Bad cellular reception in Colorado (Boulder, Broomfield, Louisville)
August 27, 2017: My old cellphone (an iPhone) just died a tragic death, so I’ve been looking at cellphones, and also cellular carriers.

I can barely make a phone call with AT&T in my apartment in Broomfield, CO, and I also have problems when I travel around nearby Louisville and Boulder.
