How to Change the Language on Your iPhone
Changing the language on an iPhone is one of those settings that sounds straightforward — and mostly it is — but there are a few layers worth understanding before you dive in. The change affects more than just menus and buttons, and depending on your setup, the experience can vary in ways that aren't immediately obvious.
What "Language" Actually Controls on iOS
When you change the system language on an iPhone, you're changing the primary language used across iOS itself — menus, settings labels, built-in apps like Calendar and Messages, keyboard suggestions, Siri, and more. This is different from:
- Keyboard language — the language your physical (on-screen) keyboard types in
- App language — some apps have their own language settings independent of iOS
- Region format — which controls date, time, and number formatting separately
These are distinct settings, and changing one doesn't automatically change the others. It's worth knowing which one you actually need to change before you start.
How to Change the iPhone System Language
The path is the same across modern iOS versions:
- Open Settings
- Tap General
- Tap Language & Region
- Tap Add Language (if your target language isn't listed) or tap the language you want and drag it to the top of the list
- Confirm the change when prompted
Your iPhone will restart the interface in the new language. This typically takes a few seconds. After the restart, system menus, built-in apps, and Siri will operate in the selected language. 🌐
One thing to note: if you've never used that language on your device before, iOS may need to download a small language pack. This requires an internet connection and usually completes quickly.
How to Add or Change a Keyboard Language
Changing the system language does not automatically add a keyboard for that language. If you want to type in another language, you need to add a keyboard separately:
- Open Settings
- Tap General
- Tap Keyboard
- Tap Keyboards, then Add New Keyboard
- Select the language and keyboard layout you want
Once added, you can switch between keyboards while typing by tapping the globe icon (🌐) on the keyboard bar. This is useful if you regularly communicate in more than one language without wanting to change your entire system language.
Changing Language for Individual Apps
Some apps — particularly third-party apps built with localization support — have their own language settings inside the app itself. But since iOS 13, there's also a system-level option:
- Open Settings
- Scroll down to the specific app (listed at the bottom of Settings)
- Tap on the app and look for a Language option
Not every app surfaces this option. Whether it appears depends on how the app was built and whether the developer included support for per-app language settings in iOS. Apps that haven't been updated or localized for multiple languages won't show this toggle.
Changing Siri's Language
Siri has its own language and dialect settings, separate from the system language:
- Open Settings
- Tap Siri & Search (or Apple Intelligence & Siri on newer iOS versions)
- Tap Language
- Choose from the available options
Siri supports a range of languages and regional dialects. Changing Siri's language here affects voice recognition and responses, independent of what language your keyboard or system menus are using.
Region Format vs. Language: Not the Same Thing
This trips up a lot of people. The Region setting (found in the same Language & Region menu) controls how dates, times, currencies, and measurements are displayed — not which language text appears in.
For example, you could have your iPhone system language set to English but your region set to Germany, which would display dates in DD/MM/YYYY format and use the euro symbol by default. These two settings work independently, so you can mix them to match your actual location and language preferences without one overriding the other.
Variables That Affect Your Experience
A few factors shape how smoothly a language change goes and what it actually changes on your device:
| Factor | What It Affects |
|---|---|
| iOS version | Menu paths may differ slightly; older versions have fewer per-app controls |
| App localization | Whether third-party apps respond to the system language change |
| Downloaded language data | Some languages require an internet connection to download supporting files |
| Siri availability | Not all languages are supported for Siri in all regions |
| Keyboard layout preferences | Different languages have different keyboard layout options (QWERTY, AZERTY, etc.) |
When Multiple Languages Are Listed
iOS allows you to rank multiple languages in the Language & Region settings. The top language is your primary one, but iOS will fall back to the next language on the list if an app or feature isn't available in your first choice. This is particularly useful for multilingual users who work across two languages regularly.
The order matters. If you have English at the top and French second, apps that don't support French will default to English rather than showing an error or defaulting to an unrelated language.
A Note on Reverting
If you change your system language and find the menus are now in a language you can't read well enough to navigate back, the path back is the same — Settings → General → Language & Region — just follow the same icon patterns. The settings icons don't change with language, which makes it easier to reverse the process even if you can't read the labels.
How much any of this matters in practice depends heavily on which languages you're working between, how the apps you use most handle localization, and whether you need system-wide changes or something more targeted — like just a keyboard or a single app. 🔧
