What number should Unicom dial to send you a text message directly to show how much the phone bill is left?

You can directly dial1001011to check the phone bill and traffic, and a short message will be sent after the call. At the same time, you can also download Unicom's mobile phone business hall, you can query the phone bill and traffic with one click, and you can also query the historical bill. I hope it will help you, and thank you for your support and understanding.
