    I am interested in how sending delivery reports works. The report is generated over the recipient's phone and sent back? What conditions must be met for the delivery report to be returned to the sender of the SMS? How does it even work?

    So the report has nothing to do with the physical delivery of the message?

    It is related because the report is sent over the network only when the recipient's phone confirms that it has received the message. When the phone is turned off or out of range, a delivery report will not be generated. Of course, this report is not about reading the message, only about delivering it.

    The reading report is available for MMS. But it probably works in a similar way to reports about reading an email, because in order to read such a message, it must be downloaded.

    With the Hushsms program, you can send an empty text message, where the owner does not know that he has received it and we have confirmation that his phone is active.

    Confirmed by phone or SIM card? What must be met for the report to be generated?

    For now, we are writing what can be derived logically. I am more concerned with the technical approach to the matter. How it works exactly. I do not mean bit by bit explaining how the report generation is done. What generates them and on what basis.

Topic summary

SMS delivery reports are generated by the mobile network operator when the recipient's phone confirms receipt of the message. The report is sent back to the sender only if the recipient's device is powered on and within network range. If the phone is off or out of range, no delivery report is produced. The delivery report indicates that the message was delivered but does not confirm that it has been read. For multimedia messages (MMS), reading reports function similarly, requiring the message to be downloaded for confirmation. Additionally, tools like Hushsms can send undetectable messages to confirm the recipient's phone status.
