Is China Unicom’s network speed too fast or is it consuming too much data?

Nowadays, smartphones are generally used. There are many software on the mobile phone that will run in the background or automatically update. In this way, data will be used inadvertently. If you need to know your data usage, , you can log in to the homepage of China Unicom's online business hall and click Call Bill Inquiry>Bill Inquiry>Detailed Invoice Inquiry>Internet Traffic to check the details of mobile Internet access within six months. For details, please contact China Unicom customer service at your home location.
