Hi, I live in the 80602 Thornton area have had really poor service at home and out and about around I25 to federal blvd. The 4g barely has the smallest bar and it often goes 3g to nothing but the x. That happens a lot. I have a galaxy note 4, and the speed test came back at a dismal 135ms ping .4mb download and .01 upload. Is there anything I can do to get better service?
