If your phone die, you replace it or do your operations at the ATM or at the counter during opening hours.
Replacing it is the problem. This can't be done at an ATM and if you're on a trip or you use an online bank, a counter may not be available.
Banks don't like you to go their office so in my own experience of replacing a smartphone I could activate the app on a new one rather easily.
