Related to this issue, I have two questions:
|
It wasn't always that way. It was disabled because delivery reports can cost money as per this commit.
As far as I know, 'read confirmations' are not something supported by the SMS protocol. |
Just googling, I found that 'read confirmations' are handled by the RCS protocol, which uses internet. |
Yep :) |

Steps to reproduce the bug
Preliminary remark:
As far as I know, the sending of an SMS is confirmed in two stages:
1st tick ≙ transmission confirmation (the SMS was sent successfully)
2nd tick ≙ confirmation of receipt (the SMS has been received by the recipient).
I assume that the network protocol(s) used are used for this purpose and is basically no different than if I as a user manually prefix the SMS with a code corresponding to my provider (e.g.
*T#
, "Deutsche Telekom").A confirmation of receipt should not be confused with a read confirmation. Read confirmations are not supported by the protocol(s) used.
At the time the SMS is sent, the recipient may not be reachable via the network. This is the case if the device is switched off or is outside a radio cell (dead zone).
Expected behavior
When the receiver is available in the network again, the receiver device should send the confirmation of receipt. The missing 2nd tick should now be set.
Actual behavior
There is no subsequent confirmation of receipt if the recipient device is outside the network at the time the SMS is sent.
