Excuse me, when sending a short message, the information report prompts the other party that it can't receive it temporarily. What's the matter?

It may be that the other party was not in the service area when the message was sent, or it may not be turned on. I can't send you the receipt of the text message anyway. If I wait a little longer, I will tell you that I can't receive it for the time being. Under normal circumstances, once the other party is turned on or returns to the service area, you will be notified when the message is received. If the network is busy, this information will be delayed, especially when roaming. The level of this information is relatively low, and it will only be sent when the network is idle.
