Ever wondered how to transfer an eSIM to a new phone or only just realised why it’s so important to do? eSIMs are still relatively new, so whether you’re switching to a new iPhone or moving between Apple and Android, transferring an eSIM correctly is crucial so you don’t lose mobile service.
In this blog, we’ve outlined a step-by-step guide that you can follow when transferring your eSIM to a new phone. The process is fairly quick and simple, and will ensure your data is moved across properly. Just check beforehand if your carrier supports the transfer as it’s essential.
Jump to the relevant section:
First things first, before you jump into transferring your eSIM, it’s worth taking some time to make sure you have everything you need so all goes smoothly, regardless of whether you’re switching to a new iPhone or Android device.
1. Check that your carrier supports eSIM transfer
Not all networks allow automatic transfers between devices. In the UK, major providers including EE, O2, Vodafone and Three support eSIM, but some transfers may still require a QR code or activation code.
2. Make sure your new phone supports eSIM
Head to Settings and look for an option like ‘Download a new eSIM’ to confirm compatibility.
For iPhone: Settings → Mobile Service
For Android: Settings → Network & Internet
3. Connect both phones to Wi-Fi
Both devices will need a stable internet connection to complete the transfer. Checking this beforehand will save you time and ensure you don’t have to start again.
4. Update your software
Make sure both phones are running the latest version of iOS or Android, as eSIM transfer features require updated software.
If you’re worrying about transferring your eSIM between iPhones, Apple’s built-in eSIM Quick Transfer makes it simple - and in many cases, you don’t need to contact your carrier. Make sure you're running the latest iOS 26 so the transfer goes smoothly.
Turn on your new iPhone and place it near your old iPhone.
Ensure both devices are connected to Wi-Fi and signed in with the same Apple ID.
On your new iPhone, go to Settings.
Tap on Cellular.
Add eSIM.
Choose Transfer From Nearby iPhone.
Confirm the transfer on your old iPhone.
Tap Activate to complete setup.
Once complete, your new iPhone will activate the eSIM and connect to your network.
Similar to iPhones, Android devices have a built-in eSIM transfer tool, supported by Google. This means you can transfer your eSIM to a new phone while setting it up for the first time.
Turn on your new Android phone.
Follow the on-screen instructions to the setup process.
Connect to Wi-Fi.
When prompted, choose Set up eSIM or Transfer SIM from another device.
Follow the instructions to complete the transfer.
NOTE: Some carriers may require you to scan a QR code instead.
If you’re transferring an eSIM between an Android and an iPhone, you’ll need some help from your carrier as it involves two different operating systems.
Contact your mobile phone provider and request new eSIM activation details.
Get your QR code or an activation code.
On your new phone, go to:
iPhone: Settings → Mobile Service → Add eSIM
Android: Settings → Network & Internet → Add eSIM.
4. Scan the QR Code or enter the Activation Code.
5. Follow the instructions on screen to complete the setup and activate the eSIM.
If you no longer have access to your old phone, don’t fret. You can request a new eSIM from your carrier. If you’re with one of the main UK providers listed below, you can request a new eSIM online or using their app.
🌐EE - Log into your ‘My EE’ account and request a new eSIM or QR code. You can also call EE customer service instead.
🌐O2 - Log into your ‘My O2’ or contact them directly through customer support. You will then receive your QR code via email or by post depending on your preference.
🌐Three - Log into your online account and click ‘replace SIM’ and choose eSIM. You will then get an email containing a QR code to scan and begin the transfer process.
🌐Vodafone - Log into your Vodafone app or call for support by dialling 191. They will then be able to issue you a new eSIM via email or direct you to a store.
Deleting an eSIM is pretty simple, especially since your phone can store up to eight eSIMs. Since only two of them can be active at a time, it’s worth knowing how to do it.
Go to Settings.
Click on Network & Internet.
Choose the eSIM you wish to delete.
Tap ‘Delete’.
Open the Settings menu.
Click on Mobile Service.
Scroll down, check to see if you have a single or multiple plans.
If you have a single plan, click ‘Delete eSIM'.
If you have multiple plans choose the plan you want to delete and then click ‘Delete’.
Transferring an eSIM to a new phone might sound technical at first, but as you can see, the process is usually quick and straightforward - especially if you’re moving between devices on the same operating system. Whether you’re upgrading to the latest iPhone, switching to a new Android, or moving between the two, the key is preparation: check compatibility, ensure your software is updated, and confirm your carrier supports eSIM transfers.
In most cases, built-in transfer tools make the switch seamless. And even if you don’t have your old device, your carrier can issue a new eSIM so you’re never without service for long.
As eSIM technology continues to replace traditional SIM cards, knowing how to manage, transfer, and delete your eSIM will make future upgrades much easier. Follow the steps outlined above, and you’ll be connected on your new device in no time. Don’t forget to trade in your old phone once you’ve finished the transfer.
