Silent, what can Unicom do by sending SMS to handle traffic?

If the traffic packet cannot be processed, the following situation is not excluded: 1. This kind of traffic packet service has not been opened in the number attribution; 2. The mobile phone package does not meet the processing conditions; 3. The mobile phone is turned off and can only be processed when it is turned on normally; 4. The mobile phone package has a traffic packet, which conflicts with the traffic packet to be superimposed; 5. The treatment method is wrong. If the instruction is sent incorrectly, please check the operation mode again. 6. The system is busy. If the system is busy due to the current number of people visiting the website, you can try again later. If the above situation has not been solved, you can contact Unicom's manual customer service to check the specific reasons.
