When it comes to giving away or selling your iPhone, you can not just turn it off, remove the SIM card and hope it's all right. There is valuable data on your iPhone, and you have to get rid of it. And if you do not take all the necessary steps, it is likely that you will not even be able to work with the device. Selling it could threaten your seller's reputation.
If you currently have an upgrade plan with Apple or your wireless service provider, you probably will not sell or give away your iPhone to get a newer iPhone X R X S or X S Max, or even a hot new Android phone, but you still have to wipe it clean before you give it back. [1
9659002] For those of you who have fully paid for your iPhone, you want to sell it to pay for the new device. If you do not need the extra money, you can give it to a friend, family member, or charity, or you can just keep it as a spare phone.
No matter what you do with your iPhone, if you do not keep it as a backup or second phone, here's everything you need to do before you remove it safely, including backup, wipe, and carrier unlocking.
Go to the Watch app on your iPhone, tap your watch at the top of the main page and select "I" next to it, then tap "Disconnect Apple Watch." If you have a GPS + Cellular model (Series 3 and 4), you also have to choose "Remove Carrier Plan" – which does not terminate your plan, but just puts you on another iPhone. Enter your Apple ID password and tap
again to confirm. Step 2: Log off iMessage (when switching to Android)
To sign out of iMessage, make sure that your SIM card is still in the device and that you are connected to your mobile network. Then go to the Settings app on iPhone and tap Messages. Finally, disable "iMessage" at the top of the page. You also want to go into the "FaceTime" settings and do the same. If for some reason you forget to do these things, you can still log out of Apple's website.
