China Mobile sends text messages for three yuan.

There are three explanations for this situation:

1. There may be something wrong with your mobile phone system, and there are many status reports.

2. When your friend sent it to you, he pressed it quickly and pressed it a lot.

3. There is something wrong with the mobile system. These things are not managed by backstage people, but by the system, and the staff are managing the backstage system. Occasionally, this phenomenon can't be said to be moving to black our money.
