I think it is because AT&Ts service sucks so bad outside major metro areas (and in a lot of metro areas as well) that people want to be able to actually make a call. I have Verizon for both my personal and work lines and I can’t remember when I’ve ever dropped a call or had a hiccup in service while all my friends on Antique Telephone & Telegraph are cursing all the time about how bad their service is.
Well, they warned you about those cell phones destroying your brain. The memory is the first thing to go.
