I tried to tell my dad that I should use GrapheneOS without a carrier and use Wi-Fi only. I’m trying to switch from iPhone. But then he gave me a counterargument and said, “Son, what if you’re stuck on the side of the highway with a broken down car or you need to call emergency services and you don’t have Wi-Fi?” What is the main counterargument to this?
You can carry a cheap second phone with battery removed (airplane mode is not sufficient) for this purpose specifically. In case you must call someone, you put in the battery and call.
