@BallyBee My Sky - EE switchover notification was at 2.23am e-mail ready to go, was a breeze no issues, kept the same sky ssid for the wireless, password etc, everything connected zero problems, went from the SR203 Sky router to the EE Smarthub+. Just take a note off the SKY details on the back off the SKY router, write them down and keep them safe, no doubt sky will request there router back when you have swapped over. Sky billing takes about 60 day's to complete so do expect to pay up to them, you will get it all back in time so keep an eye on it, i had to call them as they put it all towards future credit, had no items so called got the refund transferred back into the DD and that was it all over and done with.
There is no guarantee that it all goes smooth, if not get your needed up for work and sort the rest later.
Phone will be possibly out off commission for a couple off day's so you know, DV landline swap over is just not an instant, if it goes straight off then you are lucky.
