To transfer data from an old iPhone to an iPhone 18 Pro or iPhone 18 Pro Max, use Quick Start with both phones nearby, Wi-Fi and Bluetooth on, and both devices connected to power.
If the transfer repeatedly fails, try a direct cable connection or restore an iCloud or computer backup. Cellular activation is a separate step: U.S. models are eSIM-only, while UK, German and French models accept nano-SIM and eSIM.
Keep the old phone until calls, photos, banking apps, authenticator codes and messages work on the new one.
Before You Transfer to iPhone 18 Pro
A short setup check can save a second attempt later.
- Update and back up: Update your old iPhone to its latest compatible iOS version. Make a fresh iCloud or encrypted Mac/PC backup, even if you plan a direct transfer.
- Keep sign-ins available: Know your Apple Account password and old phone passcode. Check how your banking and authenticator apps move to a new device.
- Check your number: Find out whether your new model has a SIM tray and whether your carrier supports eSIM Quick Transfer. Keep access to carrier verification messages.
-
Set aside time and power: Keep both phones charging and within reach. A direct migration occupies both devices until it finishes.
If you are not sure which backup method to use, follow our step-by-step guide to backing up your iPhone before an iOS update. The same backup process is useful before moving to an iPhone 18 Pro or iPhone 18 Pro Max.
Which iPhone 18 Pro Data Transfer Method Should You Choose?
Quick Start: easiest with both phones
Choose Transfer from iPhone during setup to move data directly. Both devices stay unavailable until the transfer finishes.
Wired transfer: useful for large libraries or unreliable wireless transfer
Connect an iPhone 15 or newer with a USB-C to USB-C cable. Moving from an iPhone 14 or earlier requires a USB-C to Lightning cable. Follow the setup prompts on both phones. A cable does not guarantee a particular speed.
iCloud restore: useful when you need the old phone back sooner
Choose an iCloud backup during setup; apps and data can continue downloading after you reach the Home Screen. A computer backup is another fallback. If you lack iCloud space, eligible new-device buyers can create a temporary backup from Settings → General → Transfer or Reset iPhone → Get Started.
Apple gives you 21 days to restore an eligible temporary iCloud backup. If delivery is delayed, Apple explains how to request more time. See Apple’s temporary storage instructions.
How to Use Quick Start on iPhone 18 Pro
- Unlock your old iPhone, connect it to Wi-Fi and turn on Bluetooth.
- Turn on the new iPhone 18 Pro and place it next to the old one.
- Follow the Quick Start prompt and scan the animation when asked.
- Connect the new phone to Wi-Fi or cellular, then set up Face ID.
- Choose Transfer from iPhone for a direct transfer, or select an iCloud backup.
- Leave both phones close together and plugged in until the process finishes.
If the setup prompt disappears, Apple advises restarting both devices. See Apple’s Quick Start guide.
How Does iPhone 18 Pro eSIM Transfer Work in the U.S. and Europe?
U.S. models are eSIM only. The iPhone 18 Pro and Pro Max have no physical SIM tray. If your old number is on a physical SIM, ask your carrier whether it supports conversion during setup. You may need eSIM Quick Transfer, carrier activation, an app or a QR code.
UK, German and French models support nano-SIM plus eSIM. You can move a compatible physical SIM or arrange an eSIM transfer through your carrier. Check the actual device if you bought an import model.
Apple’s eSIM Quick Transfer depends on carrier support. Once the number activates on your new iPhone, that plan stops working on the old SIM. If setup ends with SOS or No Service, open Settings → Cellular → Add eSIM and follow your carrier’s instructions. See our iPhone 18 Pro eSIM activation guide.
Why Is iPhone 18 Pro Quick Start Stuck or Taking So Long?
Apple gives no fixed transfer time: the amount of data and network conditions both matter. Diagnose the screen you actually see before starting over.
“Preparing to Transfer” or a changing estimate
Keep both devices near each other and on power. Large photo and video libraries can take longer. An estimate that changes is not, by itself, proof of a failed transfer.
“Looking for Nearby Devices”
Unlock the old phone and check Wi-Fi, Bluetooth and distance. Restart both if the Quick Start prompt disappears.
Software update during setup
Give the update time to finish with power connected. If an update repeatedly interrupts setup, use Apple’s setup support before repeatedly resetting a phone that holds your only copy of data.
Transfer repeatedly fails
After checking the backup, try Apple’s wired transfer steps or restore from iCloud or a computer. See our Quick Start troubleshooting guide for more specific fixes.
ZEERA observation: After reviewing Apple’s migration steps, the most consequential avoidable mistake is handing in the old iPhone before verifying the new one can receive calls and authentication codes.
What Should You Check Before Erasing Your Old iPhone?
Seeing the Home Screen is only the first checkpoint. With iCloud restore, some downloads continue in the background.
- Calls and data: Place a call and turn off Wi-Fi briefly to test cellular data. Test SMS if you use it for verification.
- Photos and conversations: Open older photos, contacts, Notes and key message threads. Check WhatsApp or Signal if you use them.
- Payments and account access: Open banking apps, verify cards in Wallet and generate a code from each important authenticator.
- Apple Watch: Confirm it is paired with the new iPhone. Check essential car and Bluetooth connections too.
When these checks pass and your backup is confirmed, erase the trade-in phone at Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. Follow the onscreen Apple Account and eSIM prompts carefully, then confirm the trade-in requirements.
Are iPhone Ultra Setup and Accessory Searches About iPhone Duo?
If you searched for iPhone Ultra transfer data, the foldable phone that circulated under that name is sold as iPhone Duo. The same Apple migration choices apply, but search for an iPhone Duo case designed for its foldable body rather than an iPhone 18 Pro case. Confirm charging and MagSafe accessory compatibility against the actual product listing.
Frequently Asked Questions
How long does an iPhone 18 Pro data transfer take?
There is no universal estimate. Data volume, connection and network conditions all affect the time; iCloud apps may continue downloading after setup.
Is wired transfer always faster than wireless Quick Start?
No fixed speed advantage is guaranteed. It is useful when wireless transfer is unstable or you have a large local library.
Can I move a physical SIM to a U.S. iPhone 18 Pro?
You cannot insert it: U.S. models use eSIM only. Ask your carrier how to convert or activate your number.
Does Apple offer free temporary iCloud storage for a new iPhone?
Eligible buyers who lack space for a migration backup can get temporary storage. Restore that backup within 21 days, or use Apple’s extension option if delivery is delayed.
Can I erase my old iPhone as soon as Quick Start finishes?
Wait until cellular, messages, photos, banking, Wallet and two-factor sign-ins are verified on the new phone.
