Caller in my Contacts listed as Unknown Caller after phone switch

[Moggyman63]

I have a Virgin Media SIM that has been working happily on my Honor 9x Lite for the last 5 years.
I recently bought myself a Moto G85 and followed the procedure to copy all my apps & data from the old phone to the new one. Although it's a 5G phone, I only use 4G and all seems well apart from the default Google Phone app.

When a call comes in from a number that is already in my Contacts (synced to my Google account), it is listed as 'Unknown Caller'. This only happened on the old phone when it was actually true.

I thought it might be because this phone uses wi-fi calling - or it was until I just turned that off. I haven't had a call since so I don't know if this is the issue.

Has anyone else had a similar problem and managed to resolve it?

Thanks

@Dave-O2 Have you been able to discover anything?

For me, I have resolved this problem by getting a replacement SIM from O2.

There must be loads of people out there who were ported from Virgin Media to O2 and still use their VM SIMs. I really don't understand how O2's support people aren't aware of the issue and resolution. It was me who requested the new SIM (when I was with them for 2-3 hours earlier in the week) as I had an inkling that it might help - it wasn't offered by support as a potential fix.

Not exactly what I would call good service.

Glad to hear it's now OK.

There have been problems with some Virgin SIM cards but it is not common.

However, changing it for an up to date O2 one is always a good move. One of the reasons I made the suggestion early on
