I have never had a landline....ever! (14 years on my own) Never saw the need to pay for 2 phones. We use cable internet...tried DSL for a year (hubby works from home via internet so it was important to compare the services between cable and phoneline) but we never plugged a phone in the wall (did not have one)
The only thing I would make sure before you go signing contracts is that your phone will work in your house!!! I have a couple of friends who just recently moved into a new house...both on the same provider...her phone works in certain sections of the house (eg: standing facing south in the east corner of the hallway)...meanwhile his phone does not work at all!!!! And supposedly this is the best provider in our town...haha...we have a different provider and seem to have great service everywhere...
I am a nobody; nobody is perfect, and therefore I am perfect.
