My dad and brother are both on Verizon and my dad has a flip phone and has better signal up on the mountain than in the yard in ND. My brother has a smartphone and had terrible signal. They hunt around Steamboat.good morning folks. As the title cells i am from Texas and never hunted in CO before. I see the importance of an In Reach type device for the SOS features and tracking features. My question is an i know its not the same throughout the state but how bad is the cell reception really in the woods of Colorado? I have both AT&T and Verizon and am looking at Northern CO for chasing some elk for the first time this fall. Thanks in advance
