Quick Answer: Can You Transfer eSIM to a New Phone

The short answer is: yes, but it's not always easy. In many cases, what people mean by "eSIM transfer" is actually a carrier-controlled re-activation process.

• Some iPhones can automatically transfer your eSIM during setup
• Android devices usually need a QR code to activate
• Many carriers won't let you transfer directly because of security reasons
• Your phone number stays the same though

So even though the end result is the same, the process depends on your carrier and the brand of your phone.

How eSIM Transfer Actually Works

So what is an eSIM, anyway? It's not a physical thing you move from one device to another. It's just a digital version of your mobile plan.

When you switch devices, the system works kind of like this: the carrier checks to make sure you're who you say you are, they disconnect the old phone, and then they send a new activation profile to the new phone. And that profile gets downloaded and installed on your device.

That's why transfers can feel a bit hit and miss - the phone just requests activation, but it's the carrier who decides whether to automate it, do it manually, or just plain not let it happen. And the new phone has to be eSIM compatible for the whole thing to work.

iPhone to iPhone eSIM Transfer

Apple has made it pretty easy to transfer eSIMs between iPhones, as long as your carrier supports it.

When you set up your new iPhone, it might pick up your old iPhone nearby and offer to transfer your plan automatically - but only if your old phone is actually nearby and the transfer option appears on the Set Up Cellular screen. And on supported iPhones running iOS 16 or later, you can even do the transfer via Bluetooth. When it all works out, it's pretty seamless - your number just moves over to the new device.

What to do

Turn on your new iPhone, keep both devices close by, follow the on-screen instructions and confirm the transfer prompt on the Set Up Cellular screen. After a quick verification, the eSIM activates on the new device and switches off from the old one - but you should finish activating it before relying on the new phone.

But if the option doesn't show up, it's probably because your carrier needs you to do a manual setup with a QR code instead. That's not a problem - it just means automatic transfer isn't an option for your plan.

Android to Android eSIM Transfer

eSIMs work a bit differently on Android devices - depending on the brand and the carrier.

Some devices, like Google Pixel phones, have pretty smooth migration options, while others will need a QR code to get going. In most cases, you won't actually be "moving" the eSIM from one device to another - you'll just be installing a new one. And the end result is the same - service on the new phone - but the process is technically different.

Since Android is less standardised than iOS, the transfer process can vary a lot between brands and regions.

iPhone to Android eSIM Transfer

Switching from iPhone to Android can be a bit more complicated.

There's no universal way to transfer an eSIM directly from an iPhone to an Android device. What actually happens is that your carrier sends a new eSIM profile to the Android device.

What this looks like in real life is that your old eSIM gets deactivated and you get a QR code or activation link for the new device. You scan it and your number is back up and running on the Android device.

Even though it feels like a proper migration, it's actually just a reset-and-activate process.

Why eSIM Transfer Fails

When an eSIM transfer doesn't work, the problem is usually not with your phone - it's the carrier rules that are getting in the way.Common reasons for eSIM transfer issues include carrier restrictions that are put in place for security reasons & stop automatic transfers, or if your phone & eSIM don't play well together. Sometimes, travel eSIMs are only designed to work on 1 device & won't work on another once activated.

Another pretty common problem is that the old eSIM is still active and hasn't been properly cancelled out by the carrier system.

Coverage & Network Quality After Transfer

Once you've got that eSIM up and running on your new phone, the good news is that your network quality & signal strength remain exactly the same as before. The eSIM transfer process doesn't affect how well your phone connects to the network.

City dwellers tend to reconnect to LTE or 5G networks in a matter of seconds, while folks in the countryside may see a slight delay due to tower availability - but this is not down to the eSIM itself. After activation, just give your line a test by making a few calls and checking your mobile data to make sure everything is working as expected.

From a technical standpoint, an eSIM is just an identity card that lets your phone know who it is and how to connect to the right network. The quality of service you get is determined by your carrier's infrastructure, not how you've set up your phone.

eSIM vs Physical SIM vs Roaming

One of the things that prevents people from switching to an eSIM when upgrading a phone is that it can be a bit confusing & hasn't got the same flexibility as a physical SIM you can just swap in & out, which can be a problem if you're a frequent traveller or need to use 2 phone numbers.

Roaming plans, on the other hand, are often expensive & don't give you much in the way of flexibility. eSIMs usually offer the best balance between convenience & cost, which is why they're starting to become the norm for international travel & dual-number setups. In fact, in many markets the iPhone 14 and newer models only come with an eSIM.

Troubleshooting eSIM Transfer Issues

If your eSIM won't activate properly on your new phone, try restarting both the phone & the device that's trying to transfer the eSIM. Sometimes this will just sort the problem out. Also, make sure you're connected to Wi-Fi before trying to download the eSIM profile, as it's delivered digitally.

If the problem persists, make sure you're running the latest OS on both phones - older versions might not be able to support the newer eSIM transfer methods. In most cases, the easiest thing to do is get a new QR-code from your carrier or eSIM provider, which will reset the whole activation process. If you're having trouble getting your eSIM to transfer, or if either phone is locked, then you'll need to get in touch with your carrier.

Does Deleting an eSIM Affect Your New Phone?

Deleting an eSIM will remove it from your old phone, but it won't cancel out your mobile number or service - the number will still be active on your carrier account.

However, once you've deleted the eSIM, you won't be able to just pop it back onto another phone. You'll need to get in touch with your carrier to get a new eSIM or to reissue the old one. That's why it's a good idea to make sure the new phone is up and running properly before getting rid of the old one.

Does an eSIM Give You a New Phone Number?

No, it doesn't. eSIMs don't give you a new phone number.

Your number is linked to your carrier account, not the way your SIM card works. You can keep your existing number, switch to a new one, or even port one from another provider depending on your plan.

SIM ↔ eSIM Conversion

You can, but it depends on who your carrier is.

Many modern carriers have made it possible to transfer a physical SIM to an eSIM straight from the phone & supporting apps, while a few also allow you to switch an eSIM to a physical SIM. The important thing is not so much which way the change is made, but whether your carrier will let you do it at all.

Device Compatibility Overview

Most smartphones these days are eSIM capable, but how well they play along with eSIMs can vary.

The new iPhone models, for instance, have full eSIM support & can even do the whole transfer automatically. In fact, many iPhone 14 models & newer don't even have a physical SIM tray. Google Pixel devices & Samsung Galaxy S20 models are also good at setting up & migrating eSIMs, although availability can depend on your carrier. On the other hand, some budget phones & older models might not be able to support eSIMs at all, which can be a problem if you want to transfer an eSIM.

FAQ

Can I transfer an eSIM to a new phone?

Yes, but only if your carrier supports the transfer or has a different activation method set up.

Why won't my eSIM transfer?

It's probably because your carrier has got some restrictions in place to prevent direct transfers, & some carriers also tie eSIMs to a particular device at any one time.How do you get the eSIM up and running on a new phone ? The usual way is to follow the instructions handed down by your carrier which often involves scanning a QR code or using the carrier's app after you've finished setting up your new device.

Can you move an eSIM from an iPhone over to an Android? 

Honestly not directly. You'll need to do a full eSIM activation from scratch, and in some cases you might even have to shell out for a brand new eSIM.
