Hi there,
I rejoined O2 earlier this year and after a rather tedious process of having my number ported over (this failed several times and I was left without a working phone during a house move) I now have phone service. However, since the number port was fixed, all incoming calls show as either "Unknown" or "Private number" - Even calls from existing contacts.
I did contact O2 via Facebook chat several times and they suggested this was a known issue affecting multiple users, but they had no fix at that point in time and couldn't provide any kind of incident ID with it being a master incident.
I've thoroughly checked that my phone is configured how it should be, and research has lead me to believe that the caller ID info is something which passes through the carrier and has to be enabled at that end for me to see it, so I think some kind of a reset is needed in order to resolve the issue. I also can't access voice mail as it tells me it doesn't recognise the 901 number.
Please could I get some assistance with this? It has been having a huge impact as far as my safety on the phone and being exposed to spam callers, fraud attempts and other unwanted calls... My Pixel 7 Pro has features to combat these issues such as call screening and spam filtering, though this is rendered useless without caller ID info. The entire situation has left me feeling vulnerable throughout the process of moving house and up to now, any help would be hugely appreciated.

Unfortunately there are no longer any o2 community advisors @MMcK .

Did anyone get a solution to this? I am on a 3rd SIM trying to fix it. Nothing works and for some reason it takes half an hour to explain the problem to the (business) support centre....

o2 have developed this as a way to force the unknown caller issue to be fixed.
The alternative to this is to get your account completely rebuilt - so deleted and re-made...
