This is one of those posts which is likely to be old news for most people. However, for the rest, I hope you find it useful. When you send a text message (aka SMS) you can ask for a delivery receipt. Did you know that already? OK then, nothing to see here.
A delivery report is an automatic timestamped message confirming that your text has reached the recipient’s phone. It does not tell you that the message has actually been read.
Depending on your network provider you can either turn this feature on in your phone’s Settings, or you may have to start the body of each message with the three character string *0# (that’s star zero hash). The recipient does not see this string in the message.
You can use delivery reports as an indirect way of learning that someone has arrived safely after a plane journey. Simply send them a message during their flight, and then when they turn on their phone at their destination, you will receive automatic notification.
