It's no surprise to anyone that Apple releases a new iPhone every year. Many existing iPhone owners will be looking to upgrade to Apple's latest phone, so we've created a handy guide showing you how to backup your phone's data, wipe/reset your phone, and transfer service from your cell phone provider.
Backing up your iPhone's data ensures your pictures, videos, apps, settings, and everything else will be there waiting for you when you migrate everything to your new phone. Your data can be backed up to either iCloud or iTunes. You might be wondering which destination makes the most sense for your backup data.
To be on the safe side, you might want to consider backing up to both iCloud and iTunes. It's better to be safe than sorry.
To remove your SIM card, you'll need to locate the hole next to your SIM card tray on the side of your phone. Insert a paper clip or SIM-eject tool to pop open the tray, remove the SIM card, and re-insert the empty SIM card tray.
Your phone's SIM card stores data about your account including phone number, security data, and more. Removing your SIM card makes it unable for your old phone's new owner to make calls from your phone number or use your data plan.
This will not only wipe all data from your phone, it will also remove the Find My iPhone feature and sign you out of iCloud on your old device.
Congratulations! You are now able to sell your iPhone.
