I don't know about the phone, I don't have one. But I think these habits are useful, even after spending years in and out of Oblivion.
When we row to shore and hike out in the woods all day, knowing that we can't call for help changed how we act in and out of the woods.
When we sailed across the pacific and accidentally sailed right into a cluster of chinese poachers, the way we acted was advised by us having been in Oblivion long enough where the social contracts are somewhat different.
