First: Which Kind of eSIM Are You Moving?
This is the question that determines everything, and most guides skip it. There are two very different kinds of eSIM on your phone, and they transfer very differently:
Carrier eSIM (your main number)
Verizon, AT&T, T-Mobile, EE, etc. These transfer easily — Apple and Google both have built-in device-to-device transfer tools, and your carrier can always reissue the eSIM if the tools fail.
Travel eSIM (prepaid data plan)
Airalo, Saily, Nomad, Holafly, etc. These are usually single-install — the profile can't be moved with the built-in transfer tools. More on your options below.
Golden Rule: Don't Wipe the Old Phone Yet
Whatever method you use, keep your old phone intact and powered on until the new phone has working service. Device-to-device transfers need the old phone to confirm the handoff, and if anything goes wrong, your carrier can recover the line far more easily while the old device still exists. Factory-reset the old phone last, not first.
phone_iphoneiPhone → iPhone
Requirements: iOS 16+ on both devices, carrier must support eSIM Quick Transfer
Apple's eSIM Quick Transfer is the smoothest transfer experience of any platform. There are two ways to do it:
During setup (easiest): When setting up the new iPhone with Quick Start, look for the Transfer eSIM / Set Up Cellular screen and choose to transfer your number
After setup: On the new iPhone, open Settings → Cellular → Add eSIM
Tap Transfer From Nearby iPhone (both phones unlocked, Bluetooth on, same Apple ID)
On your old iPhone, tap the confirmation prompt and follow the instructions
Wait for the transfer — the line activates on the new iPhone and deactivates on the old one
Test a call or load a page with WiFi off to confirm the new phone has service
Tip: US iPhone 14 and later have no physical SIM tray, so if you're upgrading from an older iPhone with a physical SIM, the same setup flow converts it to eSIM automatically.
smartphoneAndroid → Android
Requirements: Android 14+ (Pixel), One UI 5.1+ (Samsung) — carrier support varies
Android's eSIM transfer tools are newer and carrier support is patchier than Apple's — if the option doesn't appear, fall back to your carrier's app.
Pixel: During new-phone setup, choose to transfer your SIM when prompted — or go to Settings → Network & internet → SIMs → Add SIM and look for the transfer option
Samsung: Open Settings → Connections → SIM manager → Add eSIM → Transfer SIM from another device
Confirm the transfer on your old phone when prompted
Wait for the eSIM profile to download and activate on the new phone
If no transfer option appears, your carrier doesn't support device-to-device transfer — use their app or support chat to request a new eSIM activation
Test the new phone's connection before wiping the old one
Tip: Samsung's transfer tool is Samsung-to-Samsung only, and Google's works best Pixel-to-Pixel. Mixed-brand Android transfers usually mean going through your carrier.
sync_altiPhone ↔ Android
Requirements: Any devices — goes through your carrier
There's no direct transfer between platforms. Your carrier deactivates the old eSIM and issues a fresh one for the new phone:
Open your carrier's app on the new phone (or their website/support chat)
Request an eSIM transfer or replacement for your line
Verify your identity — most carriers require account credentials or a one-time code
Scan the QR code they issue, or accept the eSIM push notification
Wait for activation, then confirm the old device shows No Service
Delete the dead eSIM profile from the old phone
Tip: Major US carriers (Verizon, AT&T, T-Mobile) all handle this free through their apps in under 10 minutes. Prepaid and MVNO carriers may require a support chat instead.
travelTravel eSIMs: The Exception
Travel eSIM profiles from providers like Airalo, Saily, Nomad, and Holafly are provisioned for a single installation. The iPhone and Android transfer tools won't move them, and re-scanning your original QR code on the new phone typically fails because the profile has already been consumed.
Your realistic options:
Plan expired or data used up?
Nothing to transfer — just delete the old profile and buy your next plan on the new phone.
Active plan with data left?
Contact the provider's support (in-app chat is fastest) before wiping your old phone. Some will reissue the eSIM to your new device — it's case-by-case, not guaranteed, and policies change, so ask first.
Upgrading soon and traveling soon?
Sequence it: either finish your current plan before switching phones, or switch phones first and buy the travel eSIM on the new device. Avoid switching mid-plan.
One quiet upside: because travel eSIMs are cheap and prepaid, "losing" one is rarely a disaster. A replacement plan for most destinations costs less than a hotel breakfast — compare current prices for your destination and treat the new phone as a fresh start.
Troubleshooting Transfer Problems
"Transfer From Nearby iPhone" never appears
Check both phones are on iOS 16+, Bluetooth is on, both are unlocked, and both use the same Apple ID. If it still doesn't show, your carrier doesn't support Quick Transfer — use their app to request a new eSIM instead.
Transfer completed but new phone shows No Service
Toggle Airplane Mode on/off, then restart the phone. Check the eSIM line is turned on and set as your data line (Settings → Cellular on iPhone, SIM manager on Samsung). Activation can also lag a few minutes on the carrier side.
Old phone still shows service after transfer
Give it a few minutes — deactivation isn't always instant. If both phones claim to have the line active after a restart, contact your carrier to confirm which device holds it.
Carrier QR code says it's already been used
eSIM QR codes are one-time use. Ask your carrier (or travel eSIM provider) to generate a fresh activation code — never reuse an old screenshot of a QR code.
New phone, new trip coming up?
Compare travel eSIM plans from 15+ providers and start fresh on your new device — most install in under 5 minutes.
