Why didn't Shandong Examinations Institute send short messages with qualified test scores?

Shandong Provincial Examinations Institute does not send short messages to qualified examination results:

I didn't send a short message about HKCEE results, probably because there was something wrong with the system or network. Generally speaking, it may be more troublesome for you to make your mobile phone better. If everyone's grades have come out and you haven't sent a text message, you can also go to the class teacher and ask Zheng for advice. After all, exam results are still very important.
