The answer should be no it shouldn’t eat up minutes but that’s not necessary the case.. I was on a European cruise and every time I just tried to use the App it started counting down minutes, if I disconnected, the App wouldn’t open, I went to the help desk, they claimed to fix it but nothing changed. I ended up just giving up on it and wasted all my allotted minutes. It wasn’t worth the hassle to stand in line longer than I already had to get it resolved…
