In reply to PPP:
As previously said, yes it’s possible to have two broadband services if VM are using their own cable for everything. However, if you have a package and are transferring your actual landline number to your new provider (rather than getting a new number) there will be only a limited overlap period. As you can’t have the same number on more than one line, it will start the VM 30 day cancellation period. You should though have two broadband services for at least some overlap period depending on timings.
That said, a word of caution: in my case when I switched away from VM, instead of having the two broadband services overlap, as I planned, I ended up with no VM service (no phone, broadband, or tv) for a couple of weeks as VM switched me totally off within an hour of notifying them that I was transferring and to start the 30 day cancellation period. They were then a right pain to deal with. Long story short - They claimed human error, would reconnect broadband and tv, but they didn’t, then claimed it would take 72 hrs, but did nothing, further excuses/reasons, repeat until I gave up.
Edit: Oh be warned, if you have credit with VM, unless it’s changed since my switch, they take a minimum of 90 days to refund after the cancellation period has expired!1
