The basic process: what happens when you move an eSIM

An eSIM is a digital SIM card stored on your phone's chip rather than a physical card you can remove. To move it to another phone, you don't physically transfer anything — instead, you download a new copy of the same eSIM profile onto the new device. Your carrier deactivates the profile on the old phone and activates it on the new one.

The exact steps depend on your carrier and which phone you're moving to, but the general flow is the same: you'll need your carrier account details, a way to receive a confirmation code (usually by text or email), and access to both phones during the transfer. Most carriers let you do this through their app or website, though some require a phone call.

The process usually takes a few minutes to an hour. Your service will drop on the old phone once the new phone is activated, so plan the transfer for a time when you won't need immediate access to calls or texts.

Key Takeaways

  • You download the eSIM profile onto the new phone rather than physically moving anything, and your carrier deactivates it on the old device once the new one is active.
  • Most carriers let you start the transfer through their mobile app or website, though some still require a phone call to customer service.
  • You'll need your carrier account login, a confirmation method (text or email code), and both phones available during the transfer.
  • The transfer usually completes within an hour, and your old phone loses service once the new phone is activated.
  • Some carriers charge a small fee to transfer an eSIM, while others do it at no cost — check your carrier's policy before you start.

Transfer through your carrier's app or website

Most major carriers — including Verizon, AT&T, T-Mobile, and many regional providers — offer eSIM transfer through their mobile app or website. Log into your account, look for a section labeled "Manage SIM," "Switch Device," or "Transfer eSIM," and follow the prompts. You'll typically be asked to confirm your identity, choose the new phone model, and verify your contact information.

The carrier will then send you a QR code or an activation code. On your new phone, go to Settings, find the Cellular or Mobile Network section, and select "Add Cellular Plan" or "Add eSIM." Scan the QR code with your camera, or enter the activation code manually. The new phone will download the profile, and your service should activate within a few minutes.

During this time, keep both phones powered on and connected to Wi-Fi if possible — a strong internet connection speeds up the download. Once the new phone shows active service, the old phone's eSIM will stop working. You can then power off or reset the old phone.

Transfer by calling your carrier's customer service

If your carrier doesn't offer online transfer, or if you run into problems with the app or website method, call customer service. Have your account number, the phone number associated with the eSIM, and the model of your new phone ready. The representative will verify your identity and then initiate the transfer on their end.

They'll either send you a QR code by text or email, or they'll give you an activation code to enter manually on the new phone. Follow the same steps as the app method: go to Settings, add the cellular plan, and scan or enter the code. The representative may stay on the line to confirm the transfer went through, or they may ask you to call back once your new phone shows service.

This method usually takes longer than the app route — expect 15 to 30 minutes on the phone plus another 10 to 15 minutes for the download on the new device. Some carriers charge a transfer fee when you call, though many waive it if you're a long-standing customer.

What to do if the transfer fails or gets stuck

If the QR code won't scan or the activation code doesn't work, the most common cause is a weak internet connection on the new phone. Switch to a different Wi-Fi network, or move closer to your router. If you're using mobile data, make sure it's enabled in Settings — you may need data from another carrier or a friend's phone to complete the download.

If the new phone says "Invalid Code" or "Activation Failed," the code may have expired. Go back to your carrier's app or website and request a new one. Some carriers limit how many times you can request a code in a short period, so if you've tried several times, wait 15 to 30 minutes before trying again.

If the transfer appears to complete but your new phone still has no service after an hour, restart the phone and check Settings to confirm the eSIM profile is installed. If it's there but inactive, call your carrier — the profile may need to be manually activated on their backend. If the profile isn't showing up at all, the download may not have finished; try the transfer again from the beginning.

Transferring an eSIM between different phone brands

Moving an eSIM from an iPhone to an Android phone, or vice versa, works the same way as transferring between phones of the same brand. The eSIM profile itself is carrier-specific, not device-specific, so the brand doesn't matter. What matters is that both phones support eSIM — most modern iPhones (iPhone XS and newer) and many Android phones do, but older models may not.

Before you start, check your new phone's specs to confirm it has eSIM support. If it does, follow your carrier's standard transfer process. The only difference you might notice is in the Settings menu layout — iPhones use "Cellular" while Android phones typically use "Mobile Network" or "SIM Cards" — but the steps are otherwise identical.

If your new phone doesn't support eSIM, you'll need to contact your carrier about switching to a physical SIM card instead. This usually requires ordering a new card and waiting for it to arrive by mail, though some carriers can activate a physical SIM in-store.

Keeping your old phone's data when you move the eSIM

Transferring an eSIM only moves your phone service — it doesn't move your photos, contacts, apps, or other data. You'll need to back up and restore your data separately using your phone's built-in backup system. iPhones use iCloud, and Android phones typically use Google Account backup or Samsung Cloud (if you have a Samsung).

Before you transfer the eSIM, back up your old phone to the cloud. Then set up your new phone and restore from that backup. This way, your data and your service will both be ready when you're done. If you restore after the eSIM transfer, you won't lose any service — the eSIM will stay active while the data downloads.

If you're selling or giving away your old phone, make sure to sign out of your accounts (Apple ID, Google Account, Samsung Account) before handing it over. This prevents the new owner from accessing your data and ensures you can't accidentally use up your backup storage on a device you no longer own.

Fees and timing for eSIM transfers

Most carriers do not charge a fee to transfer an eSIM, especially if you're moving to a new phone you purchased from them. However, some carriers charge $10 to $25 if you're transferring to a phone from a different brand or a third-party retailer, or if you call customer service instead of using the app. Check your carrier's website or call before you start to confirm whether there's a fee.

The transfer itself usually completes within an hour, but timing can vary. If you're transferring during peak hours (evenings or weekends), the download may take longer. If you're switching carriers entirely — not just moving your eSIM to a new phone on the same carrier — the process is different and may take a full business day. For carrier switches, you'll typically need to contact your new carrier to port your number, which is a separate process from eSIM transfer.

Frequently Asked Questions

Can I use my old phone while the eSIM transfer is happening?

You can use it for Wi-Fi calling or messaging apps, but you won't have cellular service once the new phone is activated. The old phone's eSIM stops working as soon as the carrier switches the profile to the new device. If you need to stay reachable during the transfer, do it at a time when you can be near Wi-Fi, or transfer during a time when you don't need immediate access to calls or texts.

What if I want to keep the same eSIM on both phones?

You can't have the same eSIM profile active on two phones at the same time — the carrier only allows one active copy. However, some carriers let you temporarily keep the profile on your old phone while you set up the new one, then transfer it later. Contact your carrier to ask if they offer this option; it's sometimes called a "grace period" or "dual activation window."

Do I need to tell my carrier before I transfer my eSIM?

No, you don't need to notify them in advance if you're using the app or website method. If you're calling customer service, they'll handle everything during the call. The only time you need to contact your carrier beforehand is if you're switching carriers entirely, which requires porting your phone number — that's a different process from eSIM transfer.

Can I transfer an eSIM if I forgot my carrier account password?

You'll need to reset your password through your carrier's website or app before you can start the transfer. Look for a "Forgot Password" link on the login page. If you can't access your email or the recovery method on file, call customer service — they can verify your identity and help you regain access to your account.

What happens to my phone number when I transfer the eSIM?

Your phone number stays the same — it's tied to the eSIM profile, not to the physical phone. When you transfer the eSIM to your new phone, your number transfers with it. You'll be able to make and receive calls and texts on the new phone using the same number you had on the old one.
