Mobile Internet charging traffic can be included in the basic package traffic, and the part that exceeds the package traffic is the billing traffic outside the package, and the fee cannot be cancelled. You can send "ATTX" to 100 10 to open the daily traffic short message to know the progress of traffic use, or log in to our online business hall/home page and click "phone bill inquiry" > "detailed list inquiry" > "Internet traffic"/"mobile phone online record" to inquire about the detailed list and records of internet traffic. If there are still objections after the inquiry, you can contact the customer service at your place of origin to solve them.
