Offline preparation is not just downloading a map. Before a remote leg, store the route, accommodation details, emergency contacts, official condition services and critical booking confirmations; then carry enough fuel, water and power margin that losing mobile data does not force an unsafe decision.

Carry independently of the phone
- Power bank and charging cable.
- Water, food and weather layer appropriate to the route.
- Written or screenshot copy of critical reservations and emergency contacts.
03
Remote-road rule
- Fill earlier than you think you need to.
- Do not follow an offline route through an official closure.
- Tell someone the expected corridor and arrival window when the route is genuinely remote.
04
Decision rule
Offline tools should preserve safe choices when signal disappears; they must never be used to override current authority instructions.
