You can't transfer a landline number to another provider while keeping the existing line active.
So transferring your number wouldn't affect your broadband service directly as they're not dependent on one another on Virgin Media, but it would affect your monthly cost and be subject to any Early Disconnection Fees if you're still under a minimum term for your services.
I'd suggest speaking to Virgin to confirm any EDF cost for what you want to do as they can tell you exactly the costs for your bundle.
In regards to the transfer out itself, just wanted to make sure you were aware that your phone line would stop on your account once the number transfers out. There is no option to close it at a later date.

If you wish to port your number from Virgin Media to a different Operator, you will need to ask them to submit a port request to us. @BenMcr is correct in that if you currently have a bundle, your billing may change with the landline service removed.
To port, the line must also be active, so you cannot downgrade and then port. Instead, it will happen at the same time. The downgrade will not affect your broadband services as mentioned above.
I'd like to porting my landline number to a VPN, it's costing me a couple of hundred pounds a year and most calls are now on mobile so the only real benefit is making sure any contacts who only know the landline number can still find me.
Previous answers indicate it's possible, my question is whether it's the same for Fibre cable connections and conventional landline.
Also any feedback from anyone who's made the switch?
