There is no information prompt when the school news passes out of the school gate.

1. Ensure that the school newsletter service opened by the mobile phone is within the normal validity period;

2. Whether the mobile phone model supports SMS function; Whether the balance of mobile phone number is insufficient; Short messages are lost because they are not turned on for a long time;

3. Misdelete: As the received SMS number is the enterprise code (not the mobile phone number), it may be mistakenly deleted as a harassing SMS.
