What if Unicom shuts down without sending a text message?

If your China Unicom mobile phone number is down, but you haven't received the SMS prompt, it may be for the following reasons:

1. This number is in arrears and can be used normally after paying the arrears.

2. The number can only be used normally after it is reported to be down or suspended.

3. If there is any problem with the real-name registration of the number, you can bring your original valid ID card and mobile phone card to your Unicom business hall for real-name registration.

4. If the number is illegal and abnormal, and it is reported or stopped by the relevant state departments, you can go to Unicom's own business hall to verify and handle it.

If the above downtime does not exist, it is recommended that you contact Unicom's manual customer service for details.
