SIM UNREGISTERED

Which phone model was it? And was it purchased from Koodo?
From your description, there is a chance that the phone was blacklisted. I would recommend you put the SIM into another phone to see if the SIM works normally. If the SIM works, the issue is from the device.

We have looked into it from our end and the services are active.
Have you tried re-inserting the sim card or trying it on a different device?

I've done this and tried everything
If you tried to put your sim in a confirmed working phone and it still doesn't work, then it sounds like the sim might have failed. In this case you will need a new sim and swap it over.
Did you also check your friend/family's sim in your phone to see if the issue followed the sim or your device?
