The reply from goslow above is correct, however it does require VM to come out and some how run a cable between where the hub is and where the phone is. Now this can be quite intrusive (wires running along skirting boards, around door frames etc), or sometimes quite unobtrusive, especially if there is already a phone extension socket reasonably close to the hub or if the new cable can be run externally via the same hole in the wall that the coax cable comes from.
The other alternative, especially if you do never actually use the landline is to simply do nothing. The phone will stop working on switchover day, (maybe beforehand you set up a call divert on the line to send to a mobile number), just disconnect the handset and put it away in a cupboard and forget about it. Now probably, you still will need to carry on paying for a landline you aren't using (which it sounds like you have been doing anyway), as cancelling it, sometimes, seemingly perversely, increases the monthly cost, and doing so would start a new 18 month minimum term contract anyway.
Something to think about anyway.
Your point about not everyone having a phone next to the hub is valid, but really only for VM customers (well mostly). This initiative is being done by all telecom providers before 2025, but the majority of people will be on a BT/Openreach connection, where the internet connection is provided via the phone line and it's fairly normal to have the equivalent of the VM hub close to the 'master socket' where the phone is normally plugged in anyway. So for the majority of UK users, this really isn't an issue at all.
