Hi Mo,
What speed does it say is available when you use the following link?
https://www.virginmedia.com/broadband/postcode-checker
It's possible that the Gig1 and M600 speeds aren't available in your area due to either the local network or capacity issues.
Info below from https://www.virginmedia.com/broadband/packages
The Legal Stuff > Offers section
Ultimate Volt: Maxit TV, Sky Cinema and Sky Sports (both in HD), Gig1 Fibre Broadband (average download speed 1136Mbps) (available with M350, M500 Fibre Broadband or M600 Fibre Broadband where Gig1 is not available, check availability here [Virgin Media Shop])
There have been a few posts saying that the sim card is only showing 250gb per month but it does get increased to unlimited once the volt benefits kick in.
The following staff <<< highlighted post >>> says
When taking out Ultimate Volt, you may be provided with a 250GB SIM Card, this should then be "supercharged" to Unlimited through the Volt Benefits that come as part of the package.
If your MyO2 app is showing the 250GB limit rather than "Unlimited", please call O2 Customer Services directly on 0344 809 0202 (or 202 from an O2 handset), so they can look into this further for you.
