What happens when you move your eSIM to a new iPhone

An eSIM is a digital SIM card stored on your iPhone's chip rather than a physical card you insert. When you switch to a new iPhone, you move that eSIM by asking your carrier to transfer it, then confirming the transfer on your new phone. The process takes a few minutes to an hour, depending on your carrier.

The key difference from a physical SIM: you cannot straightforward move the chip to another phone. Instead, your carrier remotely deactivates the eSIM on your old iPhone and reactivates it on your new one. This means you need your carrier's help, and your old phone must be able to receive the deactivation signal before the transfer completes.

If you have multiple eSIMs on one iPhone (some carriers allow this), you can transfer them one at a time, or leave some behind and transfer only the one you want to use on the new phone.

Key Takeaways

  • Contact your carrier before you switch phones — they initiate the transfer and confirm your identity.
  • Keep your old iPhone powered on and near the new one during the transfer, because the old phone must receive the deactivation signal.
  • On your new iPhone, go to Settings > Cellular > Add Cellular Plan and follow the carrier's instructions to complete the transfer.
  • If the transfer fails, your carrier can resend the eSIM set up code, but this usually takes a second phone call.
  • Physical SIMs and eSIMs cannot be converted into each other — if you have a physical SIM, you must contact your carrier to switch to eSIM first.

Step-by-step: transferring your eSIM before you leave the old phone

Start this process while you still have both phones. Call your carrier's customer service line or use their app or website to request an eSIM transfer. Have your account number, phone number, and the new iPhone's IMEI number ready. You can find the IMEI on the new phone by going to Settings > General > About and scrolling to IMEI.

Your carrier will confirm your identity and send a confirmation code to your old iPhone via text or email. This is the moment your old phone must be powered on and able to receive signals. Once you confirm the code, your carrier deactivates the eSIM on the old phone and sends an set up code to your new iPhone.

Do not turn off your old iPhone until this step is complete. If the signal drops or the phone powers down before the deactivation signal arrives, the transfer can stall, and you will need to call your carrier again to restart it.

Completing the transfer on your new iPhone

On your new iPhone, open Settings, tap Cellular, then tap Add Cellular Plan. Your phone will search for available eSIM profiles. When your carrier's profile appears, tap it and follow the on-screen prompts. You may be asked to enter a confirmation code that your carrier sent via text or email.

Once you confirm, your new iPhone downloads the eSIM profile and connects to your carrier's network. This usually takes a few minutes. You will see a checkmark next to your carrier's name in the Cellular menu when the transfer is complete.

At this point, your old iPhone will lose service on that line. If you had a second eSIM on the old phone, it will still be active there until you transfer it separately using the same process.

What to do if the transfer stalls or fails

If your new iPhone does not show your carrier's profile after 10 minutes, restart the phone and check Settings > Cellular again. If it still does not appear, call your carrier and ask them to resend the set up code. They can send it via text, email, or a QR code you scan with another device.

If your old iPhone never received the deactivation signal (for example, if it lost power during the transfer), your carrier may need to manually deactivate the eSIM on their end before reactivating it on the new phone. This adds 15 to 30 minutes to the process but is straightforward once you explain what happened.

Some carriers allow you to transfer an eSIM through their app instead of calling. Check your carrier's website or app first — this route is often faster and does not require a phone call.

Transferring an eSIM when you no longer have the old iPhone

If you have already sold, recycled, or lost your old iPhone, you can still transfer the eSIM, but the process is slower. Call your carrier and explain that you no longer have access to the old phone. They will verify your identity using your account details, security questions, or a PIN you set up previously.

Once verified, your carrier can deactivate the eSIM on the old phone remotely without needing a signal from that phone. They will then send an set up code to your new iPhone. This usually takes one to two hours because your carrier must confirm you are not trying to fraudulently set up a line on a phone you do not own.

Have your new iPhone's IMEI ready when you call, and be prepared to answer security questions about your account.

Moving multiple eSIMs to a new iPhone

If you have two eSIMs on your old iPhone (for example, a personal line and a work line), you can transfer both to your new phone, but you must do them one at a time. Complete the full transfer process for the first eSIM, then repeat the steps for the second one.

Alternatively, you can transfer only one eSIM and leave the other on your old phone if you plan to keep using that phone as a secondary device. Your carrier will let you choose which eSIM to transfer when you call.

Your new iPhone can hold multiple eSIMs, but only one can be active at a time. You switch between them in Settings > Cellular by tapping the line you want to use.

Physical SIM to eSIM: what you need to know

If your old iPhone has a physical SIM card instead of an eSIM, you cannot transfer it directly to a new iPhone using the eSIM method. Instead, contact your carrier and ask them to convert your physical SIM to an eSIM. This is a separate process that takes one to three business days.

During the conversion, your carrier will deactivate your physical SIM and create a new eSIM profile linked to your phone number. Once the eSIM is ready, you can transfer it to your new iPhone using the steps above. Some carriers charge a small fee for this conversion, while others do it at no cost.

If you need service on your new iPhone before the eSIM conversion is complete, ask your carrier if they can issue a temporary physical SIM or set up a backup line while you wait.

Frequently Asked Questions

Do I need to contact my carrier before I start, or can I just move the eSIM myself?

You must contact your carrier first. The eSIM is tied to your account and your phone number, and only your carrier can authorize the transfer. Trying to add the eSIM on the new phone without carrier approval will not work.

What if my new iPhone is not activated yet and does not have service?

That is fine. Your new iPhone can receive the eSIM profile over Wi-Fi. Make sure it is connected to a Wi-Fi network before you start the transfer process on the new phone.

Can I transfer my eSIM to an iPhone owned by someone else?

No. Your carrier will ask for the new phone's IMEI and will only set up the eSIM on that specific device. If you try to transfer to a different phone, the set up will fail. You would need to contact your carrier and request a transfer to the correct phone.

How long does the whole transfer take?

If both phones are powered on and you have your carrier's confirmation code, the transfer usually completes in 5 to 15 minutes. If your carrier has to resend codes or manually deactivate the old eSIM, add 30 minutes to an hour.

Will I lose my phone number or service history when I transfer the eSIM?

No. Your phone number, plan, and billing history stay the same. The eSIM transfer straightforward moves your account's digital SIM profile to the new phone. Your carrier's records do not change.
