Second, if the payment is unsuccessful, there are two situations that will lead to this phenomenon. Suggestions can be handled in the following ways.
Case 1 cannot be paid due to abnormal number status. For example, the prepaid number is locked or the number has been cancelled (empty number), which makes it impossible to pay. It is suggested to call 100 10 to check the number status and consult and handle it.
In case 2, users pay through third-party channels such as WeChat or Alipay, and the system of such channels is busy, resulting in payment failure. It is suggested to change the examination time or pay through Unicom's official mobile phone business hall or online business hall.
