T-Mobile LTE Data Coverage (On the road - Detroit, MI)

First of all, I have to apologize if you didn't understand me clearly what I said. I edited the video when I was in Detroit, MI. It was too noisy and a mix of languages around me (English, Spanish, Arabic) that I decided to record my voice, but I was a little lost. I had to follow up what I sad according to the video. Thanks for your info, your advice that makes me to improve more about my video post!
