HD Video - Do I need to turn off when I go to Mexico or Canada?


    I just signed up for the ONE PLUS plan. So I'm paying the extra 5 bucks per month. I notice that there is a feature in my T-Mobile app where I need to turn ON HD Video. At which point it recommends I restart my iPhone in order to be able to stream HD video. My plan says HD Video is only free in the US.


    My question is, when I go to Canada or Mexico, will I be CHARGED on my bill if I forget to TURN OFF HD Video?
