What network are you on ? I take it it is a dual - sim device....
Are them e-SIMs or physical SIMs ?

OK.... how about if you get to Settings -> About phone ? The first line / lines should be your phone number/ numbers

They are both 'Unknown' in there as well, with no option to change.

Could this be anything to do with the SIMs being 3 or more years old?

My phone is the same, it doesn't show your number in the about phone settings, no option to add it either

Have you by any chance ported your number from another network to O2 ?

One of the numbers was ported in 2008 or 2009, I think, and the other was ported in 2018
