How to transfer an eSIM to another phone without losing anything
You’re switching to a new smartphone and your number is now on an eSIM. Good news: since the iPhone XS was launched in 2018, almost all recent models can handle this format without a physical SIM card. The question is no longer ‘is it possible’, but ‘how do you do it properly’. Here’s the full guide, tested on both iPhone and Android.
Understanding what an eSIM is before transferring it
An eSIM is a SIM card built directly into the phone. You don’t remove it; you programme it remotely. In practical terms, your mobile operator stores your profile on a chip soldered to the motherboard.
The direct consequence is that you cannot simply ‘slip’ an eSIM from one device to another like a nano-SIM. You need to transfer the digital profile, either by moving it from one phone to another or by reactivating it via your network operator. To get to grips with the basics, this guide to installing an eSIM with Holafly sets out the essential information you’ll need before you get started.
How to transfer an eSIM to another phone: the 3 methods
There are three reliable ways to do this. The choice depends on your devices and your mobile network provider.
- Direct device-to-device transfer: the quickest method, between two recent phones of the same make.
- The new network operator QR code: the safe bet when automatic transfer fails.
- Reactivation via the customer portal: useful if you’ve lost your old phone.
On iPhone: quick transfer between devices
Apple offers a virtually automatic transfer from iOS 16. Keep both iPhones switched on, unlocked and close to each other.
- On the new iPhone, open Settings, then Mobile Data.
- Tap Add eSIM, then Transfer from a nearby iPhone.
- Confirm on the old iPhone when the request appears.
- Enter the verification code and wait for activation.
If the option does not appear, your mobile network operator does not support direct transfer. Switch to the QR code.
On Android: transfer via settings
The method varies slightly depending on the brand, but the process remains the same on Android 13 and later versions.
- Open Settings, then Connections or Networks & Internet.
- Select SIM Manager, then Add an eSIM.
- Select Transfer a SIM from another device.
- Use your old phone to scan the QR code displayed, then follow the instructions.
On recent Google Pixel and Samsung Galaxy models, this transfer works very well. On older models, this option may not be available.
The universal method: request a new QR code
This is the solution that almost always works. Contact your mobile network operator or use their app. Request that your eSIM be reissued.
You’ll receive a new QR code, usually by email or via your customer portal. You then simply scan it on your new phone, via the ‘Add eSIM’ menu. The old profile is then automatically deactivated.
Mistakes to avoid during the transfer
An eSIM transfer rarely fails, unless you rush it. There are three common pitfalls.
- Deleting the old phone too soon: wait until the line is working on the new device before resetting anything.
- Reusing an old QR code: a QR code that has already been activated is usually no longer valid. You’ll need a new one.
- Forgetting about Wi-Fi: activation requires a stable internet connection, which is essential when travelling.
This last point is doubly important when travelling. Before setting off on a long journey, such as a cycling adventure in the Alps, test your connection at home. Also think about the rest of your kit, such as the equipment for high mountain passes, which you should always prepare before setting off.
FAQ: putting an eSIM on another phone
Can I transfer an eSIM between an iPhone and an Android?
Yes, but not via automatic transfer, which is only available for devices of the same brand. Ask your mobile network operator for a new QR code, then scan it onto the destination phone.
Will I lose my number when changing devices?
No. The transfer moves the profile, not the number. Your number will remain the same once the eSIM is active on the new phone.
Is there a charge for transferring an eSIM?
It depends on the mobile network operator. Some offer the service free of charge, whilst others charge a few euros. Check the charges in your customer portal before starting the process.
How long does the process take?
Allow five minutes on average for a direct transfer. Reissuing via a QR code may take a little longer, whilst you wait to receive the code.
What should I do if my old phone is broken or lost?
A direct transfer will not be possible. Contact your mobile network operator to have the eSIM profile completely reissued onto your new device.
