Dial Assist is a handy feature on your iPhone that automatically adds the correct country or area code when making calls. If you travel a lot or call international numbers often, it can save you the hassle of figuring out the right dialing prefix. Here’s how to enable or disable it on your iPhone 14 running iOS 16.
Enable or Disable Dial Assist on iPhone 14
- Open the Settings app.
- Scroll down and tap Phone.
- Scroll to the bottom and find Dial Assist.
- Toggle the switch on to enable or off to disable it.
When it’s on, your iPhone will automatically detect and apply the right prefix when dialing contacts, especially those saved without country codes.
When Should You Use Dial Assist?
- Keep it ON if you’re often unsure about dialing codes for international or out-of-state numbers. It’ll simplify your calling process and reduce errors.
- Turn it OFF if you’re noticing call failures, billing issues, or incorrect numbers being dialed—especially with certain carriers or during international travel. In these cases, manually entering the full number might be more reliable.
A Note About Carrier Charges
Dial Assist doesn’t bypass carrier fees. Even if the number is dialed correctly, international call rates still apply. U.S. carriers like AT&T, Verizon, and T-Mobile support Dial Assist, but always check with your carrier about international rates to avoid surprise charges.
