How did you set your phone to English after the iphone escaped from prison? Including text messages. Then how to set it back?

Here is my answer:

Generally speaking, any mobile phone that needs to change languages on the iPhone does not need to be jailbroken.

If you change the language to English, please enter the main interface of iPhone, select Settings, touch General, and scroll up. You will find a "multilingual environment". Touch it, there is "English" under simplified Chinese. Select it to switch to English.

If you want to change the language to Chinese, please enter the main interface of iPhone, select "Settings", touch "General" and scroll up. You will find "international language". Touch it. English has "Simplified Chinese" on it. Select it to switch to Chinese.

That's my answer. If you have any questions, please ask them in time.
