Step 1: Open the Settings App

Open the Settings app on your iPhone.

The Settings app is your gateway to customizing and controlling various features on your iPhone. It’s typically represented by a gear icon and can be found on your home screen or app library.

Step 2: Scroll Down to ‘Phone’

Scroll down the Settings menu until you find the ‘Phone’ option, then tap on it.

The ‘Phone’ section contains various options related to calls, contacts, and voicemail settings. It’s where you can manage call blocking and identification, silence unknown callers, and, of course, enable Dial Assist.

Step 3: Toggle On ‘Dial Assist’

Locate the ‘Dial Assist’ option and toggle the switch to the On position.

When the switch turns green, Dial Assist is active. With this feature enabled, you won’t need to add international or local prefixes manually when dialing numbers. Your iPhone will do it for you!

Additional Information

When it comes to enabling Dial Assist on an iPhone, there’s not much to it – a simple toggle in the settings, and you’re good to go. However, it’s important to note that while Dial Assist is a helpful feature, it’s not infallible. You might occasionally encounter a number that doesn’t conform to the expected format, and Dial Assist might not recognize it. Therefore, it’s always good to double-check the number before hitting the call button.

Also, be wary of the potential for accidental international calls. If you’re not careful, Dial Assist could connect you to an international number without you realizing it, leading to possible charges on your bill. Always ensure that your phone plan accommodates international calling if you intend to use this feature frequently.

Another tip is to keep your contacts’ phone numbers saved in the full international format. This practice can help ensure that Dial Assist works flawlessly, making your calling experience as seamless as possible.
