I have a Pixel 3 phone that is on the sprint network. My phone would receive cell service at 4G and no service at different spots in the park. I used the gotenna all across the park with success. The longest point was the middle of the parking lot to the very back of the park inside of a building. I am happy it worked and wished there were more users, But you will not have any problems while using the device at Six Flags Fiesta Texas in San Antonio Texas.
