A powerline connection will not work for the phone, unfortunately.
Ask VM to modify your home phone wiring so you can use your existing landline extension sockets plugged into the phone connection from the VM hub.
VM should offer to do this free of charge for you as part of the switchover process.
Make sure they make modifications to your phone wiring so you can keep each piece of equipment in the same place (rather than the offer which sometimes crops up on here to move the hub to a different location)

Do I need to book a technician visit?
You’ll need to book a free technician visit if...
- You rely on your landline for accessibility needs or don’t have a mobile to make an emergency call – we’ll provide you with an Emergency Back Up Line so you’re always able to call emergency services.
- You’ve got connected devices such as a burglar alarm linked to a control centre, use a telecare device, or have other phones connected to extension sockets. You’ll need to contact your provider and let them know about the switch if you have any of these to make sure they’re compatible with a fibre service.
- The Hub and your home phone can’t be placed near each other.
