Will China Mobile delay sending messages by 10 hour? This is a message between two mobile users.

SMS is a system similar to email, and sending and receiving are two different actions. Successful sending means that your message has reached the SMS center, but the SMS center may not send the message to the other party's mobile phone. There are many reasons, such as the other party's power off, the SMS storage is full, temporarily out of service area, and the network is busy. At this time, the short message will be stored in the short message center and will continue to try (it will also be marked in the HLR of the other party, for example, the other party will notify the short message center after turning on the phone). If the default time is calculated, the message will be saved for 7 days.
