I am a user of Nanchang Mobile. When I turn off my phone, others will send me messages. Will others receive the report of successful sending after the short message is sent?

If it is turned off, the other party's mobile phone will generally only display the words "Message Sent" and the sending status will be "Sending Paused".

Only when you turn on the phone, if the other party's mobile phone is set to send a report, you will receive the report, and the time of receiving the information is the first time you turn on the phone.
