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.

You will need to enter that information manually as you place your call.
Step 1: Open the Settings menu.
Step 2: Scroll down and choose the Phone menu.
Step 3: Tap the button to the right of Dial Assist to turn it off. You have turned off Dial Assist when there is no green shading around the button. Dial Assist is turned off in the picture below.
