If your eSIM transfer is not working, one common cause is that the plan or carrier does not support moving that eSIM between phones. Some travel plans may be limited to one installation, so check your plan details and order instructions before you try again. Reinstalling is an option only when your eSIM.site order or install instructions confirm that a new install or replacement is available. Sort this out at home, on Wi-Fi, before you leave.
This guide explains why transfers fail, what to check on the new phone, and how to choose between transferring, reinstalling and buying a new plan.
Why is my eSIM transfer not working?
An eSIM is a digital profile, not a physical card. Moving it between phones is not a universal feature. Apple says Quick Transfer is available only with participating carriers, and Google notes that transfer behavior can vary by carrier. So a failed transfer can reflect plan support rather than a broken phone.
These are frequent reasons a transfer to a new phone does not complete:
- The plan may not allow it. Some travel plans may be limited to one installation. Your plan details and order page should say what is possible.
- The new phone may not support eSIM. Confirm this before anything else.
- The new phone may be carrier-locked. Check whether the lock status blocks adding a plan from another provider.
- The software may be out of date. Setup tools change between versions.
- There is no stable connection. Installation needs Wi-Fi or a hotspot, as Apple's setup guidance explains.
- The old eSIM was already deleted. Check your plan details to see whether a deleted profile can be installed again.
If you see a general eSIM not working message, read the full text on screen and write it down. It tells support what actually failed.
Check phone compatibility and carrier lock first
Before you troubleshoot anything else, confirm the new phone supports eSIM and is carrier-unlocked. Run the model through the eSIM device compatibility checker. Do this before buying or installing any plan.
iPhone: check the carrier lock
- Open Settings > General > About.
- Find Carrier Lock.
- Look for No SIM restrictions.
Apple says only your current carrier can unlock an iPhone, and unlocking can take several days. Start early. Our guide to using a travel eSIM on a locked iPhone covers the details.
Android: check the basics
Menu names vary by brand and software version. Look under Settings > Network & internet or Settings > Connections for a SIMs or SIM manager option. An option to add an eSIM suggests the phone supports it, but confirm with the compatibility checker and your carrier. Your carrier can also tell you whether the phone is unlocked.
What to try when a new phone eSIM setup stalls
Keep this short and methodical. Most failed attempts come down to a few prerequisites.
iPhone
Connect to Wi-Fi and update iOS. Then open Settings > Cellular (or Mobile Service) and tap Add eSIM. If your plan supports transfer from another iPhone, you will see that option. If not, use the QR code or manual details from your order. Labels vary by iOS version.
Apple says a number moved through Quick Transfer stops working on the previous iPhone. So do not delete the old eSIM or wipe the old phone until the new one is confirmed working.
Android
Google says automatic transfer needs Android 12 or later on both devices, current Google Play services and a screen lock. If the transfer is not detected, retry, then contact your carrier or provider. If your order confirms a QR code install, a common path on Galaxy phones is Settings > SIM manager > Add eSIM > Scan QR code. On other phones, look under Settings > Network & internet > SIMs. Menus vary by model.
A failed attempt does not always mean the plan is lost. Stop, leave the old phone as it is, and read what your order says about reinstalling.
Transfer, reinstall or buy new: which should you choose?
A device-level transfer option does not prove a specific travel eSIM can move. Treat each plan on its own terms. Check your order page and install instructions first.
| Approach | Works when | Main risk | Best for |
|---|---|---|---|
| Transfer to the new phone | The plan and carrier explicitly support it | The old phone may lose service once the eSIM moves | Travelers upgrading phones with a plan that allows transfer |
| Reinstall from original details | Your eSIM.site order or install instructions confirm a new install or replacement is available | Some plans may be limited to one installation | Travelers whose transfer failed and who still have the QR code and order email |
| Buy a new plan | Your order details and eSIM.site support confirm the old plan cannot be recovered | You may pay twice if the old plan was still usable | Travelers close to departure with no working option |
Do not assume a QR code can be scanned twice. Whether it can depends on the specific plan. If your order does not make it clear, contact eSIM.site support using the details in your order confirmation before you delete anything.
Keep your original QR code and install details
Apple documents both QR-code installation and manual entry when a provider supplies the details. Save everything you were sent:
- The original eSIM email and QR code, plus a screenshot on a second device or a printed copy.
- The manual activation details, if your plan provides them.
- Your order reference.
- The IMEI and EID of the phone you plan to use. On iPhone, find them under Settings > General > About.
- The exact error message, written down or screenshotted.
These details help you and support work out what happened. If the code is displayed on the same phone you are installing on, see how to install a travel eSIM QR code on the same phone.
A pre-trip checklist to avoid losing your plan
- Confirm compatibility and lock status on the phone you will actually carry.
- Update the phone and connect to reliable Wi-Fi.
- Save the QR code and details in more than one place.
- Keep the old eSIM until the new installation works.
- Check the validity start rule. Some plans start when the eSIM is installed, others on first connection in the destination. Read your plan details before installing early.
- Install before departure over Wi-Fi, so you are not relying on airport connectivity. See whether to install your eSIM before travel.
- Confirm the travel line appears under Cellular or SIMs, with a clear label such as "Travel".
- Set your lines. Keep your home line for calls and texts if needed, and turn on data roaming for the travel eSIM line only. Our guide on which line should have data roaming on explains the setup.
Hotspot sharing, speeds, top-ups and phone numbers all depend on the plan. Read the plan details instead of assuming.
What if the transfer fails after you are already abroad?
The same rules apply, but Wi-Fi access matters more. Do not delete anything until the new phone works. Our guide to moving an eSIM to a new phone mid-trip covers that situation in full.
When a new plan is the faster route
Buy a new plan only after you check your order details and ask eSIM.site support whether a replacement is possible. This step helps you avoid paying twice. If a replacement is not available, use the eSIM plan finder to match a plan to your destination. Confirm first that your phone is supported and unlocked.
If you are visiting several countries, these Global plans may fit. Check each plan's coverage and validity details before you buy.
Frequently Asked Questions
Why is my eSIM transfer not working on my new phone?
Common causes are plan or carrier limits, an unsupported or locked phone, outdated software and no stable Wi-Fi. Some travel plans may be limited to one installation, so a transfer may not be offered. Check your plan details.
Can I transfer a travel eSIM to a new phone?
It depends on the plan. Phone makers offer transfer tools, but they work only when the carrier or provider supports them. Check your plan details and order page before you try.
Will the old phone stop working after an eSIM transfer?
On iPhone, Apple says a number moved through Quick Transfer stops working on the previous iPhone. Keep the old phone intact until the new one is confirmed working.
Can I scan my eSIM QR code again?
Do not assume you can. Whether a code can be reused depends on the specific plan. Check the install instructions in your order, or contact eSIM.site support using the details in your order confirmation before you delete anything.
Is my eSIM not working because the phone is locked?
It can be a factor, so check. On iPhone, look at Settings > General > About for "No SIM restrictions" beside Carrier Lock. If the phone shows a restriction, ask your carrier to unlock it.
How long before a trip should I fix an eSIM problem?
As early as you can, ideally days before departure. Apple says carrier unlocks can take several days. You will also want Wi-Fi for installation and a spare day in case you need to reinstall or replace the plan.
