Why does Babu SMS platform sometimes send it at night and receive it the next day?

I guess you sent a short message about membership marketing. In order not to disturb the rest of mobile phone users, their short message gateway will be closed at night and opened at 8 am the next day, and the short messages sent during the period will be sent after 8 am. During this period, customers who need to send short messages for work can contact your customer service specialist to provide relevant information and apply for 24-hour short message sending service, provided that the information sent by customers is member information, and mobile phone users are willing to receive it without causing complaints.
