Getting a new phone is exciting, but moving your eSIM can seem confusing if you've never done it before. Unlike a physical SIM card that you simply remove and insert into another device, an eSIM is stored digitally inside your phone and must be transferred using your carrier's activation process.
The good news is that most eSIM transfers only take a few minutes. Many carriers now support automatic transfers between compatible devices, while others simply require you to scan a new QR code or use their mobile app.
This guide explains how to transfer an eSIM to a new phone on both iPhone and Android, what to do if the transfer fails, and how to avoid losing your mobile service during the process.
Before You Transfer Your eSIM
Before starting, make sure you:
- Keep your old phone switched on.
- Connect both phones to a stable Wi-Fi network.
- Update both devices to the latest software version.
- Make sure your carrier supports eSIM transfers.
- Back up your important data before setting up the new phone.
Tip: Don't erase or factory reset your old phone until your eSIM is fully working on the new device.
Can You Transfer an eSIM to Another Phone?
Yes—but unlike a physical SIM card, an eSIM can only be active on one device at a time.
When you transfer your eSIM, your carrier deactivates it on the old phone and activates it on the new one. The exact process depends on your carrier and phone model.
Some carriers support automatic transfers, while others require a new activation QR code or activation through their app or website.
Method 1: Transfer an eSIM from iPhone to iPhone
Apple makes transferring an eSIM very simple on supported carriers.
Step 1: Prepare Both iPhones
- Place both phones next to each other.
- Connect both to Wi-Fi.
- Turn Bluetooth on.
- Sign in with the same Apple ID if you're setting up the new phone.
Step 2: Transfer the eSIM
- Open Settings > Cellular on the new iPhone.
- Tap Add eSIM.
- Choose Transfer From Nearby iPhone (if available).
- Approve the request on your old iPhone.
- Wait for activation to complete.
The transfer usually finishes within a few minutes.

Method 2: Transfer an eSIM Between Android Phones
Many newer Android devices—including recent Google Pixel and Samsung Galaxy models—support eSIM transfers. The exact steps may vary depending on your phone manufacturer and mobile carrier.
Step 1: Set Up Your New Phone
- Turn on the new device.
- Connect to Wi-Fi.
- Follow the setup wizard.
Step 2: Transfer the eSIM
If your device supports it:
- Open Settings > Network & Internet > SIMs (or similar).
- Choose Add eSIM.
- Select the option to transfer your existing eSIM if available.
- Follow the on-screen instructions.
- Confirm the transfer on your old phone if prompted.
Some Android phones instead ask you to scan a QR code generated during setup.
If your phone doesn't offer a transfer option, use the manual method below.
Method 3: Transfer an eSIM Using Your Carrier
If you're moving between iPhone and Android—or your carrier doesn't support automatic transfers—you'll usually need to activate a new eSIM profile.
Step 1: Sign In to Your Carrier Account
Use your carrier's website or official mobile app.
Look for options such as:
- Replace eSIM
- Transfer eSIM
- Activate New Device
- SIM Management
Step 2: Verify Your Identity
Depending on your carrier, you may receive verification through:
- SMS
- Authentication app
- Carrier mobile app
Step 3: Activate Your New Phone
Your carrier will usually provide:
- a QR code
- an activation code
- or automatic activation through their app.
Scan the QR code or follow your carrier's instructions to finish activation.
Only remove the old eSIM after your new phone successfully connects to the network.
What If Your Old Phone Is Lost or Broken?
You can still transfer your number.
Most carriers allow you to generate a replacement eSIM through your online account or by contacting customer support.
You may need to verify your identity before a new activation code is issued.
eSIM Transfer Not Working?
If your eSIM won't activate, try these fixes before contacting your carrier.
Restart Both Phones
A simple restart often completes pending network registration.
Check Your Internet Connection
An eSIM cannot download without a working Wi-Fi or mobile data connection.
Install Software Updates
Older versions of iOS or Android can sometimes cause activation problems.
Request a New QR Code
Many carriers only allow a QR code to be scanned once.
If you've already used it, request a replacement.
Contact Your Carrier
If activation still fails, your carrier can reset your eSIM profile and issue a fresh activation.

Conclusion
Transferring an eSIM to a new phone is much easier than it was a few years ago. Many iPhones and newer Android devices now support direct transfers, while most carriers offer simple online activation if automatic migration isn't available.
The key is to keep your old phone active until the new one connects successfully. If you run into problems, requesting a new eSIM profile from your carrier usually resolves the issue quickly.
