Why do mobile phones always send some inexplicable short messages about on-demand services?

The most reliable way is to call the customer service, and then ask them to check all the paid services for you, and then cancel them all. If they don't help you, you can complain. Of course, they will definitely help you. Mine has the same problem as yours. I just finished it. Note: If it's not someone else's problem, it may be your mobile phone software or the game. Don't mess around. I wish you success!
