I have an iPhone SE with iOS 11.3.1 .
If I send a normal SMS (that is one that does not require internet, the old SMS we had) using iMessage then no delivery report comes. This is not a network issue because Android or non smart phones do get delivery reports.
As far as I have read, there is no way to turn on this feature on iMessage for normal SMS. Is there any other app that I can use to send normal SMS from iPhone that can show delivery reports?
Do note that I am not asking for apps that require data connection. I am just looking for any alternate program for sending network based SMS.
A related question has been asked about four years ago here at How can i get delivery confirmation for sent sms? . However, there no way out could be found.
