If you want to remove all of your contacts from an iPhone, there are a few different ways to go about it. The first option is to use the iPhone’s built-in contact manager. Open the app and select the “Contacts” tab. Tap on each contact and choose “Delete” from the menu options. If you don’t want to use the built-in contact manager, you can also use a third-party app like Contacts Plus or Clear Contacts. Both apps offer a simple interface that lets you delete all of your contacts at once. Finally, if you just want to remove specific contacts from your iPhone, you can do that too by using the “Add Contact” feature in the Phone app. Just enter in the person’s name and phone number and hit “Add.” ..
