Why didn't I receive the confirmation message when I joined the school newsletter?

If you do it in the same month, you won't receive the SMS until the end of the month or next month, because the school newsletter is the data collected and entered into the system by the school's mobile phone. After entering the system, the system will automatically trigger a confirmation message. If you haven't received the confirmation message for more than one month, you can call 10086 to transfer him to the group seat. The group seat will take care of it for you.
