Selling your old device

When you’re selling an old iOS device, keeping things tidy is of paramount importance. If you plan to use the data on a new device, back it up first. (Ideally, restore it to the new device before you ship the old one, just in case.) Then in Settings on the device you’re selling, tap your name and sign out of iCloud. Then in General > Reset, select Reset All Settings. Once the device has erased everything and reset, shut it down in the usual manner, and remove the SIM. Note that if you forget to remove a device from iCloud, you can do so later in Safari for Mac at iCloud.com. At iCloud.com, you can remove a device you no longer own – another thing that it pays to keep tidy.
