How to Turn Off Dial Assist on an iPhone 7

The Dial Assist feature on your iPhone attempts to automatically add the international or local prefix when you are making a call that requires it. While this can be helpful in certain situations, you may discover that your own international phone usage might dictate another approach. For example, if you regularly travel internationally and have a lot of international contacts, you might prefer to simply save those contacts with their full phone numbers (country code, area code, phone number), thereby negating the need for Dial Assist.

Fortunately it is possible to turn off the Dial Assist setting on your iPhone 7 if you aren’t using it, or if it is causing problems. Our guide below will show you where to find and disable this setting on your device.


How to Disable the Dial Assist Option in iOS 10

The steps in this guide were performed on an iPhone 7 Plus in iOS 10.3.2. Note that turning off this option is going to modify a setting on your iPhone’s Phone menu so that the phone will no longer automatically determine the correct international or local prefix when you dial. You will need to enter that information manually as you place your call.
