Hi @Jez2k,
Just to be clear it's not really the deals that you're confused about here, but moreso the specifics how the service would be installed/provided and keeping your landline number? Would that be a fair assessment? I will try and lay out some of that below.
Virgin Media use separate infrastructure to deliver your Broadband service and this should also be responsible for delivering your landline if they are both with the same provider. How is your current Virgin landline plugged in? Does it plug into your router or into a separate cable entirely at the wall?
With EE they operate on the Openreach network/infrastructure and as such if a customer is switching from an alternative network like Virgin, it requires their own separate cable (Copper or Fibre depending on the area) to be installed/present at the property to provide their services through.
With EE, the landline service is known as Digital Home Phone and it operates via plugging into a phone port on the back of the router and using the Internet connection for calls. This is how all landlines will be going forward.
When placing an order on EE you would be using the One Touch Switch service and before confirmation in the order process you should be told whether your landline number is able to kept successfully or not. There are a range of packages you can choose for your Digital Home Phone and it is on a 1-month rolling contract meaning you can switch packages or get rid of it entirely later to save a few quid (but you would then lose your number).
If you don't want your landline to affected in any way, your only option is to stay with Virgin. If your landline is still on the old analogue system, they will be moving it to their Digital landline system regardless within the next year or two I would imagine.
