Permanently Delete Your iPhone Contacts
There are several reasons why one might need to delete their iPhone contacts. Nonexistent numbers, to avoid a person, unknown contacts, reduce your phonebook size and many other privacy or security issues. Naturally, it's easy to erase or delete contacts from your smartphone. But the real challenge comes when you don't need to remove 10 or 50 contacts, but hundreds of them. However, iPhone doesn't allow you to delete contacts as a whole. Deleting all of those numbers one by one would take a long time. Doing this is certainly a tedious, repetitive and very impractical task.
