Hi cciliber,
Thank you for reaching out to us in our community and welcome both here and to Virgin Media, sorry to hear you are unable to use Data even though calls and Text are fine, is it just 5G or are you unable to get any connection at all, are there any known issues showing on our Coverage Checker?
I was able to locate you on our system and it looks like you may have ported a number in to us, when this happens it can take up to 72 hours for things to settle.
Regards
Paul.
