I use Unicom number, and recently I found that I have to deduct money for sending text messages three times. What happened?

1. Unicom's deduction fee has been transparent. If you have any questions about the phone bill, you can log in to Unicom's online business hall/homepage and click "phone bill inquiry" > "bill inquiry" > "historical bill" to clearly understand the number consumption;

2. If you still have questions after the inquiry, you can consult the detailed list to understand the specific usage, or consult the local manual customer service or business hall for verification.
