Welcome to the Community Forum and thanks for your post. I'm sorry to hear that you are experiencing a problem with your SMS delivery reports not working on your Samsung S6.
Are you able to try your SIM card in a different handset to see if you are still having this problem? If you are still not receiving SMS delivery notifications using a different handset then I'll arrange for a new SIM card to be sent to you.
Please let me know.
