Coming from sky 40/10 package, all I did was sign up to plusnet. They did the rest didnt bother contacting sky. Was a bit confussing the information they gave though. Was told we couldn't keep the same number and an engineer needed to booked to come round. Gave them 3 available dates and got an email later in the week saying an engineer was coming round a few days earlier than planned (automated email).
Said engineer didn't show but last night our phoneline went dead around midnight the night before our booking and this morning the engineer was ment to turn up between 8am to 12. He never showed up. In the end I was at work so I got the gf to setup the box, all you do is plug it in, username password already on the box so she was up and running with 73/16 connection in a 2 min phone call. number is the same and no engineer came. I'm guessing they knew we had a mastersocket fitted when we got sky and already have the bt modem so was no need anyway.
