What does the loss of short message information in college entrance examination mean?

It turns out that my mobile phone is L7, marked * \ \ *. Later, I asked the technicians, and they said that the format of my mobile phone did not match the format of the mobile phone that sent me the message. Another possibility is that the signal is not good and the message cannot be refreshed in time. I suggest you call your classmate and ask if you have received the information marked with the name of your graduation school at the end, and you will understand the general content.
