What is dial assist iphone?

Dial Assist is a feature on iPhone that helps users automatically dial international prefixes or country codes when making calls to contacts outside of their own country. This feature is particularly useful for users who frequently make international calls and don't want to manually enter country codes every time.

To enable Dial Assist on iPhone, go to Settings > Phone > Dial Assist and toggle the switch to enable it. Once enabled, iPhone will automatically add the appropriate international prefixes or country codes when dialing numbers from your contacts or recent calls list.

Dial Assist is available on iPhones with iOS 11 or later and can help save time and ensure that calls to international numbers are properly dialed.
