What is Profile transfer?
It works only when both devices support it and the provider allows it. Many travel plans do not, leaving a re-issue as the only route, so check before swapping phones mid-trip.
Profile transfer is an operating-system feature that moves an eSIM profile from an old handset to a new one without scanning a fresh QR code or asking for another installation file. It sounds like moving photos or apps, but it is considerably more involved, because a profile is not an ordinary file. It is a network identity bound to a security chip inside the phone, and moving it requires consent from more than one party.
This page sets out who has to support the feature, why so many travel plans cannot be transferred, what to check before changing phones, and what routes remain when a transfer is impossible. Menu names and the location of the feature differ by manufacturer and by operating-system version, so we describe the principles that hold on any handset rather than listing menu paths that would go stale within a season.
A profile is not a file you can copy
An eSIM profile behaves like a plastic SIM that has been written into a chip inside the phone instead of slotted into it. The chip holds the keys used to prove identity to the network, and those keys are designed to live in exactly one place and never be duplicated. The reason is straightforward: if they could be copied, two handsets could claim to be the same subscriber at the same time. The whole system is built to prevent that.
A transfer, then, is not a copy but a move. The profile has to be deactivated on the old device and reissued on the new one, with the provider's systems involved behind the scenes. That is why a transfer needs an internet connection, and why a provider is in a position to refuse: the process runs on their platform, not merely between two phones sitting side by side on a table.
Three parties that all have to agree
A transfer succeeds only when all three parties support it: the source handset, the destination handset, and the provider that issued the profile. If any one of them does not, the feature either never appears or appears and then fails partway through. Most people check only one of the three, the new phone, and conclude that it should work — which is where the disappointment on switching day comes from.
| Party involved | What has to be true | How to check |
|---|---|---|
| The old handset | Must support eSIM and carry the transfer feature in the OS version installed | Look in the mobile network settings for an option to move or transfer a profile |
| The new handset | Must support eSIM, and usually needs to run the same family of operating system | Check the model's specification, or use our device checker |
| The provider that issued the profile | Must permit that profile to be transferred, which is a policy decision on their side | Read the plan terms, or ask before buying when they are silent on it |
| An internet connection during the transfer | Needed throughout, because the systems have to talk to the provider | Line up reliable Wi-Fi before starting; do not attempt it while on the move |
Every condition has to hold at once. If one is missing, the transfer will not happen.
Why many travel plans cannot be transferred
A great many travel plans issue a profile tied to the handset it was first installed on, and were never designed to be moved around. The practical reasoning is that these plans are short-lived, inexpensive, and meant to be used up on a single trip. Allowing free transfers adds complexity in the back-end systems and more ways for things to go wrong, so plenty of providers simply do not offer it.
For the traveller, the consequence is that changing phones mid-trip may leave the profile behind on the old one, and the remaining route is to ask for a reissue. Some providers will do that, some will do it with conditions attached, and some will not do it at all. This is worth knowing before departure rather than while standing outside a repair shop abroad with a new handset in hand.
What to check before switching handsets
Checking ahead takes only a few minutes and removes almost all of the problems that are hardest to fix later. The sequence below runs in order of importance. The first item is the one most often skipped, and the only one you cannot answer by looking at the phone, because it depends on the policy of whoever issued your profile.
- 1Confirm with the provider whether this profile can be transferredRead the plan terms first. If they are silent, ask before doing anything. Do not infer from experience with a different plan, because the policy can differ even within the same provider's range.
- 2Check that the destination handset supports eSIMSome regional variants of a model leave the feature out or use different components, so the model name alone is not always enough. Our device checker helps confirm it.
- 3Update both handsets before you beginThe feature has been added to and refined in newer OS releases, so bringing both sides up to date reduces the chance of the menu simply not appearing. Do it on home Wi-Fi, not mid-trip.
- 4Line up a reliable connection for both phonesDuring the process both devices need to reach the provider's systems. A connection that drops midway can leave the profile in a stuck state that takes support to unwind, so do this where the Wi-Fi is steady.
- 5Keep the purchase email and reference number to handIf a reissue becomes necessary, this is the first thing anyone will ask for. Saving it in a note on the new phone, or as a screenshot, makes that day much shorter.
- 6Keep the old handset until the new one is genuinely workingDo not wipe, sell, or trade it in until calls, messages, and data all work on the new phone. In that window the old handset is the best fallback you have.
Transfer versus fresh installation
When a transfer is not possible, the alternative is installing a profile on the new phone — either one the provider reissues, or an entirely new plan. The two routes differ in time, in cost, and in what happens to whatever data was left on the original plan, so it is worth understanding the difference before choosing rather than trying each in turn under pressure.
| Point | Transferring the profile | Installing a new profile |
|---|---|---|
| Does it need the provider's permission? | Yes, because the process runs on the provider's systems | Yes for a reissue of the same plan, no if you simply buy a new one |
| Data remaining on the old plan | In principle it travels with the profile that was moved | Depends on policy: sometimes the balance carries across, sometimes not |
| Time it takes | Usually quick when all parties support it and the connection is steady | Slower, since you have to request one and wait for it |
| Main risk | Getting stuck partway if the connection drops, or the menu not appearing at all | A possible extra cost, and the time spent waiting |
| When it fits | A planned upgrade at home with Wi-Fi ready | A broken or lost phone, or an unplanned swap mid-trip |
The real outcome depends on each provider's policy. Always check against your own plan first.
Swapping phones in the middle of a trip
Changing handsets while travelling is the hardest version of this, because every condition that ought to be in place is missing. There may be no steady Wi-Fi, no purchase email within reach, and a limited window before you have to move on. Avoid it where you can. Where you cannot, following the right order at least reduces the chance of losing the profile for nothing.
- Find steady Wi-Fi before starting; do not attempt it in a moving vehicle or on foot
- Open the purchase email and save the reference on the new phone first
- Verify the transfer option actually exists in the old phone's menus before planning around it
- Do not delete the original profile until everything works on the new phone
- Keep your home SIM available as a fallback route for verification codes
- If it stalls, stop and ask rather than experimenting until the state is stuck
A phone that is lost or suddenly broken
Once the old handset is unusable, the ordinary transfer route closes, because the process has to begin on the source device. What remains is asking the provider to reissue the profile. Whether they will, and whether there is a charge, depends on their policy. The details worth having with you are the purchase email, the order reference, and the plan name.
The lesson that applies to everyone is not to keep the proof of purchase on one device only. Forwarding the email to an account you can open elsewhere, or saving the reference somewhere reachable from a computer, shortens this situation considerably. People who have done that usually resolve it the same day; people who have not usually wait until they are back somewhere with a computer.
Planning ahead of a handset upgrade
If you know a new phone is coming soon, order the steps sensibly. The smoothest route is to complete the switch before travelling and then install the travel plan on the new handset. That removes the transfer question entirely, since there is nothing to move, and it lets you confirm the new phone handles the profile while you are still at home.
If the change has to happen after the plan is installed, treat the transfer as something to confirm rather than something to expect. Check all three parties as described above, and allow more time than you think you need. Swapping phones the night before a flight is the worst possible moment, because if anything goes wrong there is no time left to fix it.
Why the transfer option may not appear at all
The question we field most often here is that the transfer option cannot be found on the phone at all. There are several possible reasons and none of them means the handset is faulty. First, the installed operating-system version may not carry the feature yet. Second, the wording differs by manufacturer — one calls it moving a SIM, another calls it transferring a profile, and a third tucks it under the entry for that particular SIM. Third, the profile itself may have been issued in a form that cannot be moved, in which case the option is simply never offered.
A workable sequence is to update to the newest operating-system release the phone supports, then open that profile's own entry in the mobile network settings. If nothing to do with moving it appears, treat the route as closed for that plan and switch to planning around a reissue. What you should not do is delete the profile in the hope that the menu will surface afterwards; the result is a lost profile and nothing gained.
If you are unsure, ask before acting
Questions about profile transfer are hard to answer from a general web page, because the answer depends on the exact plan you hold and the two handsets in front of you. If you are unsure, send us the plan name, the old model, and the new model, and we will check whether that plan's conditions allow it.

Česta pitanja
Does profile transfer work with every plan?+
No. The feature needs support from the source handset, the destination handset, and the provider that issued the profile. Many travel plans do not support it, because the profile is tied to the device it was first installed on. Check your plan's terms before switching, or send us the plan name and we will check.
Can a profile be transferred between different operating systems?+
The transfer features built into operating systems are generally designed to work within the same family, so moving between different systems usually means installing afresh instead. If you are changing platform, plan on the assumption that a new profile will be needed, and check in advance whether the provider will issue one.
If I have already deleted the profile, can it be recovered?+
Generally not on your own. A profile deleted from a device usually cannot be restored, and whether a replacement is issued is the provider's decision: some will under conditions, some will not. If it has happened, gather the purchase email and order reference and contact us as soon as you can so we can take it up under whatever terms apply.
Is an internet connection required during the transfer?+
Yes. The step is not a file copy between two phones; it involves the provider's systems deactivating one profile and activating another. Do it where the Wi-Fi is steady rather than while travelling or in patchy coverage, because a drop partway can leave a state that support has to clear.
Should I change phones before or after buying the plan?+
Where you have the choice, finish the handset change first and then buy and install the plan on the new phone. That order removes the transfer question entirely and gives you time to test the new device at home. If the change has to come afterwards, check the transfer conditions first and do not delete the original profile until the new phone is fully working.
