Short message receiving problem

You will receive it as soon as the phone is turned on. Generally, such short messages floating in the sky will be kept in the background for 1-2 days. If the owner does not turn on the phone, the SMS will be automatically deleted from the system. This is to ensure the smooth flow of the SMS system, and you can't keep the SMS for you for too long, otherwise the system will easily cause redundancy and affect the SMS function of others.
