landline phone
If you switch services, I presume you then would loose your landline/phone number unless it can be transferred/ported to a new provider via open reach cables if that is possible.
As the home phone number is widely used that could be an issue, or start to ditch using a landline number as most calls now go to mobile, I now get few calls on my landline but use it to ring out a lot.
The alternative is to just use mobile phones, but as service calls often last for long periods with music, a landline is more convenient and probably cheaper.
Can virgin provide the landline as a stand alone service or only with broadband, mine is not hub connected yet, but all landlines will eventually need a hub.
I am looking at options for the future which may involve a house move as well, so do not want to fix anything so will stay on monthly rolling providers to avoid exit costs.
The other option would be to install a BT landline phone with or without broadband, and use mobile broadband 4g or 5g via a router for home wi-fi, but not sure which provider to choose, I will look at costs.
