The fact that the contents of the iPhone is encrypted (AES-256), so it is enough just to delete the key, thereby making it impossible to access the data. That is, the removal system simply breaks a key to the lock of the safe. Actually, no, don’t — don’t break the key, and fills the keyhole molten metal, turning in a pretty safe iron cube that can’t be hacked without destroying the contents.

To your data, nobody can get it. No way. But to restore them you can not, even if you change your mind to sell the iPhone. The only way to get them back is to take from the backup you made with iTunes. After all, you did?!

Users of iPhone 6, iPhone 6 Plus and upcoming iPhones can not worry — the accomplishment of the first step at the same time and automatically removes all the data about credit cards and fingerprints. But the paranoid and owners of older handsets Apple can go to the settings, Touch ID & password and Password and Apple Pay (iOS 8) or Wallet and Apple Pay (iOS 9) and delete everything there manually. And don’t forget that if you paid something on the iPhone via Safari, the information could be saved in the settings of the browser on the iPhone. Go to Settings > Safari > AutoFill > Saved credit cards.

Otherwise, the new owner will be able to receive messages on your smartphone that will allow anything you have to hack (although in real life this is a very unlikely scenario).

To get rid of the Apple ID, just go to, select Password and security and Manage your trusted devices, and there — to Add or remove trusted device. If there is your iPhone, please remove it.

8. Remove the SIM card and clean the iPhone
