When you are trying to accomplish something unfamiliar on your iPhone and think that you are doing it correctly, only to achieve an unexpected result, then it can be frustrating.
One such task involves calling someone in another country if you aren’t regularly making international calls. The Dial Assist feature that is offered by a number of major cell phone carriers like Verizon and AT&T can simplify the otherwise confusing international calling process.
But if it’s causing problems, then you can turn off Dial Assist on your iPhone by going to Settings > Phone > and scrolling all the way to the bottom, and disabling the Dial Assist setting.
The Dial Assist feature on your iPhone attempts to automatically add the international and local prefixes 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.

If you have seen a blue clock on your iPhone and wondered what it meant, then this article can provide some insight on that topic.
What Does Dial Assist Mean on an iPhone?
Perhaps the most common reason that people come to this Web page is that they have been exploring the menus on their device and stumbled upon the Dial Assist setting.
The menu describes the dial assist feature on the iPhone as “Dial assist automatically determines the correct international or local prefix when dialing.”
If you live in the United States then you are probably familiar with the need to dial area codes in front of phone numbers so that you reach the correct person. The phone number 111-555-5555 is going to put you in touch with a different person than 222-555-5555, for example.
If you are trying to call someone in a different country, however, then you also need to use a country code. Dial Assist automatically adds the local prefix and/or country code correctly.
But the iPhone automatically figuring out country codes can cause problems for contacts that are saved with the correct country and local prefixes, which is why many people need to shut off the dial assist setting.
Some of the icons at the top of your iPhone screen can be tough to decipher. Our clock icon on iPhone tutorial can show you what that one means and how you can remove it.
