Why does my mobile phone (Unicom) often spend a lot in a short time?

There is a trap message on your mobile phone. You can check your information fee, SP fee and value-added fee in detail. If these detailed records cannot be found in the business hall, you need to dial 100 10. Your tone should be tough. This is the service you deserve. I've been in your situation.

When you find it, call the complaint number. First, call 100 10 to complain, and remember the customer service number. If it is not handled, call 100 10 to complain about customer service inaction. If there is no result, call 12300 to complain. This is the complaint telephone number of the Ministry of Information Industry in various provinces.
