For 20 years I kept a landline in my home primarily because of the alarm system. I finally called my alarm company with whom I’d been the same amount of time and said “cancel my subscription.” I said, “Because you guys cost too damn much a month and on top of that I have to pay $60 a month for a phone line I don’t need.”
Guy on the phone transfers me to the “Customer Loyalty Representative” and I explained my reasoning. Long story short? They dropped my monthly rate to comparable with cheaper ones near me AND they installed a cell-phone link system FOR FREE. Called the next day after installation and dropped the landline.
We kept the landline for two reasons. One for the security alarm system, and the other was that you could always use the landline when the power went out, which it did often where we lived.
Then one day the power went out and I tried to call the electric company on the landline which I had done probably 100 times over five years. No dial tone. Dead. When I called AT&T they asked if anyone had been in the area laying fiber optic cable. Yes; they had. They said landlines on fiber optic need electricity for some reason.
Cancelled the landline. Had the alarm company set us up for cellular connection.
I miss the landline.
