Switching your iPhone's display language takes less than a minute, but if you're navigating unfamiliar menus or setting up a device for someone else, finding the right toggle can feel like searching for a needle in a haystack. Apple buries language preferences inside iOS system settings, and a single misplaced tap can leave your entire device displaying words you don't understand.
Whether you're traveling abroad, learning a new tongue, or fixing an accidental switch, here's how to change the language on your iPhone cleanly and correctly. We'll cover standard system updates, region formatting, app-specific language overrides, and common troubleshooting steps that basic tutorials miss.
The Core Steps to Change Your iPhone Language
Updating your device-wide display language alters menus, button labels, notifications, and built-in Apple applications. Follow this exact sequence to update your device.
- Open the Settings app from your home screen or App Library.
- Scroll down and tap General.
- Tap Language & Region near the middle of the screen.
- Tap Add Language (represented by the plus icon in iOS 16 and later, or clearly labeled text in older software versions).
- Search for or select your target language from the list.
- A prompt will ask if you want to make this your primary language. Tap Use [Language].
Your screen will briefly go black with a spinning gear icon as iOS refreshes its system UI. Once it reopens, your entire operating system will run in your chosen tongue. To see the full picture, check out the detailed report by The New York Times.
Managing Preferred Language Order and Fallbacks
iOS doesn't just rely on a single language; it uses a prioritized language list. If an app or website doesn't support your primary choice, your iPhone automatically defaults to the next language down on your list rather than crashing or defaulting to English.
To manage this hierarchy:
- Go back to Settings > General > Language & Region.
- Look at the Preferred Languages section.
- Tap Edit in the top corner, then drag the grab icons (the three horizontal lines) next to each language to reorder them.
- Alternatively, swipe left on any language in the list to delete it entirely from your device.
According to Apple Support, keeping your ordered list clean ensures third-party applications render text correctly without unexpected localization glitches.
Customizing Region and Formatting Independently
Language and region are linked by default in iOS, but you don't have to keep them paired. If you live in Spain but prefer your phone menus in English, or if you want French menus with US date formats, you can separate them.
In Settings > General > Language & Region, you'll see a Region setting at the bottom. Tapping this changes:
- Measurement System: Metric vs. US customary units.
- First Day of the Week: Sunday vs. Monday on calendar grids.
- Date and Time Formats: DD/MM/YYYY versus MM/DD/YYYY.
- Number Formatting: Decimal separators and currency symbols.
Changing your region doesn't force your apps to change their display language, giving you granular control over your digital environment.
Setting Individual Languages for Specific Apps
Starting with iOS 13, Apple introduced the ability to run individual apps in different languages without changing your entire phone system. If you want your system menus in English, but prefer your banking app in Spanish and your news app in German, you can configure this per app.
- Open Settings.
- Scroll down and tap the specific app you want to modify (e.g., Safari, Maps, or a downloaded app).
- Under the Preferred Language section, tap Language.
- Choose your desired language from the list of options supported by that specific developer.
If an app doesn't show a language option, it means the developer hasn't bundled localized strings for that language inside the app binary.
Adjusting Keyboards and Dictionaries
Changing your display language doesn't automatically install matching keyboards or spellcheck dictionaries. If you try to type in your newly selected language, you might find autocorrect constantly fighting you.
Adding a Keyboard
- Go to Settings > General > Keyboard > Keyboards.
- Tap Add New Keyboard...
- Select the keyboard matching your new language.
Checking Dictionaries
- Go to Settings > General > Dictionary.
- Check the boxes next to the dictionaries you need so your iPhone can provide definitions and spellcheck support in multiple tongues.

Troubleshooting Common Language Glitches
Sometimes iOS gets confused during a language transition, leading to mixed UI text or unresponsive menus. Here's how to fix the most frequent hiccups.
Apps Displaying Mixed Languages
If half your apps are in English and the other half are in your new language, the app developer may not support full localization. Alternatively, your iOS cache needs a refresh. Restart your iPhone by holding the side button and volume down button, then swiping to power off.
Can't Find Your Language in the Menu
If your specific dialect or regional variant isn't listed, check if it's available under a broader regional category. For example, specific regional variations of Spanish or Portuguese have unique sorting rules in iOS. Make sure your software is fully updated via Settings > General > Software Update, as Apple frequently adds new localization packs with major point releases.
Accidentally Locked Out in an Unreadable Language
If you tapped the wrong option and your phone is now in a script you cannot read, don't panic.
- Open Settings (look for the gray icon with spinning gears).
- Look for the gear icon labeled General (it has a matching gear symbol).
- Scroll down to find the item with a rectangular icon and a small gear/sliders (Language & Region). It's usually near the middle of the general settings list.
- Tap the top option in that menu, drag your correct language to the top, and confirm.
Frequently Asked Questions
Will changing my iPhone language delete my photos or data?
No. Changing your display language only alters how text and menus are rendered. Your personal files, photos, messages, and app data remain completely untouched.
How many languages can I add to my iPhone?
You can add up to ten languages to your preferred language list, though device performance is unaffected regardless of how many you store.
Does changing the system language affect Siri?
Siri has its own dedicated language setting. To change what language Siri speaks and listens to, go to Settings > Siri & Search > Language.
Why are some third-party apps ignoring my new language?
Not all app developers translate their software into every language Apple supports. If an app lacks translation files for your chosen language, it will fall back to its default language (usually English).
