Every Incoming Call Shows No Caller ID or Unknown Caller

[ Edited ]

I received a new iPhone XR upgrade. Had to do a sim swap because the old sim didn’t work in the new phone. Now every call received shows Unknown Caller or No Caller ID, even from numbers in the contacts.
Tried resetting network settings but no luck.

O2 customer service thinks the phone is faulty but the O2 store thinks it’s a sim problem.

The same sim and another iPhone has the same problem. Another sim in the same iPhone does work.

I’m now in the second new sim after another sim swap today to try & resolve it. The O2 store have also sent out new carrier settings which they say can take up to 24 hours to activate.

The option in the settings for Show Caller ID is greyed out and can't be changed. 

Anyone else had the same problem and how was it fixed?

Thanks.

Sounds more like a setting on your account. 
You will have this problem if the plist option is not selected. 
Call customer service and ask them to check.

Thanks for your reply. I spoke with a few people in customer service this morning and got passed around a bit. No one seems to know what the plist option is but I was told the number is enabled for caller id. The issue has been escalated to tech support so I’ll post back when I know anything more.

So the Show Caller ID option can now be set but still all incoming calls are showing as No caller ID or Unknown. And no further response from O2. Not sure what the next move is. They keep trying to say I should do another sim swap or I should reset the phone again, all of which I’ve done multiple times.

If they can’t fix this would I have reasonable grounds to move the number to another network and terminate my contract early?

You would have to go through the official complaints process first to see if they could help before they may consider letting you out of contract,, however, I'll tag @EmilieT first to see if she can get any traction with O2 for you.

That’s really helpful. Thank you for your reply. I’m going to call them again tomorrow to ask if the tech support team has made any progress.
