How to realize that S60 mobile phone also has a sound prompt when it receives the prompt that the SMS has been sent?

At present, there seems to be no software to realize this function. The mobile phone is only responsible for submitting the short message content to the mobile short message service center for queuing. If the server is available, it will be sent to the other party's mobile phone immediately. If not, it will be delayed. The sender's mobile phone has no way to know whether the message has arrived. You can turn on the receiving report function in SMS settings, which will prompt you whether to send the SMS immediately or delay it.
