Ask before they process the request.

Use your carrier's app or website to manage your eSIM

A growing number of carriers let you transfer or manage eSIMs through their own app or website without calling. Open your carrier's app on any device, look for a section labeled eSIM, Manage SIM, or Switch Devices, and follow the prompts to transfer to your new phone or request a new eSIM code.

This method is often faster than calling, and you can do it at any time — you do not have to wait for a representative. Check your carrier's support page or app to see if this option is available for your account. If you cannot find it, calling customer service remains the reliable backup.

What to do if the transfer fails or gets stuck

If the transfer does not complete during setup, or if you see an error message, restart both phones and try again. Make sure both phones are connected to the same Wi-Fi network or have cellular service, because the transfer needs a data connection.

If restarting does not work, cancel the transfer on the new phone and contact your carrier instead. Ask them to deactivate the eSIM on your old phone and send you a new one. This is more reliable than troubleshooting the transfer process, and it usually takes only a few minutes.

If your carrier's system shows the eSIM is still active on both phones, the old phone will not have service — the new phone takes priority. In this case, the carrier can manually deactivate the old one and reactivate the new one.

Switching between an eSIM and a physical SIM card

If you want to use a physical SIM card instead of an eSIM on your new iPhone, contact your carrier and ask them to send you a physical SIM. You will need to deactivate the eSIM first — most carriers do this automatically when you request a physical SIM replacement.

The physical SIM arrives by mail in a few days. When it arrives, insert it into the SIM tray on your new iPhone and follow the carrier's activation steps. Your old eSIM will no longer work once the physical SIM is activated on your account.

You can also switch back from a physical SIM to an eSIM by contacting your carrier and requesting a new eSIM code. This is useful if you want to use multiple plans on the same phone or if you plan to travel and want to add a local eSIM temporarily.

Frequently Asked Questions

Can I transfer my eSIM if my old iPhone is turned off?

No. Both phones must be powered on and connected to Wi-Fi or cellular data for the transfer to work. If your old phone is off or unavailable, contact your carrier and ask them to issue a new eSIM for your new device instead.

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

No. Your phone number stays the same throughout the transfer. The eSIM is just a new copy of your existing plan on a different device.

How long does it take to transfer an eSIM?

During setup with both phones present, the transfer usually takes one to two minutes. If you request a new eSIM from your carrier, it typically arrives within a few minutes to an hour, depending on how they send it (email, text, or app).

Can I use my old iPhone after I transfer the eSIM?

Your old iPhone will lose cellular service on that plan once the transfer completes. It can still use Wi-Fi calling and Wi-Fi data if you set those up beforehand. If you want to keep the old phone on a different plan, ask your carrier about adding a second line.

What if my carrier does not support eSIM transfers?

Most major carriers now support eSIM transfers, but some smaller carriers or MVNOs may not. Contact your carrier to confirm they offer eSIM service. If they do not, ask about switching to a physical SIM card or changing carriers.
