Quick answer: Choose a plan for the whole route, download outdoor maps, carry power and expect congestion at busy events. Keep tickets and accommodation details offline.

Avoid leaving it in direct sun or a parked vehicle. Heat can reduce performance and pause charging.
Prepare mountain days offline
Download routes and weather information; mobile coverage is not a safety system. See Slovakia hiking internet.
