Unknown caller and no 4G

[biggles911]

I've tried customer services umpteen times and they have been unable to solve 2 problems I have with O2 at the moment. I upgraded my contract and changed from a 4G sim to a 5G sim but in doing so my phone has been unable to keep 4G.. I'm not in a 5G area but my local shop informed me that the service would automatically default to the available 4G service. I reset the data settings and try selecting O2-UK manually and when I do this I get 4G service for perhaps 5 minutes or so then it disappears... I bought a brand new iPhone 14 Pro in the hope this would solve my problem that I had with my with my old iPhone but it hasn't. What am I supposed to do as customer services seem to be pretty ineffectual.... Also, all my calls come in as "unknown" even though they are in my contacts.... I have an e-Sim...

Please help me as I'm so hacked off with this......

I’ve had exactly the same issue.  Tried messaging multiple times, 202 several times, another forum and Twitter.  The data issue is fixed, but unknown caller persists.  Can anyone help?  Please 🙁

Unfortunately there are no longer any o2 community advisors @SairahHM

You will now have to either message o2 on social media, or try calling them.

Call them on 202 or 0344 809 0202 if you were pay monthly, or 4445 or 0344 809 222 if PAYG (or use 0800 032 1402 if you have no other line, and you can use Skype for free - Guide: A Guide to Skype ).

Alternatively you can message on social media: 

Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG)
