What happens when you move your eSIM to a new phone
An eSIM is a digital version of a SIM card that lives in your phone's software instead of as a physical chip. When you get a new phone, you don't move the eSIM itself — instead, you download your carrier's profile onto the new device. The process is different depending on whether your old phone and new phone are the same brand, and whether you're switching carriers or staying with the same one.
Most carriers let you transfer an eSIM without calling them, though some require a quick phone call or online request. The whole process usually takes 15 minutes to an hour. Your old phone will lose service once the transfer completes, so plan to do this when you're ready to fully switch.
Key Takeaways
- You download your eSIM profile to your new phone rather than physically moving anything, and the process differs slightly by carrier.
- Before you start, write down your carrier name, phone number, and account PIN if you have one — you'll need these to verify your identity.
- Most carriers let you transfer through their website or app, but some require a phone call or in-person visit to a store.
- Your old phone loses service the moment the transfer completes, so make sure your new phone is set up and working before you finish.
Gather your account information before you start
Before you touch either phone, collect the details your carrier will ask for. You need your phone number, the email address or username associated with your account, and your account PIN if you set one up. If you don't know your PIN, most carriers can send a temporary one to your email or phone number.
Write these down or take a screenshot — you'll reference them during the transfer. If you're switching from an iPhone to an Android phone or vice versa, the steps are slightly different, so know which devices you're moving between. Check your carrier's website to see whether they handle eSIM transfers online, through their app, or by phone.
Transfer through your carrier's website or app
Most major carriers (Verizon, AT&T, T-Mobile, and most regional carriers) let you start the transfer from your computer or through their mobile app. Log into your account on the carrier's website, look for a section called "Manage eSIM," "Transfer eSIM," or "Activate a new device," and select your phone number.
The carrier will ask you to confirm your identity — usually by entering your PIN, answering security questions, or confirming a code sent to your email. Once you're verified, the carrier generates a QR code or confirmation code. On your new phone, go to Settings, find the Cellular or Mobile Network section, and choose "Add Cellular Plan" or "Activate eSIM." Scan the QR code with your new phone's camera, or enter the confirmation code manually if that's an option.
Your new phone will download the eSIM profile within a few minutes. You'll see a message saying the plan is active. At this point, your old phone will lose service — this is normal and expected. If your new phone doesn't show service after 10 minutes, restart it and check Settings again.
Transfer by phone call if your carrier requires it
Some carriers, particularly smaller regional ones, don't offer online eSIM transfers. Call your carrier's customer service number (on your bill or their website) and tell them you're moving your eSIM to a new phone. Have your account PIN, phone number, and the model of your new phone ready.
The representative will verify your identity and then either send you a QR code by email or text, or walk you through entering a code directly into your new phone. The process is the same as the online method once you have the code — scan it or type it into your new phone's Cellular settings. Ask the representative to confirm when the transfer is complete so you know your old phone should lose service.
What to do if the transfer fails or your new phone has no service
If your new phone doesn't show service 15 minutes after completing the transfer, restart the phone first. Go to Settings, turn Airplane Mode on for 10 seconds, then turn it off. This forces your phone to reconnect to the carrier's network.
If you still see no service, check that you're in an area with coverage for your carrier — use their coverage map on their website. If coverage is fine but service still isn't working, contact your carrier and tell them the transfer completed but your new phone isn't connecting. They can resend the eSIM profile or troubleshoot the activation on their end. Keep your old phone nearby during this call in case they need information from it.
If your old phone still has service after the transfer should have completed, the transfer didn't go through. Go back to your carrier's website or app and check the status. You may need to restart the old phone, wait a few minutes, and try the transfer again.
Moving an eSIM between iPhones or between Android phones
If both your old and new phones are iPhones, you have an extra option: you can use iCloud to transfer your eSIM during setup. When you set up your new iPhone, choose "Transfer from iPhone" and sign in with your Apple ID. During the setup process, you'll see an option to transfer your eSIM. This is faster than going through your carrier's website, though it only works if both phones are iPhones and you're signed into the same Apple ID.
If you're moving between two Android phones, you don't have a built-in transfer method — you'll need to go through your carrier's website, app, or phone line. The process is identical to what's described above. Some Android phones let you back up your eSIM settings to your Google Account, but this is carrier-dependent, so check with your carrier first.
Switching carriers while moving to a new phone
If you're changing carriers at the same time you're getting a new phone, the process is different. Your old carrier will deactivate your eSIM once you request it, and your new carrier will send you a new eSIM profile to download. Contact your new carrier and tell them you're bringing your phone number from another carrier — they'll walk you through porting your number and activating your new eSIM.
This usually takes 24 hours, though it can be faster. During this time, you may lose service briefly. Once your new carrier's eSIM is active on your new phone, your old carrier's service will stop working. If you need to keep your old phone active for any reason, tell your old carrier before you start the switch — they may be able to keep it on a different plan temporarily.
Frequently Asked Questions
Can I use my eSIM on two phones at the same time?
No. An eSIM can only be active on one phone at a time. Once you download it to your new phone, your old phone loses service. If you need to use both phones temporarily, contact your carrier about keeping your old phone on a separate plan or SIM card.
What if I don't have a QR code and my carrier won't send one?
Some carriers let you enter the eSIM details manually instead of scanning a QR code. Ask your carrier for the activation code, IMEI, or other details needed to activate manually. If they can't provide these, you may need to visit a store in person or call their support line for a different activation method.
Do I need to turn off my old phone before transferring the eSIM?
No, but it's a good idea to keep it nearby in case your carrier needs information from it during the transfer. Once the transfer completes, your old phone will automatically lose service, so turning it off won't affect anything.
Will I lose my text messages and photos when I transfer my eSIM?
No. Your eSIM only contains your carrier information — it doesn't store messages, photos, or apps. Those are backed up separately through iCloud, Google Drive, or your carrier's backup service. Transfer your eSIM and your data separately using your phone's normal backup method.
How long does an eSIM transfer usually take?
The download to your new phone takes a few minutes once you scan the QR code or enter the code. The whole process from logging into your carrier's website to having service on your new phone usually takes 15 to 30 minutes. If you're switching carriers, the port can take up to 24 hours.
