My mobile phone has been ringing for a long time, but no news has come in.

Hello, your mobile phone should be a smart phone. Maybe some kind of software was downloaded from the mobile phone. You can always check your own expenses, which sometimes affects the initiative of your mobile phone to upload short messages, resulting in some expenses of your mobile phone number. If you suggest deleting some useless software through program management, it is really not feasible. I suggest you consult the mobile phone customer service.
