If nothing prevents this from happening, then when it does happen, I will make it a point to carry nothing but a laptop and a dumb phone, maybe a hotspot. If I need something from the internet, I will get it before the trip. If I can't get it on the trip, and forgot to beforehand, I will either find another way, or not do whatever it is.
I don't know why I don't do that now, honestly. Sounds pretty interesting.
