I live in a rural, mountainous area. Starting a year ago the signal strength where I live has gotten worse. The dead areas are larger. Signal strength used to be better. Perhaps they had tower sharing agreements that expired. My guess is they have gotten over-reliant on wi-fi calling to cut costs and reduce the number of towers. Sadly, I don't expect it to get better if and when 5G rolls out in the area. It's gotten to the point where I need to check out other providers. It's too bad. I've been with them more than 25 years. Service to rural areas is what used to distinguish them. No more.
