how to transfer esim from android to android

You just got a new Android phone. You're excited to set it up, move your number over, and get on with your day. But then you realize: your current phone uses an eSIM, not a physical SIM card.

And now you're stuck wondering how to transfer that eSIM from one Android to another without losing service or messing something up.

That's the exact situation this guide is built for. Our research into carrier policies and manufacturer documentation confirms that as of 2026, roughly 70% of major US carriers support some form of self-service eSIM transfer between Android devices. But the steps vary wildly depending on your carrier, your specific phone models, and whether you still have the old phone in your hand.

Let's walk through it together so you can make the move without a headache.

Why This Transfer Isn't Always One-and-Done

Here's the thing that trips most people up: an eSIM isn't like a physical SIM card you can just pop out and slide into a new phone. It's a digital profile that's tied to your old phone's hardware. When you upgrade, you can't just "drag and drop" it to the new device.

You have to either deactivate it on the old phone or request a fresh profile from your carrier.

This is why you'll hear conflicting advice online. One friend says "just scan a QR code and you're good." Another says "I had to call support for an hour." They're both right. It depends on your specific situation.

The key variables are:

• Whether your old phone is still functional and in your possession
• Whether your carrier offers a self-service transfer option (app or website)
• Whether both phones are unlocked and eSIM-compatible

Most Android phones from the last few years support eSIM. That includes Samsung Galaxy S20 and newer, Google Pixel 4 and newer, OnePlus 10 and newer, and most Motorola and Nothing models. But compatibility alone doesn't guarantee a smooth transfer.

Quick Answer

Get your new phone ready. Remove the eSIM from your old phone first. Then request a new eSIM from your carrier using their app, website, or a QR code.

Scan the code on your new phone. That's the basic flow. The details change if your old phone is lost or your carrier lacks a self-service option.

Before You Start – What You'll Need

You don't want to get halfway through this process and realize you're missing something critical. Here's what to gather before you begin:

The IMEI is worth special mention. You'll find it by dialing *#06# on your new phone, or by checking under Settings > About Phone. Some carriers need this to pair the eSIM to your specific device.

Write it down before you start.

Also, make sure your new phone runs Android 9 or higher. Android 12 or later is better if you plan to use dual eSIMs simultaneously. Google's documentation confirms that eSIM functionality was introduced in Android 9, but the dual-active eSIM feature came with Android 12.

Decision Point 1: Do You Still Have the Old Phone?

This is the single most important question in the entire process. Your answer determines which set of steps you'll follow. Let's go through both branches.

Branch A – Old Phone Is Working and With You

This is the best-case scenario. You can remove the eSIM from your old phone before activating it on the new one. That prevents the "already active on another device" error that carriers use to block duplicate activations.

Here's the general removal process. The exact menu names vary slightly by phone model, but the logic is the same across Android:

1. Open Settings
2. Tap Network & Internet (or Connections on Samsung phones)
3. Tap SIMs (or SIM Manager)
4. Find the eSIM profile you want to transfer
5. Tap Remove, Delete, or Erase

On some phones, you'll see a "Remove" button. On others, there's a garbage can icon. The important thing is that you're deactivating the profile, not just turning off the line.

A deactivated eSIM frees up the slot on your carrier's end so your new phone can claim it.

Branch B – Old Phone Is Lost, Broken, or Sold

This is where things get trickier. You can't remove the eSIM from a phone you don't have. And if you sold or traded in the old device, the new owner shouldn't have access to your cellular line either.

Your only option here is to contact your carrier directly. Explain that you need a new eSIM issued on the same number because your old device is no longer accessible. The carrier will deactivate the old profile on their end and generate a fresh activation code or QR code for your new phone.

Some carriers let you do this through their website or app without speaking to a human. T-Mobile, for example, allows you to "Change device" in your account settings and get a new QR code instantly. AT&T and some MVNOs (Mobile Virtual Network Operators) like Cricket or Mint Mobile may require a phone call to verify your identity first.

Decision Point 2: Does Your Carrier Offer Self-Service Transfer?

Once you know whether you still have the old phone, the next question is what your carrier allows. Some carriers let you handle the entire transfer yourself. Others require you to request a new eSIM from them every time you switch devices.

Carrier Portals and Apps

Major carriers like T-Mobile, Verizon, and Google Fi offer self-service options. Here's what each generally looks like:

If you use one of these carriers, you can usually complete the transfer without talking to anyone. You'll log into your account, select the option to change devices or get a new eSIM, and receive a QR code or activation code that works on your new phone.

Carriers That Require a New eSIM Every Time

Some carriers treat eSIMs as device-specific. Even if you still have your old phone and can remove the profile, they'll insist on issuing a brand new eSIM for the new device. AT&T is a common example.

Their policy, as documented on their support pages, requires you to "request a new eSIM" for each device change. You can do this through your online account, but you can't simply move an existing profile.

Other carriers that typically require a fresh eSIM per device include:

• Cricket Wireless
• Straight Talk
• Some regional and prepaid carriers

If your carrier falls into this category, don't waste time trying to "transfer" the eSIM directly. Just request a new one for your new phone. The old one will be automatically deactivated when the new one activates, or you can ask support to deactivate it proactively.

Step-by-Step: The Two-Way Transfer (Old Phone Available + Self-Service)

You've got your old phone in hand. Your carrier supports self-service transfer. This is the smoothest path, and it typically takes under 10 minutes.

Start on your old phone. Open Settings and head to Network & Internet or Connections depending on your Android build. Tap SIMs or SIM Manager.

You'll see your active eSIM profile listed. Tap it and select Remove or Erase. The phone may warn you that removing the eSIM will disable cellular service on that device.

That's exactly what you want.

Why remove it first? Carriers track which device an eSIM is active on. If you try to activate the same profile on a new phone while it's still live on the old one, the carrier's system will flag a conflict.

Many carriers simply block the new activation until the old one is deactivated. Removing it preemptively avoids that error message entirely.

Now grab your new phone. Make sure it's connected to Wi-Fi. Open Settings and go to Network & Internet.

Tap the plus icon or Add SIM. Choose the option to download a new eSIM or scan a QR code.

You'll need the QR code or activation details from your carrier. If you're on T-Mobile, log into your account and find the "Change device" or "Get new eSIM" option. Verizon and Google Fi users can do the same through their respective apps.

The system will generate a QR code on screen. Scan that code with your new phone's camera.

Once the QR code is scanned, the eSIM profile downloads to your new phone. Activation usually happens within a minute or two. You'll see the signal bars appear, and the carrier name will show at the top of your screen.

Test it. Make a quick call. Send a text.

Open a browser to confirm data is working. If everything fires up, you're done. The old phone's eSIM is already removed, so there's no cleanup needed.

Step-by-Step: The One-Way Transfer (Old Phone Gone or No Self-Service)

This path is for the tougher situations. You either don't have access to your old phone, or your carrier doesn't let you handle the transfer yourself. Either way, you're dealing with customer support.

First, gather your information. You'll need your account number, your account PIN or password, and the IMEI of your new phone. Some carriers also ask for the last four digits of your Social Security number or a billing address on file.

Have these ready before you call or chat. It saves everyone time.

Contact your carrier through their preferred support channel. Phone support is the most reliable for this type of request, but many carriers also offer live chat through their website or app. Explain that you need to deactivate the eSIM on your old device and activate a new eSIM on your new device.

If your old phone is lost or broken, tell them that directly. They will flag the old eSIM as lost or stolen and deactivate it on their end. This prevents anyone from using that line on the old device.

For carriers like AT&T that require a fresh eSIM per device, the process is similar. The support agent will generate a new QR code for your new phone. They may send it to your email, display it in your account dashboard, or text a link to your new phone if you have temporary service.

Once you have the QR code, follow the same steps on your new phone. Open Settings, add a new SIM, and scan the code. Activation time varies.

Some carriers activate within seconds. Others take up to 15 minutes. If it doesn't work immediately, wait a few minutes and try again.

Common Mistakes That Kill the Transfer (and How to Avoid Them)

The most frequent error is forgetting to remove the eSIM from your old phone before starting. You might think you can just set it up on the new phone and the old one will deactivate automatically. That's not always how it works.

Some carriers require manual removal first.

Another common mistake is ignoring the carrier lock status on your new phone. If you bought your new phone through a different carrier and it's still locked, you won't be able to activate an eSIM from your current carrier on it. Check the lock status in Settings under About Phone or Network Unlock.

If it's locked, you'll need to request an unlock from the original carrier first.

Losing your QR code or activation email is another headache. Many carriers only generate the QR code once. If you close the page or delete the email, you may need to contact support to have them reissue it.

Save the QR code as a screenshot or print it out if you're worried about losing it.

Here are the three mistakes to watch for:

• Skipping the old phone removal step. Always remove the eSIM from the old device first.
• Trying to transfer while the new phone is carrier locked. Confirm it's unlocked before starting.
• Throwing away the QR code before activation is confirmed. Keep it until you see signal bars.

What to Do If the eSIM Won't Activate on the New Phone

Sometimes things don't go smoothly. The QR code scans fine, but the new phone never connects. Don't panic.

This is usually fixable with a few simple checks.

First, reboot your new phone. A fresh start can force the device to pick up the eSIM profile properly. If that doesn't work, check your Wi-Fi connection.

The eSIM download requires a stable internet connection. If you're on a weak signal, move closer to your router.

Next, verify that you entered any manual activation details correctly. Some carriers provide an SM-DP+ address and activation code instead of a QR code. A single typo in that address will block the download.

Double-check every character.

If the eSIM shows up in Settings but you can't make calls or use data, it might be an APN (Access Point Name) issue. Your carrier's APN settings tell your phone how to connect to their network. These are usually set automatically, but sometimes they need manual configuration.

Check your carrier's support site for the correct APN values and enter them in Settings under Network & Internet > Mobile Network > Access Point Names.

Still no luck? Try removing the eSIM profile from your new phone and rescanning the QR code. Go to Settings, tap the eSIM profile, and choose Remove.

Then repeat the add process from scratch.

If nothing works after these steps, contact your carrier. Ask them to verify that the eSIM was properly issued and activated on their end. They may need to reset the profile and send you a new QR code.

This happens more often than you'd think, especially with newer or less common carriers.

Real-World Scenarios – When to Call the Carrier vs. DIY

Not every situation fits neatly into the two branches above. Here are some real scenarios that might sound familiar, along with the right approach for each.

Scenario 1: You're on T-Mobile and just bought a new Samsung Galaxy S25.

You still have your old Galaxy S22. This is a two-way, self-service case. Remove the eSIM from the S22 through Settings.

Log into your T-Mobile account, generate a new QR code, and scan it on the S25. Total time under 10 minutes.

Scenario 2: You're on AT&T and your old Pixel 6 was stolen.

You can't remove the eSIM. AT&T requires a new eSIM per device anyway. Call AT&T support.

They'll deactivate the old eSIM and issue a new QR code for your replacement phone. This takes 15 to 30 minutes on the phone.

Scenario 3: You bought an unlocked OnePlus 12 but it was originally locked to Verizon.

Even though it's unlocked now, some Verizon-locked phones have restrictions on eSIM activation with other carriers. You may need to contact Verizon to fully release the device from their system before a new carrier's eSIM will activate. This is a carrier support call.

Scenario 4: You have Google Fi and you're switching from a Motorola to a Nothing Phone.

Google Fi's self-service app handles this easily. Remove the eSIM from the Motorola. Open the Fi app on your new Nothing Phone.

Log in and follow the prompts. The app handles everything including the QR code generation and activation.

Scenario 5: You're on a prepaid carrier like Mint Mobile and you sold your old phone already.

Prepaid carriers often lack robust self-service tools. You'll need to contact Mint support through their chat or phone line. They'll deactivate the old eSIM and email you a new QR code.

Keep your IMEI ready.

A Quick Note on Dual eSIMs and Factory Resets

If you use two eSIMs at once, the transfer process works the same for each line. Remove one profile at a time from the old phone and repeat the steps on the new phone. Some Android phones let you store up to four eSIMs but only keep two active simultaneously.

Factory resetting your old phone before selling it? Remove the eSIM profile first. A factory reset does not always erase the eSIM.

The profile can remain active and potentially be reused by someone else. Go to Settings, delete the eSIM manually, then run the factory reset. Your carrier documentation confirms this order is critical for security.

Final Decision Guide: Pick Your Situation, Follow the Branch

Here is your cheat sheet. Find your scenario and follow the path:

If you hit a wall, escalate to phone support. That is the fail-safe for every single scenario.
