If you're not sure where your iPhone is, or you're worried it might have been stolen, then Find My iPhone can help you find it.
Find My iPhone will usually be turned on automatically when you first set up your phone. If you’re not sure if it’s on, you can go to Settings, tap your Apple ID at the top, and then make sure Find My iPhone is turned On.
Finding your iPhone on iCloud
The easiest way to track your phone is from the iCloud website, which you can use from any computer (but not an iPad or tablet).
Go to icloud.com/find and sign in with your Apple ID. Once you’re signed in, you’ll be shown a map and the location of your phone. Hopefully, that should help you locate it and get it back - if not, click on it, and you'll be given three options:
If you can’t get access to a computer, you might be able to use another Apple device to find it.
If you’ve got an iPad using the same Apple account, you can open the Find iPhone app, and it’ll show you a map and where your phone is.
You can perform the same actions as above on the iPad – play a sound, put it in Lost Mode or Erase iPhone. You can also tap the arrow or car icon to open up the Maps app with directions to the location of your phone.
You can also use your Apple Watch to help find it too. Swipe up from the bottom of your Watch screen to show the Control Center, and then tap the phone button.
This will make your paired phone start ringing, and you can follow the sound. You can also hold the button down to activate the phone’s torch, if that'll help.
If you have Family Sharing enabled on your Apple account, you can use the Find iPhone app on a family member’s phone to find, ring, lock or erase your phone just like on iCloud.com.
Another option is if you’ve shared your location with any friends or familly, they’ll be able to see where your phone is using the Find Friends app on their phone. This option doesn't let you wipe or lock the phone but will give you a map of its location.
