iPhones are known as the most user-friendly electronic gadgets and one reason for that is how easy they are to personalize to your preferences. One of the things you can personalize is changing the language to something different than what you chose when you set up your iPhone.
How to change the language on an iPhone
If you are fluent in multiple languages or if the language on your iPhone is set incorrectly, you can change it by following the methods explained below.
iOS lets you switch to a preferred language in several sections of your iPhone. You can change the language you communicate with Siri in, switch between multiple languages while typing on the native keyboard, or change the language of your device entirely so that all options and elements on your iPhone display your preferred language instead of the language it’s currently set to.
Siri isn't designed to work in multiple languages on iPhone, meaning you can only interact with Apple's voice assistant if you speak the same language as the one currently selected for Siri. If you want to interact with Siri and ask questions in a different language, you can switch to a preferred language by following the steps below.
