O2 doesn't support the delivery reports that are native to phone firmware.

You need to start all messages with *0# to get a proper delivery report.

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.

It will happen for any number.

You need to type *0# at the start of every message and then you will get a delivery report from O2.

The phones firmware will still report a message failure but the O2 delivery report will be accurate.

You can't unfortunately, unless you change networks.

Looks like something in either iOS15 or in the O2 carrier profile.

It may get fixed in an update of either I guess but I can imagine it's not high priority.
