How can I protect my rights when China Unicom arbitrarily deducts fees?

Unicom will deduct the fee according to your actual usage. If you have any questions about the deduction:

1, you can find out the relevant details (including real-time phone bill, account balance, historical bill and call bill) in the mobile phone business hall-service-inquiry-phone bill business inquiry.

2. You can check the details of Internet traffic in the mobile phone business hall-service-inquiry-traffic business.

If you have any questions, you can contact the local manual customer service for consultation.
