Yup! that's why we use it as the primary other than it's installed "built-in" and is always on, and is 1/3 the price of starlink service. Our first year out, we only had TMHI and there were only a few spots in the Rockies that surrounding ranges blocked signal to nothing on phones and TMHI. This time, oddly enough a few locations in the Carolinas the congestion was too much and it showed full signal but would not connect to internet at all. Even took it to the T Mobile store where it worked fine on their store tower but down the road, nothing. I learned that when you use it mobile, the users in the area that have their address registered get preferred and anyone else gets deprioritized. This has only affected us in two locations in the past two years moving at least every two weeks most places between East Coast and CO
