How to check how many QQ messages are left in Unicom official website?

How many short messages are there in your Unicom? Connect Unicom's online business hall and log in your mobile phone number (in the right center of the whole page, you should know the business password, that is, you can modify the business password. If you forget it, you can call 100 10 to consult about the modification. Please remember this password, it will be used), and click on the phone bill-> detailed list query-> short message list (this month's) at the top of the webpage to see how many short messages you have used. Just compare the gifts (you should go to the online business hall every month to find out your business cost. It's definitely not good if you don't understand, hehe).
