2 Dial Assist
Dial Assist is a little-known feature on iPhones that’s pretty nifty for iOS users traveling abroad. It also happens to be a fairly vague feature, and Apple doesn’t appear to have any online support documents about it. Basically, Dial Assist automatically enters international and local prefixes to the phone numbers that you call. Here’s how to access it.
- Open Settings.
- Navigate to and tap on Phone.
- Toggle Dial Assist on (or off)
When traveling abroad, it’s important to include the correct prefix when making calls. It’s switched on by default, but there can also be issues and redundancy problems with it when you’re out-of-country — so it’s handy to know how to turn it off.
