What's the question?

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.

@Kevin703 Are you being called by someone who is withholding their number? If so, there's nothing you can do. Don't answer the call and let it go to voicemail. If it's anything important, they'll leave a message. If it's becoming a nuisance you have the option of changing your number. Drastic and a pain in the rear to do, but an option nevertheless: How to change your mobile number - O2 Community

Thank you for your reply. The issue is that I'm getting it on all incoming calls. I haven't changed my phone or SIM card.

Sorry I'm new on here. I have recently had 'unknown' show on all incoming calls. Even those in my contact list.
