Getting a new phone used to mean moving a small plastic card between two trays. eSIMs removed the card, and with it the obvious way to move your number across. The good news is that phones now have a built-in transfer flow for exactly this. The less good news is that it doesn't cover every kind of eSIM, and the one it doesn't cover is the one travellers tend to be holding. This guide separates the two cases, because they have genuinely opposite answers: your carrier line can usually be moved in a couple of minutes, while a travel data plan that has already been activated generally cannot be moved at all. Knowing which one you're dealing with before you factory-reset anything will save you the worst version of this problem.
Start by working out which eSIM you're moving
Almost all the confusion here comes from two different products sharing a name. Both are eSIMs, both live in the same chip, and the rules for moving them are not the same.
The first is your carrier line: the eSIM from your home mobile network that carries your phone number, the one you make calls and receive texts on. Moving this to a new phone is a normal, supported thing to do, and both Apple and Android have built flows for it.
The second is a travel data plan: a prepaid eSIM bought for a trip, data-only, with no phone number attached. This one is bound to the device it was installed on. Once it has been activated, it generally cannot be moved to a different phone at all.
If you're not sure which you're looking at, check whether it has a phone number and whether you bought it from your usual carrier or from a travel provider. The rest of this guide assumes you've made that distinction, because following the wrong set of instructions is how people end up deleting something they can't get back.
Moving a carrier eSIM to a new iPhone
Apple builds this into the setup process. When you switch on a new iPhone next to your old one, the setup assistant will usually offer to bring your cellular plan across as part of Quick Start, and accepting is the whole job. Keep both phones on, unlocked and near each other while it runs.
If you've already finished setup, you can still do it afterwards. On the new iPhone go to Settings, Cellular, then Add eSIM, and choose the option to transfer from another iPhone. Your old phone will show a confirmation prompt, and approving it moves the line across. Both devices need Bluetooth on and need to be close together.
The transfer deactivates the line on the old phone as part of the process, which is the correct behaviour rather than a fault: a mobile number can only be live on one SIM at a time. Expect a short gap with no service on either handset while the network catches up.
The one dependency worth knowing about is that your carrier has to support this. Most large networks do, but not all of them, and support can vary by plan type and by country. If the option doesn't appear or the transfer is refused, that's your answer, and the fallback is to ask your carrier to reissue the eSIM for the new device.
Moving a carrier eSIM on Android
Android is less uniform, because the flow depends on the manufacturer, the Android version and the carrier all at once. Recent Pixel and Samsung devices support transferring an eSIM between phones, and the option generally appears during initial setup or under the SIM settings afterwards.
The practical approach is to look for it during setup first, since that's where it's most likely to be offered, and to check the SIM or network section of settings if you've already passed that point. Where it exists, the flow mirrors Apple's: confirm on the old device, wait, and the line moves.
Where it doesn't exist, the reliable route is your carrier. They can deactivate the profile on the old device and issue a fresh one for the new phone, usually through their app or by sending a new QR code. This is slower than a device-to-device transfer but it works regardless of what your handsets support.
Because the experience varies so much, avoid wiping or trading in the old phone until the new one is actually connected and making calls. That advice sounds obvious and is routinely ignored.
Travel eSIMs: the honest answer
A travel eSIM that has been installed and activated cannot be transferred to a different phone. This is a real limitation rather than a policy we'd prefer, and it's better to know it before you upgrade than after.
The reason is in how the profile is delivered. Your install link or QR code is a one-time activation code, and redeeming it downloads the profile into that specific phone's secure element. The code is then spent. There's no second download waiting to be claimed by another device, and the profile itself can't be copied out of the chip it landed in.
The practical consequence is straightforward. If you switch phones part-way through a trip, the plan stays on the old handset. If the old handset still works, you can keep using it for data and hotspot from it to the new one, which is an inelegant but effective workaround. If it doesn't, you'll generally need a new plan for the new phone.
Because of this, an eSIM is worth installing on the phone you're actually travelling with, not on whichever device is nearest when the email arrives. It's a small thing that prevents an annoying one.
If you haven't installed it yet, you're fine
This is the case people worry about unnecessarily. An eSIM you've bought but not yet installed isn't tied to anything. The activation code hasn't been redeemed, so it will install on whichever phone redeems it first.
So if you bought a plan for an upcoming trip and then changed phones before installing, simply install it on the new one. Nothing needs to be cancelled, reissued or explained to anyone. The same is true if you originally scanned the QR onto a phone you've since decided not to travel with, as long as you never actually installed the profile.
This is also the strongest argument for the standard advice to install before you fly but only enable the line on arrival. Installing early on the right device gets the download done over reliable home Wi-Fi, while the validity clock still waits for the first connection at your destination.
If the install link from your original email has expired, that's not a problem either. Links are time-limited by design, and you can request a fresh one rather than assuming the plan is lost.
If your old phone is broken, lost or already wiped
For a carrier line, this is a solved problem and you should contact your network. They can suspend the line on the old device and issue a replacement eSIM for the new one, which is the same process they've always run for a lost SIM card. You don't need the old handset in your possession for this.
For a travel eSIM, the answer depends entirely on whether it was ever activated. If it wasn't, the code is still unredeemed and you can install it on the new phone as described above. If it was, the profile went into a device you no longer have, and there's usually nothing to recover.
It's still worth contacting support rather than assuming, because what can be done depends on how much of the plan is left and what state the order is in. Have the email address you ordered with to hand, since that's what identifies the order.
If you deleted the profile from a phone you still own, that's a different and much better situation. A deleted eSIM can usually be reinstalled on the same device from its original install link or QR code, provided the plan is still valid, still active and still has data left. All three conditions matter.
Before you upgrade: a five-minute checklist
Most transfer problems are created in the twenty minutes before the transfer, usually by someone being efficient and resetting the old phone early.
The single rule that prevents nearly all of them is to keep the old phone working and in your hands until the new one is fully live. Everything else is detail.
- Don't factory reset or trade in the old phone until the new one is making calls
- Check whether your carrier supports device-to-device eSIM transfer before you start
- Move your carrier line first, then deal with any travel plans separately
- Note which travel eSIMs are activated — those are the ones that won't move
- Install any not-yet-used travel eSIMs onto the new phone, not the old one
- Keep the order confirmation emails for any travel plans you still have running
- Do the whole thing on Wi-Fi, since a transfer briefly leaves you without mobile service
When a transfer fails
If the transfer option never appears on either phone, the usual explanation is carrier support rather than anything you've done wrong. Check with your network, and use their reissue process instead. It ends in the same place.
If the transfer starts and then fails, the most common causes are mundane: Bluetooth off, the phones too far apart, one of them locked, or a weak connection during the handover. Put both phones on the same Wi-Fi, unlock both, keep them side by side and try once more before escalating.
If you've ended up with no service on either handset, don't keep retrying. Restart both phones first, because the network needs a moment to register the change and a restart often resolves what looks like a failed transfer. If service still hasn't returned on the new phone after that, your carrier can push the profile again from their side.
And if the line moved successfully but data doesn't work, that's usually not a transfer problem at all. Check that the new phone has the right line set as its data line, and that data roaming is set the way you need it. Those are separate settings that don't always follow a line across.
Frequently asked questions
Can you transfer an eSIM to a new phone?
It depends which eSIM. A carrier line carrying your phone number can usually be transferred, and both iPhone and recent Android phones have a built-in flow for it, subject to your carrier supporting it. A travel data eSIM that has already been activated generally cannot be transferred to a different device, because the activation code is single-use and the profile is tied to the phone that downloaded it.
How do I transfer my eSIM to a new iPhone?
The easiest moment is during setup: place the new iPhone next to the old one and the setup assistant will usually offer to bring your cellular plan across. If setup is already done, go to Settings, Cellular, Add eSIM on the new iPhone and choose the option to transfer from another iPhone, then approve the prompt on the old handset. Keep both phones unlocked, nearby and with Bluetooth on.
How do I transfer an eSIM on Android?
It varies by manufacturer, Android version and carrier. Recent Pixel and Samsung devices support eSIM transfer, and the option usually appears during initial setup or in the SIM section of settings. If you can't find it, your carrier can deactivate the old profile and issue a new one for your new phone through their app or a fresh QR code.
Can I transfer a travel eSIM to a new phone?
Not once it's been activated. A travel eSIM installs on one device only, and the activation code is spent once redeemed, so there's no second download for another phone to claim. If you haven't installed it yet, there's no problem at all: just install it on the new phone instead.
What happens to my travel eSIM if I get a new phone mid-trip?
The plan stays on the old handset. If that phone still works, the practical workaround is to keep using it for data and share the connection to your new phone over hotspot. If it doesn't work, you'll generally need to buy a plan for the new device. Contact support with your order email before assuming, since what's possible depends on the plan's remaining data and validity.
Can I transfer an eSIM if my old phone is broken?
For a carrier line, yes. Contact your network and they'll suspend the old profile and issue a replacement for the new phone, exactly as they would for a lost SIM card. You don't need the old device. For an activated travel eSIM, usually no, because the profile lives in a phone you can no longer reach.
Do I need my old phone to transfer an eSIM?
For a device-to-device transfer, yes. Both phones need to be on, unlocked and close together, because the old one has to confirm the handover. If your old phone is unavailable, skip the device-to-device route entirely and ask your carrier to reissue the eSIM for the new handset instead.
Does transferring an eSIM delete it from the old phone?
Yes, and that's intended. A phone number can only be live on one SIM at a time, so the transfer deactivates the line on the old device as part of moving it. Expect a short period where neither phone has service while the network registers the change.
Can I reinstall an eSIM I deleted by mistake?
Usually, if it's the same phone. A deleted eSIM can generally be reinstalled on the same device from its original install link or QR code, as long as the plan is still valid, still active and still has data left. All three conditions have to hold. It cannot be reinstalled onto a different phone once it's been activated.
Can I use the same eSIM on two phones at once?
No. An eSIM installs on a single device, and the activation code only works once. If you need data on a second phone, tablet or laptop, either share the connection over hotspot or buy a separate plan for it.
Does an eSIM transfer automatically when I restore from a backup?
Don't count on it. Restoring a backup brings your apps and data across, but the eSIM profile is stored in the phone's secure element rather than in the backup. iPhone setup may offer to transfer the plan as a separate step during the process, which is worth accepting when it appears, but treat the cellular line as something you move deliberately rather than something a restore handles for you.
What if my carrier doesn't support eSIM transfer?
Then use their reissue process, which every carrier offering eSIM will have. They deactivate the profile on your old device and provide a new one for the new phone, typically in their app or as a QR code. It takes longer than a device-to-device transfer but the end result is identical.
Can I transfer an eSIM to a different network?
That isn't a transfer, it's a switch. An eSIM profile belongs to the network that issued it and can't be moved to a different carrier. What you can do is keep your phone number and move it to a new network, which is the normal number-porting process, and the new carrier will then issue you their own eSIM.
How long does an eSIM transfer take?
A device-to-device transfer typically takes a couple of minutes, plus a short gap while the network registers the change and service returns on the new phone. A carrier reissue can take longer depending on how quickly they process it. In both cases, don't wipe the old phone until the new one is confirmed working.
