To get the latest iOS carrier update on your iPhone or iPad, start by ensuring your device is up to date with the latest software updates. Here’s how:
Go to Settings.
Tap General.
Tap Software Update and make sure Automatic Updates is toggled on.
If there has been a recent over-the-air update, you may also need to accept new carrier settings. To check for this:
Go to Settings.
Tap General.
Tap About.
If you see a pop-up asking you to accept new carrier or network provider settings, simply accept the update. This will ensure you have the latest carrier settings for optimal performance.
