Im truly struggling to understand what you mean. If your phone battery runs out, and you cant call anyone, do your legs and mouth suddenly stop working? Walk to a bus/train/transport station, use your words and pay for a trip home. obviously, if your money relies on the phone battery, yes you are truly stranded. But if you have a card or cash, you are not. It's quite simple. I guess you just have no imagination and can't fathom that people existed without phones or something? I'm asking in earnest, what do you mean?
