I was contacted a couple of hours ago by a SKY customer who wants to get rid of her eircom landline but is afraid that if she does she will lose her TV signal. I actually thought she might be right but Twitter tells me no. While you do need a phone line for Sky multi-room, you don’t if you just want a single box. Not having a landline means she won’t be able to access some of the interactive features on Sky but everything else should work as normal. Given that she is paying 40 quid a month for a telephone service she never uses and is in her mid-20s, by the time she hits 80, she will have saved herself more than €25,000 by simply cancelling the landline.
