It's a problem with Apple and how O2 messaging works.
O2 network doesn't support delivery reports in the way Apple think, so you get a fail message.
To get an accurate report you need to start all texts with *0# and ignore the system message.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
