How to Delete All Contacts on iPhone At Once

Your iPhone, by default, would only let you delete contacts from your contact book, one at a time. Although this will work for a few contacts, it is still unpleasant for those who would like to delete many contacts.

One of the ways to go through the process would be to delete them via iCloud. If you don’t want to go in this way, an even easier way is to use an app from AppStore.

This post will feature both ways of deleting multiple numbers so that you may choose what is good for you. All these methods work perfectly, and your choice should only depend on the right software’s ease of use and availability.
