Can't Unicom receive the information because of the arrears of mobile phones?

When you are in arrears and semi-downtime, users can only answer and receive short messages, but can't make phone calls, send short messages or surf the Internet. Arrears for downtime means that users fail to pay fees within the specified time (the 5th to 25th of each month is Unicom's payment period), and Unicom will stop processing the user number on 26th. If you haven't paid off the arrears of last month on the 29th, you will enter a state of complete shutdown. During the total shutdown, the mobile phone number will not be used normally, that is, you can neither make a phone call, answer a phone call, send a text message, surf the Internet, etc. , and can only be turned on and used normally after the arrears are paid off.
