Hopefully the subject gives a clue.
I use facial recognition backed up by pin code on my phone. I've noticed that on this lockscreen, at the top right it say "O2 - No Sim Card", however when i unlock I do have mobile phone network with O2, and certainly not had any problems making or receiving calls.
not a major problem it seems, but I'm curious as to whether anyone else has noticed this?
Also hopefully also not a sign of impending problems.
