But, if you want to remove all the contacts altogether at once, the iPhone currently doesn’t provide a built-in option for it. You’ll need to open iCloud on a PC and delete them from there.
How to Delete All Contacts on iPhone?
There are two main ways you can delete your Contacts on the iPhone. One way is to delete a contact from the Contacts app. Through this app, you can only delete a single contact at a time. If you want to delete multiple contacts at once, you’ll need to access your iCloud. Let’s take a look at them in detail.
Using the Contacts app
Here are the steps to delete someone from the Contacts app: If you want to block a person, open the specific contact and tap on the Block this Caller option.
Through iCloud
Here’s how you can delete contacts at once through iCloud. Another way you can delete your contacts from iCloud is through the settings on your phone. But this doesn’t apply to contacts linked to email accounts. You can either choose to delete the contacts only from your iCloud drive or also delete them from your iPhone. Here are the steps to do so: If you have a Screen Time passcode, you won’t be able to follow the steps above because the passcode restricts such changes. So, make sure to turn off the passcode beforehand.
