The fastest way to move to a new iPhone is to use iCloud or your old phone directly

You have three main paths to move your data, apps, and settings to a new iPhone. The quickest is Quick Start, which lets your old phone send everything to the new one over WiFi while they sit next to each other — this takes 20 minutes to an hour depending on how much you have. The second is iCloud backup, which uploads your data to Apple's servers from your old phone, then downloads it to the new one — this works if your phones aren't in the same place, but takes longer. The third is a computer backup using Finder (Mac) or iTunes (Windows), which is useful if you don't trust cloud storage or have spotty internet.

All three methods move your photos, messages, contacts, calendar events, app data, and settings. None of them move your SIM card or phone number — that stays with your carrier. If you're switching from Android to iPhone, the process is different and requires the Move to iOS app, which we cover separately below.

Key Takeaways

  • Quick Start is the fastest method if both phones are in front of you — it transfers everything wirelessly in one session without needing a computer or iCloud account.
  • iCloud backup works when your phones are in different places, but you need enough free iCloud storage (often 50 GB or more) and a WiFi connection on both devices.
  • Computer backup via Finder or iTunes is the most reliable for large amounts of data and doesn't depend on cloud storage or WiFi strength.
  • Your phone number and SIM card do not transfer — you keep your existing number and SIM unless you're switching carriers.
  • If you're coming from Android, use the Move to iOS app instead of these methods, as it handles the different system architecture.

Using Quick Start to transfer between two iPhones

Quick Start is the easiest method if you have both phones. Turn on your new iPhone and place it next to your old one. Your old phone will detect the new one and ask if you want to set it up. Tap "Continue" on the old phone, then hold it above the new phone's camera so it can read the animation on the screen. This takes a few seconds.

Next, enter your Apple ID password on the new phone. Your old phone will then send your WiFi network name and password, your Apple ID settings, and your iCloud backup to the new phone. The new phone will download your apps, photos, messages, and other data from iCloud while you watch. Do not unplug either phone or move them far apart during this process. When it finishes, your new phone will look and work like your old one.

Quick Start works best when both phones have good WiFi and are fully charged. If the transfer stalls, restart both phones and try again. If your old phone is too damaged to turn on, use iCloud backup instead.

Using iCloud backup when phones aren't together

iCloud backup is useful when you don't have your old phone nearby or it's broken. On your old iPhone, go to Settings > [Your Name] > iCloud > iCloud Backup and tap "Back Up Now." This uploads your data to Apple's servers. The backup includes everything except photos in your Camera Roll (unless you use iCloud Photos), so turn on iCloud Photos first if you want those backed up too.

Check how much iCloud storage you're using: Settings > [Your Name] > iCloud > Manage Storage. Most people get 5 GB free, which is rarely enough. You may need to buy 50 GB ($0.99/month) or 200 GB ($2.99/month). Delete old backups of other devices if you have them, or delete large files you don't need.

When your new iPhone arrives, turn it on and follow the setup screens. When asked how you want to set up, choose "Restore from iCloud Backup." Sign in with your Apple ID, select your most recent backup, and let it download. This can take hours if you have a lot of data or slow internet. Your apps will install in the background after setup finishes.

Using Finder or iTunes to back up on a computer

Computer backup is the most reliable method for large libraries of photos or music, and it doesn't use iCloud storage. On a Mac with macOS Catalina or newer, plug your old iPhone into the computer with a USB cable. Open Finder, click your phone's name in the sidebar, and click "Back Up Now" under the General tab. On a Windows PC, plug in your phone, open iTunes, click the phone icon, and click "Back Up Now." The backup file stores on your computer's hard drive.

When your new iPhone is ready, plug it in and open Finder or iTunes again. Click "Restore Backup," choose your most recent backup file, and enter your Apple ID password. The computer will copy everything to your new phone. This takes 30 minutes to several hours depending on how much data you have.

Computer backup is also useful if you want to keep a local copy of your data separate from iCloud, or if you have unreliable internet. You can make a new backup before you sell or recycle your old phone, giving you a safety copy.

Transferring from Android to iPhone using Move to iOS

If you're switching from an Android phone, the three methods above won't work because Android and iOS store data differently. Instead, download the Move to iOS app from the Google Play Store on your Android phone. On your new iPhone, during setup, tap "Migrate Data from Android" when you see it. Your iPhone will show a code.

Open Move to iOS on your Android phone, tap "Continue," agree to the terms, and enter the code from your iPhone. The app will then transfer your contacts, calendar events, photos, videos, text messages, mail accounts, and free apps. Paid apps won't transfer — you'll need to download them from the App Store on your iPhone. The transfer happens over WiFi and can take 30 minutes or more.

Keep both phones plugged in and on the same WiFi network during the transfer. If it fails partway through, you can run Move to iOS again and it will pick up where it left off. After the transfer completes, you can recycle your Android phone.

What doesn't transfer and what you need to do manually

Your phone number and SIM card stay with your old phone until you move them. Contact your carrier (Verizon, AT&T, T-Mobile, etc.) and ask them to activate your new iPhone on your existing number. They'll either mail you a new SIM card or activate your phone remotely — this usually takes a few minutes to a few hours. If you're keeping the same carrier, you may not need a new SIM at all.

Some apps don't transfer because they're tied to your old phone's hardware or because the developer removed them from the App Store. You'll see a list of these apps during setup. Download them manually from the App Store if they're still available. Banking apps, two-factor authentication apps, and some games may ask you to log in again on your new phone for security reasons.

If you use a password manager, authenticator app, or VPN, log into those on your new phone right away. Some apps store login information locally rather than in the cloud, so they won't transfer automatically. Your voicemail greeting and custom ringtones also don't transfer — you'll need to re-record the greeting and re-download ringtones from the App Store.

Troubleshooting a stuck or failed transfer

If Quick Start stalls, restart both phones and try again. Make sure both are on the same WiFi network and have at least 50% battery. If one phone keeps disconnecting, move closer to your router or try a different WiFi network. If Quick Start fails repeatedly, switch to iCloud backup instead.

If iCloud backup is taking too long, check your internet speed and close other apps using WiFi. Backups can take hours on slow connections. If the backup keeps failing, check your iCloud storage — if you're out of space, the backup will stop. Delete old backups or buy more storage, then try again.

If a computer backup fails, make sure your USB cable works (try a different one if you have it), restart both the computer and phone, and try again. If you see an error code, search Apple's support site for that specific code. If your phone is damaged or won't turn on, you won't be able to back it up — in that case, you'll lose any data that wasn't already backed up to iCloud.

Frequently Asked Questions

Do I need an Apple ID to transfer to a new iPhone?

Yes. Quick Start, iCloud backup, and computer backup all require an Apple ID to restore your data. If you don't have one, create it on your old phone in Settings > [Your Name] > iCloud, or on Apple's website. You'll need a valid email address and a password.

Can I transfer my data if my old iPhone won't turn on?

If your old phone won't turn on, you can't use Quick Start or back it up yourself. If you previously backed up to iCloud, you can restore from that backup on your new phone. If you never backed up, that data is lost. This is why regular backups matter — turn on automatic iCloud backup in Settings > [Your Name] > iCloud > iCloud Backup to avoid this in the future.

How much storage do I need on my new iPhone?

Your new iPhone needs at least as much free storage as your backup file. If your backup is 64 GB, you need a phone with at least 128 GB of storage. Check your backup size before you buy: on your old phone, go to Settings > [Your Name] > iCloud > Manage Storage and look at the backup size listed under your device name.

Will my text messages transfer to the new iPhone?

Yes, all three transfer methods (Quick Start, iCloud backup, and computer backup) move your text messages, including iMessages and SMS. If you're switching from Android, Move to iOS will transfer SMS messages but not all iMessages, since Android doesn't use iMessage.

Can I transfer apps I paid for to my new iPhone?

Yes, if you bought them with the same Apple ID. They'll download automatically during the transfer. If you bought an app with a different Apple ID, you'll need to download it again on your new phone using that Apple ID, or buy it again with your current Apple ID.
