How do you know if the other party has received the message? Will it be displayed if it is hacked by the other party?

Not every operator has opened this service, and this function was first realized on the mobile network. I'm not sure whether Unicom and Telecom realize it.

In addition, the so-called SMS delivery reminder only realizes the reminder of delivery to the target SMS center, rather than the actual receipt of SMS by the other party's mobile phone, that is, the operator is only responsible for sending SMS to the other party's SMS center, and is not responsible for the receipt of SMS by the other party's mobile phone. Of course, not to mention whether the other party reads.

So you can still receive the information report if you are hacked by the other party, but the other party did block it on the mobile phone and could not receive it.
