Why does China Unicom display recharge failure after paying the phone bill?

If you recharge online, online payment may fail for the following reasons:

1. The computer is not connected to the Internet or its access area is limited;

2. The version of IE is too low, the number of password bits is insufficient, and the IE parameters are set incorrectly;

3. After the payment is confirmed on the Unicom 100 10 website, enter the PayEx secure payment platform. When you choose a bank for online payment, it takes about 30 seconds or more to connect to the security system for online payment (that is, after clicking the payment channel of the selected bank). If there is a network communication failure (the internet is too slow, the modem is disconnected, or the access in the LAN is limited, etc.). ), the submission will be interrupted or failed;

4. When you connect to the security system for online payment (that is, after clicking the selected bank payment channel), the connection page will be refreshed, and a system prompt will appear: "Duplicate order error". This setting is to prevent some irregular behaviors on the Internet from causing bank settlement. Please place an order again for online payment;

5. The entered payment card account number and password are incorrect;

6. The payment function used has not been certified by the bank;

7. The amount on the payment card is not enough to pay the expenses;

8. Using an incorrect payment card, etc.

If you still can't recharge the phone bill in the above situation, it is recommended to contact Unicom customer service for more help.
