When you need to use another language more than just your mother language (English language), you will need to add them on to your BlackBerry Z10 for further studying or using. After you add more languages on the phone, you will see the phone picks up spelling errors or suggests words in other languages correctly for you.
So, would you like to use texts in more than just one language? Do the following instructions to learn how:
1. Head back to your BlackBerry Z10’s Home Screen.
2. Open the Settings app.
3. Here, choose Language and Input.
4. Tap on Input Languages.
5. Then select Add/Remove Languages.
6. Feel free to pick the language you want to use.
