Fairphone have a partnership with Vodafone, who are the responsible carrier so you may like to contact support @f####.com to let them know of the current status and see what they have to say.
Yes the Virgin page in this instance (5G) refers to the FP3 https://devicesupport.virginmedia.com/customer/device/Fairphone/3Plus/scenario/enable-or-disable-5g-connection#l=vmcust&lHsim=tsvmcust&d=Fairphone/3%20Plus&hsimDevice=Google/Generic%20Android%20Device&s=LCX_Root&loc=virginmobile&isMarket=true&externalSessionId=befe232f729549088037c61d9a6d2161
I just don’t see why it’s a problem with the F4
So before you check out the page above what did you do?
I have contacted Virgin Media and it seems that it really is just an issue of them not having worked together on this yet…
The 5G band used in the UK seems to only be n78 so far, which the FP4 supports.
I’ll send in a fairphone support request now, I hope I get this done…
