Incoming calls - no caller ID

[Roman]

Since Thursday all of my incoming calls are coming through as ‘No Caller ID’. This includes all of my saved contacts. I’ve checked all of my phone settings, completed a network reset, installed the latest iOS,

called O2 twice (they just googled it and offered no solutions!), been to a store and done a SIM swap. When another SIM,

with another account and number, is placed into my phone it works fine! It seems to be baffling everyone. Anyone have any ideas??….

@Maggie81 

I'm afraid @O2nath_ci isn't on today. I'll tag @O2Georgina who should be able to help you. She's on from 8am.

[Maggie81]

Thank you I appreciate that.

@Maggie81 

Just a thought...Have you rebooted your phone? (Turned it on and off a few times?) If not, try that first.

[Maggie81]

Yeah I’ve done this about 20 times 

[Cleoriff]

OK, just wait for @O2Georgina then.

Best of luck.

[O2Georgina]

I’ve had this issue since Thurs 15 Sept. I’ve spoken to customer support who escalated it to tech, and tech have failed to respond, or provide a solution. Some good news - the customer support person I spoke to last week confirmed that if it hadn’t been sorted by yesterday, O2 would let me cancel my contract and issue a PAC code so that I can go elsewhere. 
I’ve added an O2 ESim for work, and that works fine (except for the rubbish 4G/5G because, you know, it’s O2).
