How can I do for changing Iphone ?
Regarding a replacement of one Iphone, you don’t forget to save your old device.
Before you begin
- If you have an Apple Watch and you’re about to move content to a new iPhone, you need to unpair your watch from your current iPhone first. Unpairing automatically backs up your Apple Watch. Now you’re ready to set up your new iPhone. After that, you’ll pair your Apple Watch with your new iPhone.
- To move content to a new iOS device, you need an iCloud or iTunes backup of your current iOS device. If you aren’t sure whether to use iCloud or iTunes, learn about both to decide which method is best for you.
Back up your current device using iCloud. Then you can transfer the backup to your new device.
Make an iCloud backup
- Connect your old device to the Internet with Wi-Fi.
- In iOS 8 or later, tap Settings > iCloud > Backup. In iOS 7 or earlier, tap Settings > iCloud > Storage & Backup.
- Make sure that iCloud Backup is turned on.
- Tap Back Up Now. Stay connected to Wi-Fi until the process finishes.
- Make sure the backup finished in Settings > iCloud > Storage > Manage Storage. It should appear with the correct date and size.
Transfer your SIM card or contact your carrier
Here’s what to do if your current device has a SIM card:
- If your carrier gave you a new SIM card, put it in your new device.
- If your new device uses the same kind of SIM card as your current device, transfer the SIM to your new device.
- If your new device needs a different kind of SIM card than what you have, or if you aren’t sure, contact your carrier.
Then transfer your iCloud backup to your new device.
Transfer your iCloud backup to your new device
- Turn on your new device. A « Hello » screen should appear. If you’ve finished setting up your new device already, learn what to do.
- Swipe left to right on the « Hello » screen. Follow steps until you see the Wi-Fi screen.
- Tap a Wi-Fi network to join.
- Follow steps until you see the Apps & Data screen, then tap Restore from iCloud Backup > Next.
- Enter your Apple ID and password.
- Choose a backup. Make sure it’s the right one by looking at the date and size of each. After you choose, the transfer starts. If you’ve purchased iTunes or App Store content using multiple Apple IDs, you’ll be asked to sign in to each. If you can’t remember the passwords, you can skip this step by tapping Don’t have an Apple ID or forgot it.
- Stay connected and wait for the process to complete. If you disconnect from Wi-Fi before the process finishes, the restore process pauses until you reconnect. Restoring from a backup can take a while, depending on the size of the backup and the network speed.
If possible, keep your device connected to Wi-Fi and plugged into power until your cloud content downloads to your device. Cloud content includes anything stored in the cloud instead of your backup, like photos and music. This content will download automatically in the background. Depending on the amount of content, this could take a few hours or days to finish.
If you normally use iTunes to sync content, you can also connect your device to your computer and use iTunes to sync any additional content. If you haven’t set up iCloud Keychain, you might be asked to enter passwords for email, social media accounts, and other apps.
