Mobile sends a text message saying that it is not working properly.

If 10086 sends a text message to remind you that the user status of the mobile phone account is abnormal, first of all, this situation is considered as arrears. How much money you owe must be paid back. Another possibility is that the user has received some abnormal calls or been hacked, or complained, or you often call. In this case, you can go to the business hall with your ID card and ask what the reason is.
