You can have multiple keyboards installed on your T-Mobile mobile phone or tablet, one for each language you use, and you can switch between those keyboard languages with the touch of a button.
Having multiple keyboards on your T-Mobile is useful for typing in multiple languages and being able to use the appropriate autocorrect for each language.
If, on the other hand, what you need is to change the keyboard language of your T-Mobile device and have a single keyboard language, you can also discover how to do it, search for your T-Mobile model and follow the steps we indicate.
