An eSIM that will not transfer to a new iPhone is usually a travel eSIM rather than a carrier eSIM, and most travel profiles are bound to the device that installed them. Apple’s eSIM Quick Transfer only moves lines a supporting carrier has enabled for transfer, so the first question is not how to fix the transfer but which kind of line you are holding.
This page separates the two cases, lists the specific conditions that break a carrier transfer, and gives the safe sequence for moving a travel plan without losing it.
In this guide:
- First, identify which kind of eSIM you have
- Why carrier transfers fail
- Why travel eSIMs usually cannot transfer
- The safe sequence for moving a travel plan
- Transferring without the old phone
- Setting up a new iPhone mid trip
- What not to do
- If a reissue is not available
First, identify which kind of eSIM you have
Two very different products share the word eSIM, and every piece of transfer advice depends on which one you are moving.
| Carrier eSIM | Travel eSIM | |
|---|---|---|
| What it is | Your normal phone line, delivered as an eSIM instead of a plastic SIM | A prepaid data plan for a trip |
| Has your phone number | Yes | Usually no, most are data only |
| Billed | Monthly, by your home carrier | Once, before use |
| Transferable between phones | Usually yes, via Quick Transfer, if the carrier supports it | Usually no, profile is bound to the device |
| If transfer is impossible | Carrier issues a new eSIM from your account | Provider reissues, or you buy a new plan |
If the line carries your everyday phone number and appears on a monthly bill, it is a carrier eSIM and Quick Transfer applies. If you bought it for a trip and it only carries data, it is a travel eSIM and the rest of this page’s second half applies.
Why carrier transfers fail
When Quick Transfer is available but not working, the cause is nearly always one of these.
- Bluetooth is off on one device. Quick Transfer uses a direct link between the two phones. Both need Bluetooth enabled and the phones close together.
- One iPhone is on an older iOS version. The feature needs recent iOS on both ends. Update both before trying again.
- The carrier has not enabled transfer for your line. This is a carrier side switch, not a phone setting. If the option does not appear at all, this is usually why.
- The old phone is locked, off, or not signed in. Both devices must be unlocked and awake during the transfer.
- The line is a business or prepaid account with transfer restrictions. Some account types are excluded by the carrier.
Apple documents the supported setup flow in its eSIM setup guide, and where Quick Transfer is not offered the answer is always the same: ask the carrier to issue a new eSIM for the new device. They can do it from your account without the old handset.

Why travel eSIMs usually cannot transfer
A travel eSIM profile is downloaded once, using a single use activation code, onto one device’s secure element. There is no equivalent of Quick Transfer for it, because the transfer feature is something a carrier enables for its own subscriber lines rather than a general capability of eSIM.
That leaves three realistic outcomes when you change phones mid trip.
- The provider reissues the profile. Many will, usually once, with remaining data intact. This is the outcome you are aiming for and it starts with a support message, not a deletion.
- The provider cannot reissue. Some cannot, because the constraint sits with the network rather than the seller. You buy a fresh plan for the new phone.
- You delete the old profile first and then discover neither of the above applies. This is the outcome to avoid, and it is entirely preventable.
The safe sequence for moving a travel plan
- Keep the old phone and the old profile intact. Do not delete anything yet.
- Message the provider with your order reference, the new device, and how much data and validity remain.
- Wait for their answer. If they reissue, you will get a new QR code or install link.
- Install the new profile on the new phone over Wi Fi, then confirm it connects.
- Only then remove the old profile, if the provider asks you to.
If the answer is no reissue, the practical move mid trip is to buy a small plan for the new phone to cover the remaining days rather than trying to recover the old one. Prices by country are on the destinations index, and the cheapest eSIM plan guide covers sizing a short replacement without overpaying.
Transferring without the old phone
If the old phone is lost, broken or already traded in, Quick Transfer is off the table because it needs both handsets. The route is through the account instead.
- Carrier line. Contact the carrier and request a new eSIM for the new device. They can issue it from your account, usually through their app or a store, and the old profile is deactivated in the process.
- Travel eSIM. Contact the provider with your order reference. Reissue is discretionary, and having the order email makes it far more likely to go smoothly.
If the phone was lost rather than replaced, work through what to do when you lose a phone abroad first, because securing the accounts matters more than recovering the data plan.
Setting up a new iPhone mid trip
Changing phones while abroad adds one complication the advice above assumes away: you may have no working data connection on either handset while you sort it out.
Three things make that manageable. Do the whole process on Wi Fi, because both the provider conversation and any reissued profile need an internet connection that does not depend on the plan you are fixing. Keep the old phone powered on and connected until the new line works, so you retain a route to email and messaging while you wait. And check your home carrier line separately, because on a new iPhone that line may also need reissuing and it is the one carrying your bank verification codes, as covered in bank OTP SMS codes abroad.
If the new phone is a replacement for a lost one rather than an upgrade, do those account security steps before the connectivity ones.
What not to do
Do not delete the eSIM from the old phone to free it up. Deletion is permanent on iPhone and the profile is usually not reinstallable from the same code. This single action turns a solvable problem into a lost plan more often than anything else in this guide.
Do not scan the original QR code on the new phone. Single use codes are consumed by the first successful install. Rescanning either does nothing or, worse, leaves the network pointing at an installation that no longer exists, which produces the eSIM not provisioned error.
Do not factory reset either phone to fix a transfer. No transfer failure in this guide is caused by anything a reset addresses.
Set up on the new phone, the general checklist in the complete troubleshooting guide covers what to verify once the line is installed, and the device compatibility checker confirms the new handset supports eSIM before you start.
If a reissue is not available
When a provider cannot move a travel plan to the new phone, buying a short plan for the remaining days beats spending the trip offline, and it is usually a small amount of money.
Viasimo sells prepaid plans in sizes small enough to cover a few remaining days as well as a full trip, delivered by email in minutes as a QR code you scan in your new phone’s settings. There is no app to install, no account required before you can see prices, and nothing renews afterwards. The plan is data only, so the number on your carrier line is unaffected by any of it.
Size it to the days you have left on the destinations index, or go direct to the USA, Europe or Japan.
You can also skip the reading and start at the eSIM plan picker: pick the country, pick the number of days, and compare every plan that covers it.
