How to send text messages? I can't send it urgently.

There are short messages in the menu of the mobile phone, and there are handwritten messages or edited messages in the short messages. After you enter, you can directly select the functions you can use (such as strokes and pinyin) for editing, and finally press Done, then press OK, then enter the mobile phone number you want to send according to the prompt, and select Send, and you will be ok. Really dizzy. There are people who can't send text messages.
