Why can't my school newsletter receive school homework information?

According to the information you provided, for example, the users of Guangdong Zhuhai Unicom could not receive the short message of the school newsletter. The following methods are recommended for investigation:

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; The mobile phone number does not belong to Guangdong Unicom users or the balance of the user's mobile phone card is insufficient to receive short messages; 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.

If the problem or the above situation cannot be solved unless all the above reasons are eliminated, it is recommended to contact your customer service at the place of origin.
