Yes, get rid of it.Use cellphones.
The only reason you might possibly need a landline is for Directivo, for just the initial setup.(I bought a 100ft phone extension and just updated it at my neighbors) and for DSL which is a non issue because now I have DSL without the active phone line.
DO IT! You will be FREE!
I don’t know about DirecTv, but you don’t have to have a phone line for Dish Network any longer.
I’ve been cell phone only for about 7 years and got Dish about six months ago. No phone line, no extra charge.
By the way, I’ve also never looked back. Ditching the landline is a no brainer.
