Change Your iPhone's System Language in Settings

To change the language your iPhone displays, open Settings, tap General, then tap Language & Region. At the top, you'll see iPhone Language with your current language listed. Tap it, scroll through the list of available languages, and select the one you want. Your iPhone will restart briefly to explore the change, and all menus, buttons, and system text will switch to that language.

The process is the same whether you're using an iPhone 15 or an older model running iOS 16 or earlier. The Language & Region menu is always in the same place. If you don't see it, make sure you're in Settings > General — not in a different section like Display or Accessibility.

Key Takeaways

  • Go to Settings > General > Language & Region and tap iPhone Language to see all available options.
  • Selecting a new language restarts your iPhone and changes all system text, menus, and built-in app labels to that language.
  • Your personal files, photos, and third-party apps keep their original language unless those apps have their own language settings.
  • You can set a different region for dates, times, and measurements without changing the system language itself.
  • If you change your mind, you can switch back to your original language using the same menu at any time.

What Changes and What Doesn't When You Switch Languages

When you change your iPhone's system language, Apple's built-in apps — Messages, Mail, Calendar, Weather, Stocks, and others — all switch to the new language. Siri, voice commands, and keyboard suggestions also follow the system language. Settings labels, notification text, and error messages all change too.

Your personal content does not change. Photos, videos, notes, and documents you created stay exactly as they are. Third-party apps like Instagram, TikTok, or Spotify may or may not switch languages — it depends on whether each app has its own language setting. Many apps detect your system language and switch automatically, but some stay in English or whatever language you originally set them to. If an app doesn't switch, you can usually change it inside that app's own settings.

Setting Region Separately from Language

Your iPhone lets you set the language and region independently. Language controls what text you see. Region controls how dates, times, phone numbers, and measurements display. You might want English language but UK region (so dates show day/month/year instead of month/day/year), or Spanish language but US region (so temperatures show in Fahrenheit).

To change only the region without changing the language, stay in Settings > General > Language & Region and tap Region instead of iPhone Language. Select your preferred region from the list. This change takes effect when ready without restarting your phone.

Adding a Second Keyboard in a Different Language

If you want to type in multiple languages without switching your entire system language, add a second keyboard instead. Go to Settings > General > Keyboard > Keyboards, then tap Add New Keyboard. Choose the language you want to type in — you can add as many as you need. When you're typing, a globe icon appears on your keyboard; tap it to switch between languages.

This approach is faster if you only need to type in another language occasionally. Your system language, menus, and all your apps stay in English (or whatever your main language is), but you can quickly switch to type in Spanish, French, Mandarin, or any other language your iPhone supports.

Troubleshooting When Language Won't Change

If you tap a language and it doesn't change, your iPhone may still be downloading the language pack. Some languages require additional files to work properly, especially if you're using voice features or dictation. Wait a few minutes and try again. If the language still doesn't appear in your list, restart your iPhone by holding the power button and swiping to power off, then turning it back on.

If a language you need isn't in the list at all, it may not be supported on your iPhone model or iOS version. Check Apple's support site to confirm which languages your device supports. Very old iPhones running iOS 15 or earlier have fewer language options than newer models, though the most common languages are available on all versions.

Changing Language for Siri and Dictation

When you change your system language, Siri automatically switches to that language. However, you can set Siri to a different language than your system if you prefer. Go to Settings > Siri & Search and tap Language. You'll see a list of languages Siri supports — choose one independently of your system language.

Dictation (the microphone button on your keyboard) also follows your system language by default, but you can change it separately in Settings > General > Keyboard > Dictation. This is useful if you speak one language but want your iPhone's menus in another, or if you want Siri to understand your accent better in a specific language.

Frequently Asked Questions

Will changing my iPhone language affect my Apple ID or iCloud account?

No. Your Apple ID, iCloud data, and all your accounts stay the same. Changing the language only changes how your iPhone displays text. You can sign in and use all your accounts normally in any language.

Can I have different languages on different user accounts on the same iPhone?

iPhones don't have separate user accounts the way computers do. Only one person can use the iPhone at a time, and the language setting applies to the whole device. If you share an iPhone with someone else, you'll both see the same language.

What happens to my apps when I change the language?

Built-in Apple apps switch to the new language automatically. Third-party apps usually switch too, but some may stay in their original language. If an app doesn't switch, check its own settings — many apps have a language option inside the app itself, separate from your system language.

Can I change the language back to English if I accidentally switched to something I don't understand?

Yes. Even if you can't read the menu labels, the process is the same: tap the gear icon (Settings), look for the second option in the list (General), tap the third option (Language & Region), tap the first option (iPhone Language), and select English from the list. The layout doesn't change, only the words.
