Bad cellular reception in Colorado (Boulder, Broomfield, Louisville)

My old cellphone (an iPhone 5s) just died, so I’ve been looking at cellphones, and also cellular carriers. Skipping the cellphone part of the story, cellular reception in Colorado is notoriously bad. I can barely make a phone call with AT&T in my apartment in Broomfield, CO, and I also have problems when I travel in Louisville and Boulder.

Today I finally found a good map to show the problem at OpenSignal.com. This first image shows their cellular coverage map for AT&T in my area:

iPhone/iOS: How to quit using cellular data when using WiFi

I live in Colorado, where cellular reception can be very hit or miss. As just one example there are only two spots in my apartment where I can make a phone call. So when I’m at home trying to view a website using Safari on my iPhone and the page is loading really slow, I find it really annoying that my iPhone is trying to use my cellular data rather than my home wireless network (WiFi).

Note: Apple implies that the cellular data is “assisting” the WiFi, but with the poor cell reception here, I can confirm that this feature just slows down my iPhone internet speed.
