Why do I get a message that the application failed when ordering data packages through SMS?

When ordering a data package through text messages, the reasons for failed processing are prompted: 1. The original application for the mobile phone was a time-limited Internet package, and when applying for a data package again, the application failed. 2. Each traffic package can only be ordered once per month, and repeated ordering cannot be successful. 3. System problems. 4. You can also choose to apply through the online business hall or call 10000.
