Interesting in that they switched me to FIOS line a couple of years ago as copper was dying. I still have one phone but switched other to Comcast cable as cheaper package.
Verizon sends me the same bill as with copper and you get none of the extra services that come free with Comcast like caller id and long distance. Think phone company wants to keep old customers that don't have other services.
If dish is only way you can get internet and TV, maybe they have a package that include phone and you can eliminate the phone company.
