Mobile broadband has been renewed, why do you still receive the information that broadband is due for renewal?

After paying the internet access fee, it will still show that the network has expired. Maybe the system has not been updated. You can consult the relevant departments. If it is mobile, you can call 10086 without displaying the internet fee. If it's that telecom, you should call the number 10000. If it is the Great Wall, you should call the broadband service hotline of the Great Wall to solve this problem.
