I traveled from Pennsylvania to Florida by car and never got anything better than LTE service. I updated my phone and my carrier settings but I still only got LTE. With a new T-Mobile Magenta account, new iPhone 11, I thought I would get 3G in areas where available. I can’t imagine that not one state from Pennsylvania to Florida has 3G coverage in any area (hello, DC?) so what am I doing wrong? Thanks in advance!
