• iPhone to iPhone is the fastest transfer — use eSIM Quick Transfer during setup, takes about 60 seconds, no network call required.
• Cross-platform transfers (iPhone to Android or Android to iPhone) require contacting your UK network for a new QR code — free, takes 15-30 minutes in total.
• eSIM is now standard on all iPhone 14, 15, 16 and 17 models sold in the UK, plus most current Samsung Galaxy and Google Pixel devices — your next phone will almost certainly use eSIM only.

How Do I Transfer an eSIM to a New Phone? Complete 2026 UK Guide

Got a new phone and need to move your number across? In 2026, eSIM has gone from “the new way” to “the only way” for most major networks and devices. Apple stopped including physical SIM trays on UK iPhones a couple of years ago, Samsung’s flagship Galaxy phones are pushing eSIM-first, and Google Pixel has been eSIM-friendly for years. If you’ve just bought a new phone, you’re almost certainly looking at an eSIM transfer.

Good news: eSIM transfers are usually faster, easier and more reliable than the old “wait three days for the new SIM to arrive in the post” routine. Bad news: the process varies depending on what you’re moving from and to, and a few specific scenarios (like iPhone to Android) catch people out. This guide covers every common transfer scenario, with realistic UK timeframes from a 12-year phone repair specialist who helps customers do this every week.

What is an eSIM and Why Does It Matter?

An eSIM (embedded SIM) is a small chip permanently built into your phone that replaces the traditional plastic SIM card you used to slide into a tray. Instead of physically swapping cards between phones, you transfer the eSIM digitally — either using built-in transfer tools or by scanning a QR code from your network.

The benefits are genuine. eSIMs can’t be lost or damaged. Your phone is more water-resistant without a SIM tray. You can have multiple eSIMs active on one phone (handy for travel or work/personal split). And transfers between iPhones happen in seconds.

The downside is that the process is less standardised than physical SIMs were. Different networks handle it differently. Different phone brands have different transfer flows. And if anything goes wrong, you can’t just take the SIM out and pop it back into your old phone.

Quick Reference: Transfer Method by Scenario

How to Transfer an eSIM From iPhone to Another iPhone

This is the easiest scenario, and Apple has made it genuinely smooth. The eSIM Quick Transfer feature is built into iOS and works automatically during new iPhone setup.

Method 1: During New iPhone Setup (Easiest)

1. Set up your new iPhone using Quick Start with your old iPhone nearby (within Bluetooth range).
2. When the setup process reaches the cellular setup step, choose Transfer From Nearby iPhone.
3. Confirm on both devices when prompted.
4. The transfer completes in about 60 seconds. Your eSIM is automatically deactivated on the old iPhone.

Method 2: After Setup is Complete

If you’ve already set up your new iPhone without transferring the eSIM:

1. On the new iPhone, go to Settings > Cellular > Add eSIM.
2. Choose Transfer From Another iPhone.
3. Bring your old iPhone close. A prompt appears on the old iPhone — tap Transfer.
4. Confirm with the verification code sent to the old iPhone.
5. Transfer completes in about a minute.

Both iPhones need to be on iOS 16 or later for Quick Transfer to work properly. If you’re moving from a much older iPhone (iPhone 11 or earlier), the old iPhone may need to be updated first.

How to Transfer an eSIM From iPhone to Android (or Android to iPhone)

This is where most people get stuck, because Apple’s Quick Transfer doesn’t work cross-platform. The good news is the process is straightforward — it just requires contacting your network.

The Standard Process

1. Contact your UK network provider. Most networks now have eSIM transfer self-service in their app, but if not, a phone call or live chat works fine. Tell them you’ve got a new phone and need to transfer your eSIM.
2. The network deactivates your old eSIM. Your old phone loses signal — that’s normal. The number is still yours, just temporarily unrouted.
3. The network sends you a QR code by email or SMS (you’ll receive the SMS on a backup device, or by email).
4. Scan the QR code on your new phone. On iPhone: Settings > Cellular > Add eSIM > Use QR Code. On Samsung: Settings > Connections > SIM Manager > Add Mobile Plan. On Google Pixel: Settings > Network & Internet > SIMs > Add eSIM.
5. Activation completes in 1-5 minutes and your number is now on the new phone.

Network-Specific Notes

EE — handles eSIM transfers via the EE app or by calling 150 from a working phone. QR codes typically arrive within 10 minutes. Free.

O2 — eSIM transfers via the My O2 app or by calling 202. Same-day service during business hours. Free.

Vodafone — supports self-service eSIM transfer in the My Vodafone app. Calling 191 works too. Free.

Three — handles via the Three app or by calling 333. Free.

Giffgaff, Tesco Mobile, Sky Mobile, iD Mobile, Lebara — all support eSIM transfer free of charge, usually via app or live chat. Some MVNOs may take slightly longer (up to a few hours) than the major networks.

How to Transfer an eSIM Back to a Physical SIM

Sometimes you genuinely need a physical SIM — maybe you’re getting an older phone, or travelling somewhere that handles physical SIMs more easily, or your new device doesn’t support eSIM.

1. Contact your network and request a physical SIM swap.
2. The network posts you a physical SIM, usually within 2-5 working days in the UK.
3. When it arrives, follow the activation instructions (usually a text message or short code).
4. Your number, contract and billing stay exactly the same.

Most major UK networks do this for free. Some smaller MVNOs charge £5-£10 for the new physical SIM. Worth confirming the cost before requesting if you’re on a budget MVNO.

Common eSIM Transfer Problems and How to Fix Them

The Transfer Stalls Halfway Through

Usually a connection issue. Make sure both phones are connected to Wi-Fi (not just mobile data) and try again. If it still fails, restart both phones and retry.

“This eSIM is Already Active on Another Device”

Means the network hasn’t fully deactivated the old eSIM. Contact the network and ask them to manually clear the old activation. Usually fixed within 15 minutes.

QR Code Won’t Scan

Make sure the camera is focused properly and there’s good lighting. If the QR code is on the same phone you’re trying to activate (e.g. emailed to the new iPhone), use the manual activation code option instead — most networks include it alongside the QR code.

Lost Signal After Transfer

Toggle Airplane Mode on and off, or restart the phone. If signal doesn’t come back within 5 minutes, contact your network — they can usually push a refresh from their end.

Stuck on “Activating eSIM”

Some networks take up to 15 minutes to fully provision a new eSIM. If you’re past that window, restart the phone. If still stuck, contact the network.

What to Do if You’re Stuck

Most eSIM transfers go smoothly, but when they don’t, you can be left with a phone that won’t connect for hours. If you’re stuck mid-transfer and your network’s support line isn’t helping, you’ve got a few options:

• Check your network’s app — there’s often a self-service eSIM management section that resolves things faster than the call centre.
• Try a network store in person — if you’re near a major town with EE, O2, Vodafone or Three stores, they can usually fix eSIM issues at the counter.
• Get help locally — at Mend My iPhone in Market Weighton, we help East Yorkshire customers with eSIM transfers regularly. If you’re stuck and need someone to walk you through it (or do it for you), give us a call on 07934 062949. We’re local — Apple Stores are an hour away in Leeds.

Will My New Phone Even Have a Physical SIM Slot?

Probably not, especially if it’s a recent iPhone. As of 2026:

• iPhone 14, 15, 16, 17 series (UK) — eSIM only on most current models. No physical SIM tray.
• Samsung Galaxy S24, S25 series — both eSIM and physical SIM available; eSIM increasingly default.
• Google Pixel 8, 9, 10 — supports both eSIM and physical SIM.
• Older iPhones (iPhone 13 and below) — physical SIM tray still present.
• Budget Android phones — most still support physical SIM, often dual-SIM.

If you’re moving from an older iPhone with a physical SIM to a new iPhone, you’ll be making the eSIM transition for the first time. Don’t panic — it’s genuinely easier than the old method, just different.

Summary: Which Method Should I Use?

The fastest path:

• Both devices are iPhones? Use eSIM Quick Transfer during new iPhone setup. Done in a minute.
• Both devices are Samsung or both are Pixel? Use the brand’s built-in transfer tool.
• Different brands or platforms? Contact your network for a QR code. Free, fast, the same process whichever direction you’re going.
• Need a physical SIM? Contact your network and wait 2-5 working days for it to arrive in the post.
