Ready to transfer to iOS? Download the Move to iOS app to get help switching from your Android device to your new iPhone, iPad, or iPod touch.
Download Move to iOS from Google Play
Here's what you need
iOS 9 or later
On your Android device, make sure that Wi-Fi is turned on.
Plug your new iOS device and your Android device into power.
Make sure that the content you're moving, including what's on your external Micro SD card, will fit on your new iOS device
If you want to transfer your Chrome bookmarks, update to the latest version of Chrome on your Android device.
Tap Move Data from Android
While you set up your new iOS device, look for the Apps & Data screen. Then tap Move Data from Android. (If you already finished setup, you need to erase your iOS device and start over. If you don't want to erase, just transfer your content manually.)
Open the Move to iOS app
On your Android device, open the Move to iOS app and tap Continue. Read the terms and conditions that appear. To continue, tap Agree, then tap Next in the top-right corner of the Find Your Code screen.
Wait for a code
On your iOS device, tap Continue on the screen called Move from Android. Then wait for a ten-digit or six-digit code to appear. If your Android device shows an alert that you have a weak Internet connection, you can ignore the alert.
Choose your content and wait
On your Android device, select the content that you want to transfer and tap Next. Then—even if your Android indicates that the process is complete—leave both devices alone until the loading bar that appears on your iOS device finishes. The whole transfer can take a while, depending on how much content you're moving.
Here's what gets transferred: contacts, message history, camera photos and videos, web bookmarks, mail accounts, and calendars. If they're available on both Google Play and the App Store, some of your free apps will also transfer.
Set up your iOS device
After the loading bar finishes on your iOS device, tap Done on your Android device. Then tap Continue on your iOS device and follow the onscreen steps to finish setup for your iOS device.
Make sure that all of your content transferred. If some of it didn't transfer, you can move that content manually.
