iPhone 11 A2111 compatibility with LTE bands in Europe (Portugal)

Maybe this is a stupid question, but I'm visiting the States in a few months and I was thinking of buying the iPhone 11 there. I'm aware that there are 3 models because of network compatibilities. In the States, they only sell the model A2111, and according to apple's website (iPhone LTE ), my country (Portugal) is not supported. After some research, I found from multiple sources(List of LTE networks in Europe , Frequency Check - Portugal ) that all the bands used in my Country are actually supported by this model. What I'm missing? Why would Apple remove the country from the list if it's actually supported?
